01F5 confirms exploitation of an unauthenticated RCE in BIG-IP's OAuth authentication gateway. An unauthenticated, network-only attacker can trigger a heap-based buffer overflow in F5 BIG-IP Access Policy Manager's OAuth-profile handling, reaching remote code execution on the TMM data plane. F5 confirms active exploitation; the exposure is limited to virtual servers configured with both an APM access policy and an OAuth profile. →
02Arista confirms exploitation of an SD-WAN orchestrator flaw that has no patch for two of its four release trains. Arista's on-premises VeloCloud Orchestrator (CVSS 10.0/9.5) is under active exploitation via a flaw reachable from the VCO web interface on deployments using certificate-based Edge authentication, requiring no VCO credentials. Fixes exist only for the 5.2 and 6.4 trains; 6.1.x and 7.0.x remain unpatched as of 2026-09-22, the same trains Arista already reported exploited via a separate flaw in July 2026. →
03Check Point patches a management-server zero-day it says has already been used in a handful of pinpointed attacks. An unauthenticated attacker can upload and execute an arbitrary script on Check Point Security Management Server, Multi-Domain Security Management Server, Log Server, Multi-Domain Log Server and SmartEvent via a directory-traversal and file-upload flaw. Check Point identified pinpointed exploitation on 2026-07-23, roughly two months before the 2026-09-22 fix; no LivePatch exists, only a hotfix or Jumbo Hotfix Accumulator. Bishop Fox published on 2026-10-01 an end-to-end root exploit method over the same port and a patch-state scanner, and says Check Point's second indicator does not fire on that route. →
NCSC Switzerland (BACS) reports a fraud chain that combines abuse of a legitimate Google account-security feature with vishing and app-password persistence (NCSC Switzerland, 2026-09-22). Attackers create their own Google account, register the victim's email address as its "recovery address," then generate an app password inside their own account and label it with social-engineering text impersonating a support case: "they then generated an app password in their own account and labelled it in the free-text field with: 'Kevin W. Case-ID: 834333 To view your case…'" (translated from German; NCSC Switzerland, 2026-09-22). "Google's automated system then sent an official, technically flawless security warning to the victim. Because the naming text was automatically carried into the email, it looked to the recipient as if Google were running an urgent support case with a case handler and case number" (translated from German; NCSC Switzerland, 2026-09-22). The victim therefore receives an authentic Google security alert whose attacker-chosen label makes it read like an active support ticket (NCSC Switzerland, 2026-09-22). A follow-up vishing call from a spoofed Swiss number posing as a Google landline, which got through despite Switzerland's mid-2026 rules against spoofed Swiss numbers from abroad, then pressures the victim to resolve the "compromise" via a phishing page hosted on the legitimate sites.google.com domain rather than accounts.google.com, whose embedded form sends entered credentials directly to the attackers (NCSC Switzerland, 2026-09-22). Once inside the real account, the attacker provisions their own app password within minutes, a special access code for older applications that works without two-factor confirmation, giving persistent access that survives a subsequent password change: "as a result, the perpetrators retained access to the account even after a password change. In the reported case, emails and contacts continued to sync unnoticed to a device abroad for an extended period after the attack" (translated from German; NCSC Switzerland, 2026-09-22).
Triage: legitimate Google administrators and helpdesks never call account holders unprompted about a security case; the tell is the free-text "case ID" riding inside an otherwise-genuine Google recovery-address notification, and any login page served from sites.google.com rather than accounts.google.com (NCSC Switzerland, 2026-09-22). Detection and hardening: an app password works without two-factor confirmation and kept the attackers in the account after a password change, so BACS advises deleting every app password and checking recovery addresses and automatic forwarding rules (NCSC Switzerland, 2026-09-22). A newly created app password on an account is therefore an incident-response signal in its own right.
They then generated an app password in their own account and labelled it in the free-text field with: "Kevin W. Case-ID: 834333 To view your case…".
Google's automated system then sent an official, technically flawless security warning to the victim. Because the naming text was automatically carried into the email, it looked to the recipient as if Google were running an urgent support case with a case handler and case number.
As a result, the perpetrators retained access to the account even after a password change. In the reported case, emails and contacts continued to sync unnoticed to a device abroad for an extended period after the attack.
BACS describes the Google alert as official and technically flawless, with the attacker's app-password label carried into it automatically (NCSC Switzerland, 2026-09-22). It does not say the rest of the email cannot be altered, a claim the entry previously made. BACS also describes an app password as a special access code for older applications that works without two-factor confirmation, and says the phishing page's form sent entered credentials directly to the attackers (NCSC Switzerland, 2026-09-22).

CVE-2026-94127 (CVSS 3.1: 9.8, CVSS 4.0: 9.3, CWE-122 heap-based buffer overflow) is a vulnerability in F5 BIG-IP Access Policy Manager (APM) reachable on the Traffic Management Microkernel (TMM) data plane; F5 states "this is a data plane issue; there is no control plane exposure" (F5, via SecurityOnline, 2026-09-22). It triggers only on a virtual server configured with both an APM access policy and an OAuth profile. "When a BIG-IP APM access policy and an OAuth profile are configured on a virtual server, specific malicious traffic can lead to remote code execution (RCE)" (F5, via SecurityOnline / Daily CyberSecurity, 2026-09-22): the OAuth-profile request-handling logic writes attacker-influenced data into a heap allocation without validating its size, corrupting adjacent heap memory and ultimately hijacking control flow inside TMM, exploitable by an unauthenticated, network-only attacker with no user interaction. Affected: BIG-IP APM 21.1.0, 17.5.0–17.5.1, and 17.1.0–17.1.3. Fixed via engineering hotfixes (Hotfix-BIGIP-21.1.0.2.0.30.22, Hotfix-BIGIP-17.5.1.9.0.160.12, Hotfix-BIGIP-17.1.3.5.0.41.14); F5 also offers an emergency iRule mitigation through F5 Support for organizations that cannot immediately apply the hotfix. "The vendor confirmed active exploitation in the wild" (CERT-EU, Security Advisory 2026-013, 2026-09-22); CISA added it to KEV the same day (CISA KEV, catalogue version 2026.09.22) with a 2026-09-25 remediation deadline.
Detection concept, directly from the vendor's own compromise-assessment guidance (vendor-neutral telemetry classes): repeated OAuth "UserInfo" request failures with an "invalid_token" error code from a single source in a short window (F5's own threshold is 10 or more occurrences) in the APM authentication log; an unexplained rise in the failed-OAuth-request counter relative to total OAuth requests, queryable via the platform's internal OAuth statistics; administrative-audit-log review around the same timestamps as any OAuth failure spike, correlated with a TMM process crash or core file caused by the microkernel entering an abort loop. F5's own framing: "at a high level, multiple OAuth authentication failures, followed by suspicious commands, shortly followed by a TMM SIGABRT is the combination that should lead to human review of the system" (CERT-EU, Security Advisory 2026-013, 2026-09-22); no single signal is by itself an indicator of compromise. Triage: an isolated OAuth authentication failure or an occasional TMM restart happens in normal operation; the correlated sequence (failure spike, then suspicious commands, then a TMM crash) is the discriminator. Hardening: inventory every virtual server pairing an APM access policy with an OAuth profile, since the exposure is entirely configuration-gated; apply the engineering hotfix or the emergency iRule; internet-facing instances of this authentication-gateway component are the highest remediation priority.
When a BIG-IP APM access policy and an OAuth profile are configured on a virtual server, specific malicious traffic can lead to remote code execution (RCE).
This is a data plane issue; there is no control plane exposure.
The vendor confirmed active exploitation in the wild
At a high level, multiple OAuth authentication failures, followed by suspicious commands, shortly followed by a TMM SIGABRT is the combination that should lead to human review of the system.
watchTowr Labs published a patch-diff analysis of CVE-2026-94127 on 2026-09-23 that makes the trigger public. The fix adds a size check before an Authorization header is copied into a heap buffer allocated at 0x4100 bytes on the OAuth UserInfo path; before the patch there was no check, so a longer header overflows the buffer (watchTowr Labs, 2026-09-23). In watchTowr's lab a single GET request to the OAuth userinfo endpoint, carrying a Bearer Authorization header larger than 0x4100 bytes, crashed the traffic-management process (watchTowr Labs, 2026-09-23). watchTowr found that the process binary is not position-independent and that an object holding a function pointer usually landed just past the overflowed buffer in its runs, which lets the overflow redirect execution; SELinux blocked direct process execution, so it turned to the hook script the appliance runs each time the traffic-management process crashes and appended a command to it (watchTowr Labs, 2026-09-23). The request-side signal to add to the authentication-log signals above is therefore an Authorization header far larger than a normal Bearer token sent to the OAuth UserInfo path, followed by a crash and restart of the traffic-management process.
CVE-2026-93952 (CVSS 3.1: 10.0, CVSS 4.0: 9.5, CWE-20 improper input validation) affects on-premises VeloCloud Orchestrator (VCO), the SD-WAN control-plane server that provisions and manages VeloCloud Edge devices. NCSC-NL classes the weakness as path traversal (NCSC-NL, 2026-09-22). Arista states the flaw "may allow a remote attacker to access privileged internal functionality and impact the VCO host," compromising confidentiality, integrity and availability of the orchestrator and the data it manages, and that a compromised VCO may in turn give an attacker access to the Edge devices it manages. Exposure is configuration-dependent: only VCOs with certificate-based Edge-to-VCO authentication configured are affected. "VCO is exposed if certificate based authentication from the VeloCloud Edge to VeloCloud Orchestrator (VCO) is configured. Access to the public portion of the VeloCloud Edge authentication certificate is required. A successful attack requires network access to the VCO web interface. VCO tenant or operator credentials are not required for this exposure" (Arista Networks, Security Advisory 0183, 2026-09-22). Affected release trains: 5.2 (5.2.3.15 and below), 6.1 (6.1.3.7 and below), 6.4 (6.4.2.7 and below), and 7.0 (7.0.0.2 and below). As of 2026-09-22, fixes exist only for the 5.2 release train (5.2.3.16+) and the 6.4 release train (6.4.2.8+); Arista states "releases in other release trains that fix this will be added over time" (Arista Networks, Security Advisory 0183, 2026-09-22), the 6.1.x and 7.0.x trains have no fix yet, with no committed date. Arista's Hosted and Dedicated VCO offerings were already patched. "This issue was discovered externally and is known to be actively exploited" (Arista Networks, Security Advisory 0183, 2026-09-22); Arista does not disclose when exploitation began or its scale. The affected release trains are the same ones Arista reported exploited via a separate, unrelated VCO command-injection flaw disclosed two months earlier: "the vulnerability, tracked as CVE-2026-16812 (CVSS score: 10.0), is a case of operating system command injection that could pave the way for arbitrary code execution" (The Hacker News, 2026-07-28, reporting on Arista Security Advisory 0144), that flaw was fixed across all four trains at the time (5.2.3.14+, 6.1.3.4+, 6.4.2.4+, 7.0.0.1+); this one leaves two open. VCO has now been targeted twice within roughly two months. CISA added CVE-2026-93952 to KEV the same day (CISA KEV, catalogue version 2026.09.22).
Triage: Arista flags outbound HTTP or HTTPS activity from the VCO host only when it is unexpected, and advises blocking outbound ports not needed for normal activity, so compare outbound connections with the orchestrator's known update and integration destinations rather than treating all outbound traffic as hostile (Arista Networks, Security Advisory 0183, 2026-09-22). A configuration or maintenance change with no matching administrator action is the other discriminator Arista names (Arista Networks, Security Advisory 0183, 2026-09-22).
This issue was discovered externally and is known to be actively exploited.
VCO is exposed if certificate based authentication from the VeloCloud Edge to VeloCloud Orchestrator (VCO) is configured. Access to the public portion of the VeloCloud Edge authentication certificate is required. A successful attack requires network access to the VCO web interface. VCO tenant or operator credentials are not required for this exposure.
Releases in other release trains that fix this will be added over time.
Arista's advisory does not name an authentication-mode change as a mitigation. Its interim controls are restricting web-interface access to trusted administrative networks, monitoring for unexpected outbound traffic, backdoor daemons and webshells, blocking outbound ports not needed for normal activity, and reviewing administrator activity (Arista Networks, Security Advisory 0183, 2026-09-22). Arista also does not say which certificate modes meet its exposure condition (The Hacker News, 2026-09-22), so switching Edge authentication to PSK mode is an untested option rather than a vendor control. Some outbound traffic from the orchestrator is normal, and Arista flags only unexpected outbound activity (Arista Networks, Security Advisory 0183, 2026-09-22). As of 2026-09-30 the advisory still lists no fix for the 6.1 and 7.0 trains (Arista Networks, Security Advisory 0183, 2026-09-22).
Check Point discloses a pre-authentication directory-traversal and file-upload vulnerability that lets an unauthenticated attacker upload and execute arbitrary scripts on the Check Point Management Server (Check Point Support, sk1000171, 2026-09-22), which in Check Point Research's words "allows an attacker to execute a script from an arbitrary path and load an arbitrary Java class" (Check Point Research, 2026-09-22). It affects Security Management Server, Multi-Domain Security Management Server, Log Server, Multi-Domain Log Server and SmartEvent; Smart-1 Cloud already carries the fix, and Security Gateway appliances and Spark Firewall are not affected. Check Point states it identified "a handful of pinpointed attacks" exploiting this as a zero-day on 2026-07-23 (Check Point Research, 2026-09-22), roughly two months before the 2026-09-22 disclosure and fix. Affected versions: R82.20 (all takes), R82.10 Jumbo Hotfix Take 44 or lower, R82 Take 126 or lower, R81.20 Take 166 or lower, R81.10 Take 190 or lower (end-of-support), and the end-of-support R80/R80.10–R80.40/R81 lines. Fixed in the R82.20 Security Hotfix, or Jumbo Hotfix Accumulator R82.10 Take 45+ / R82 Take 127+ / R81.20 Take 170+ / R81.10 Take 192+; Check Point published no fix for the end-of-support trains older than R81.10, and upgrading is the only remediation for them (Bishop Fox, 2026-10-01). Check Point states plainly "because of the nature of the fix, a LivePatch is not be available for this issue" (Check Point Support, sk1000171, 2026-09-22); the September LivePatch (Take 28/29) that addressed the unrelated CVE-2026-91843 flaw does not cover this vulnerability (The Hacker News, 2026-09-22). CISA added it to KEV the same day (CISA KEV, catalogue version 2026.09.22). This is a distinct, unrelated flaw from CVE-2026-85102 (a separate Check Point Security Gateway/Spark VPN certificate-validation RCE, disclosed 2026-09-09, with exploitation attempts reported from 2026-09-12 (Check Point Research, 2026-09-22)), with different components and no CVE overlap.
Detection concept, per Check Point's own two independent indicators of compromise (Check Point Support, sk1000171, 2026-09-22): first, a pre-authentication login attempt whose username field is anomalously long (over 1,000 characters) in the management-process log, occurring at the same timestamp as a management-process core dump, indicates a crash consistent with exploitation attempt; second, a resource-loading error referencing a file path containing parent-directory-reference sequences in the same log, which Bishop Fox says fires only when an upgrade-tools load fails and not on the route it published (see the 2026-10-04 update below). Triage: the first indicator is diagnostic only as its own correlated pair: an anomalously long username alone is not, and Bishop Fox attributes that crash signature to the separate CVE-2026-91843, not to this traversal (Bishop Fox, 2026-10-01). The second indicator, a traversal-pattern sequence inside the resource-loading error path, signals an attempt on the upgrade-service route when it appears, but its absence says little (Bishop Fox, 2026-10-01). Hardening: because no LivePatch exists, restrict network reachability to the management web service (Check Point names TCP/19009 specifically) to trusted administrative IP ranges via the platform's Trusted Clients or implied-rule mechanism, which Bishop Fox calls Check Point's primary mitigation (Bishop Fox, 2026-10-01).
A directory traversal and file upload vulnerability allows an unauthenticated attacker to upload and execute arbitrary scripts on the Check Point Management Server. This vulnerability is exploited in the Wild. Check Point is aware of a handful of customers who have been attacked.
Bishop Fox published on 2026-10-01 a lab reproduction of an unauthenticated root code-execution chain on unpatched R81.10 and R82.10 management servers, run end to end over TCP 19009 (Bishop Fox, 2026-10-01). The chain mints a session by presenting the server's own internal certificate name, which the server accepts from a caller-supplied string without checking that a certificate was presented, then uses the file service to write a file anywhere as root; overwriting a stock scheduled-task file makes the system's cron daemon run the attacker's command as root with no further request, and the output is read back over the same session (Bishop Fox, 2026-10-01). Bishop Fox confirmed two further routes from the same write to code execution and says closing any one leaves the others standing (Bishop Fox, 2026-10-01). The post describes the chain but links only a patch-state scanner, not the exploit script.
Bishop Fox reads the hotfix as closing three defects while the advisory names two: the forged login, the unbounded file write and the upgrade-service parameter validation, with either of the first two alone breaking the chain; this is its comparison of the shipped code, not a Check Point statement (Bishop Fox, 2026-10-01). Its scanner reads patch state from outside with one benign request to the management port and, per its README, does not detect prior compromise (Bishop Fox, 2026-10-01).
Bishop Fox says Check Point's second indicator fires only when an upgrade-tools load fails and is never reached by this route, so it leaves neither the error line nor the parent-directory sequence, and that a genuine upgrade can trip it; it calls the first indicator, an over-long username next to a core dump, the crash signature of the separate CVE-2026-91843 and not evidence of this traversal (Bishop Fox, 2026-10-01). An exposed, unpatched server with neither log sign is therefore not shown to be clean. Its hunting advice is file-integrity monitoring of scheduled-task directories, startup and SSH key paths, the normally empty upgrade-tools directory, the CPM configuration files and anything new in the output-staging directory, paired with execution telemetry, cron reload events and an alert on the management Java process spawning a shell, because a scheduled hash check can miss stock files restored byte for byte (Bishop Fox, 2026-10-01). It also notes that the Trusted Clients restriction is a permissions setting that emits an implied rule, so a rule-base audit alone can miss it (Bishop Fox, 2026-10-01).
VulnCheck's Initial Access Intelligence team discloses three unauthenticated vulnerabilities in Virtualizor, Softaculous' commercial VPS/hypervisor control panel (KVM/OpenVZ/LXC), all reached through a single mis-scoped pre-authentication guard. In enduser/admin.php, the admin panel (ports 4084/4085) redirects every request to the login page except one: "the redirect that guards the admin panel fires for every action except one. That one is login" (VulnCheck, 2026-09-22). The act=login request that should only reach the login page instead falls through the guard and reaches an unauthenticated from_billing_module handler with no session, API key or slave credentials. CVE-2026-43641 (CWE-78 OS command injection) is the flagship: the handler's uid field, taken unvalidated from an unserialized attacker POST body, is concatenated into a shell command inside billing_unsuspend() → vexec() → proc_open(), giving remote root command execution. VulnCheck states "verified on the lab: /tmp/x reads uid=0(root) gid=0(root) groups=0(root)" (VulnCheck, 2026-09-22). Exploitation requires an existing in-house-billing account on the target that is currently suspended and paid up, server state that exists on any install using that billing mode by design, and no separate enumeration step is needed because the same request path is a non-destructive timing oracle: injecting a sleep payload via the uid field hangs the response only for a valid, eligible uid. The bug additionally needs MySQL's default non-strict sql_mode, which VulnCheck confirmed is what Virtualizor's own bundled MySQL 5.5.62 stack ships uncorrected, so this is a default-production condition, not a lab artifact. The root-level impact is possible because Virtualizor's EMPS stack splits PHP execution across separate php-fpm pools by port: the admin-panel index.php on ports 4084/4085 runs in a pool that executes as root, while the client panel and every other .php file run in an unprivileged pool. The exploit therefore never drops a PHP web shell (which would run unprivileged) and instead relays each command's output to a randomly named static file written into the webroot and served directly by nginx.
CVE-2026-43642 (CWE-502 PHP object injection) reaches the same unauthenticated handler's native unserialize() call on attacker-controlled POST data with no allowed_classes restriction; no working exploitation gadget chain exists in the stock code today, but the primitive is live for any add-on or plugin that introduces a class with a __wakeup or __destruct method. CVE-2026-43643 (CWE-639 authorization bypass through a user-controlled key) lets an unauthenticated caller zero out or inflate any tenant's account balance through the same handler's whmcs branch, via a parameterized but unauthenticated balance UPDATE with no ownership check. VulnCheck audited 3.2.9 patch 7 and, in a 2026-09-20 re-test from decoded source, found patch 8 vulnerable as well (VulnCheck, 2026-09-22). "Softaculous patched all three in 3.2.9 patch 9 (2026-09-01), and the fix carries into 3.3.0 (2026-09-09), the current build. Patch 7, the build audited above, and patch 8 are both still vulnerable" (VulnCheck, 2026-09-22). The fix requires a validated API call (HMAC API key or admin credentials) before the billing hook is reachable at all, casts the uid value to an integer before it reaches the shell, restricts the deserialization call with allowed_classes => false, and adds an ownership check to the balance-write branch. VulnCheck's post does not state whether it has observed in-the-wild exploitation; it also turned the command-injection flaw into a self-contained exploit module, built on VulnCheck's own open-source "go-exploit" framework, that fingerprints the Virtualizor admin panel, finds an eligible suspended account on its own via the timing oracle, and returns a root shell with no credentials and no account information supplied by the operator. VulnCheck's post demonstrates this module against its own lab instance and does not state that the CVE-specific module itself was released publicly, only that it is built on the publicly available go-exploit framework.
Detection concept: VulnCheck's exploit reaches the admin panel on ports 4084/4085 with act=login and from_billing_module set and a serialized billing_data field in the POST body (VulnCheck, 2026-09-22). On any self-managed Virtualizor installation, look in admin-panel access logs for unauthenticated requests carrying that combination, since a login request has no use for billing-module parameters. The injected commands run in the admin panel's root php-fpm pool and relay their output through randomly named static files written into the webroot and then removed (VulnCheck, 2026-09-22), so in host telemetry alert on processes spawned by that pool outside Virtualizor's own process tree and on short-lived static files created in the webroot outside a deployment. Triage: in the fixed build the billing hook runs only after a validated API call, a valid API key or admin API credentials (VulnCheck, 2026-09-22), so a request reaching the billing handler with no session or API-key context is the discriminator, whatever its act parameter claims.
The redirect that guards the admin panel fires for every action except one. That one is login.
Verified on the lab: /tmp/x reads uid=0(root) gid=0(root) groups=0(root).
Softaculous patched all three in 3.2.9 patch 9 (2026-09-01), and the fix carries into 3.3.0 (2026-09-09), the current build. Patch 7, the build audited above, and patch 8 are both still vulnerable
VulnCheck's disclosure gives no CVSS scores for the three flaws (VulnCheck, 2026-09-22). The scores shown earlier are not on that page and are no longer shown. The weakness classes, CWE-78, CWE-502 and CWE-639, come from VulnCheck's own table (VulnCheck, 2026-09-22).
The European Court of Auditors published Special Report 19/2026 on 2026-09-22, concluding that the EU's cooperation framework for detecting and responding to cybersecurity incidents (the CSIRTs network, EU-CyCLONe, the European Cybersecurity Alert System, the Commission's cyber situation centre and the EU Cybersecurity Reserve) is only partially effective (European Court of Auditors, Special Report 19/2026, 2026-09-22). Three structural gaps drive the finding: NIS2 transposition delays ("member states had until October 2024 to transpose the NIS 2 Directive into national law, but only two met the deadline" (European Court of Auditors, Special Report 19/2026, 2026-09-22)); national-security legislation that lets member states withhold incident information with no obligation to share it; and no EU-wide platform to correlate cross-border incidents in real time. As its case study, the report documents that the September 2025 Collins Aerospace ransomware attack on airport passenger-processing systems; "the disruption was most severe at London Heathrow Airport, Brussels Airport, Berlin Brandenburg Airport, and Dublin Airport" (European Court of Auditors, Special Report 19/2026, 2026-09-22), was never classified as "significant" or "large-scale cross-border" under NIS2 by the affected member states, named by heise as Germany, Belgium and Ireland (heise online, 2026-09-22): "no member state treated this incident as being either significant or large-scale cross-border. Therefore, none of the affected member states formally notified ENISA or other member states of the incident. The CSIRTs network did not advise EU-CyCLONe, which therefore did not support the coordinated management of the incident" (European Court of Auditors, Special Report 19/2026, 2026-09-22). EU-wide, "in 2025, only 14 significant cross-border incidents were reported, by seven member states" (European Court of Auditors, Special Report 19/2026, 2026-09-22), and "no cybersecurity incident has been considered 'large-scale' by any member state since 2016", despite events the report itself cites as comparably severe, including WannaCry and NotPetya (European Court of Auditors, Special Report 19/2026, 2026-09-22). The Court's Recommendation 1, targeted for 2027 (information-sharing analysis and cross-border-incident detection) and 2028 (real-time incident reporting), calls for a Commission/ENISA-led review of national-security restrictions on information sharing and progress toward real-time incident reporting to ENISA (European Court of Auditors, Special Report 19/2026, 2026-09-22).
Switzerland sits outside NIS2's scope but is embedded in the same cross-border supply chains (aviation, finance, cloud) the report's case study concerns. The finding that formal EU cross-notification cannot be relied on for early warning is a direct input to how Swiss public-sector CERTs and GovCERT.ch should weight direct primary-source monitoring of national CERTs and vendor advisories against EU cross-notification channels, since a serious incident affecting an EU supply-chain partner may never surface through the formal EU mechanism at all.
Yet, no member state treated this incident as being either significant or large-scale cross-border. Therefore, none of the affected member states formally notified ENISA or other member states of the incident. The CSIRTs network did not advise EU-CyCLONe, which therefore did not support the coordinated management of the incident.
Member states had until October 2024 to transpose the NIS 2 Directive into national law, but only two met the deadline.
In 2025, only 14 significant cross-border incidents were reported, by seven member states.
European Court of Auditors, Special Report 19/2026
Despite the significant impact of the incident, the affected member states (Germany, Belgium and Ireland) reportedly did not notify the EU cybersecurity agency ENISA or the other member states accordingly, the report criticizes. (translated from German)
The five EU-level networks and mechanisms the Court assessed are the CSIRTs network, EU-CyCLONe, the European Cybersecurity Alert System, the Commission's cyber situation centre and the EU Cybersecurity Reserve (European Court of Auditors, Special Report 19/2026, 2026-09-22). This entry previously listed the Cyber Blueprint in place of the cyber situation centre. The Blueprint is one of the policy instruments the report describes, not an assessed mechanism.
Austria's Netz- und Informationssystemsicherheitsgesetz 2026 (NISG 2026), its NIS2 transposition, enters into force on 1 October 2026, two years late (heise online, 2026-09-22). It creates the Bundesamt für Cybersicherheit (BCS) under the Interior Ministry as the central authority and supervisor for "essential" and "important" entities in sectors including energy, transport, health, drinking and waste water, digital infrastructure, industry and food supply (Austrian BMI, via OTS, 2026-09-22). Municipalities are excluded, and the BCS takes over the civilian-administration GovCERT and oversight of the sectoral CERTs and CERT.at (heise online, 2026-09-22). Covered entities must send an early warning without delay and in any case within 24 hours of becoming aware of a significant incident, and a fuller notification within 72 hours (Austrian BMI, via OTS, 2026-09-22). Managers must attend security training, and the BCS will run active vulnerability scans of essential entities' internet-facing systems (heise online, 2026-09-22). Blocking or defending against those scans is punishable from 1 October (heise online, 2026-09-22). Penalties under the law are imposed not by the BCS itself but by the competent district administrative authority at the BCS's suggestion (heise online, 2026-09-22).
For Swiss cantonal authorities, a nearer reference point is Canton Bern: its information- and cybersecurity law (ICSG) and implementing ordinance (IDSV) enter into force on 1 November 2026, and with the IDSV the canton is introducing its own platform for reporting security incidents, vulnerabilities and cyberattacks (Kanton Bern KAIO).
With the entry into force of the Network and Information System Security Act 2026 (NISG 2026), the new Federal Office for Cybersecurity (BCS) officially begins its work on 1 October 2026.
An initial early warning is required without delay, in any case within 24 hours of becoming aware of the incident. A more detailed notification must be made without delay, at the latest within 72 hours.
Austrian Federal Ministry of the Interior (BMI), via OTS press release
Blocking or defending against such state scans is punishable from 1 October, and affected essential entities must also actively cooperate on request.
Canton Bern's information- and cybersecurity law (ICSG) and its implementing ordinance (IDSV) enter into force on 1 November 2026, and the canton's incident-reporting platform comes with the IDSV (Kanton Bern KAIO). An earlier closing sentence credited the ICSG with a 24h/72h reporting clock and compared the Austrian law with a Finnish reporting checklist without sources, and both claims are removed.
heise's word for obstructing the BCS scans is "strafbar" (punishable), and it does not say whether that makes obstruction a criminal offence. It adds that penalties are imposed not by the BCS itself but by the competent district administrative authority at the BCS's suggestion (heise online, 2026-09-22).
CISA added CVE-2026-85102 to its Known Exploited Vulnerabilities catalog on 2026-09-22, and Check Point's own advisory confirms a wave of exploitation attempts against Spark Firewall customers globally beginning 2026-09-12, three days after the fix shipped, using certificate-based Mobile Access logins from anonymization infrastructure. A September 14 advisory update also reveals a coverage gap in the original fix affecting offline LivePatch installs on specific older hotfix baselines, closed by a second, hardened LivePatch (Take 26) issued two days after exploitation began. Exploitation status moves from unexploited to confirmed exploited; priority moves from high to critical. CVE-2026-85103 is unaffected and remains not confirmed exploited.
CISA added CVE-2026-85102 to its Known Exploited Vulnerabilities catalog on 2026-09-22 (CISA KEV, catalogue version 2026.09.22), and Check Point's own advisory confirms the reason: "Check Point disclosed the vulnerability and released fixes on September 9, 2026. At the time, we had no evidence of exploitation. We are now observing exploitation attempts against Check Point Spark customers globally" (Check Point Research, 2026-09-22). "Starting September 12, 2026, we observed a wave of exploitation attempts against Spark customers. The attempts originated from anonymization infrastructure, including VPN services and proxies" (Check Point Research, 2026-09-22), three days after the 2026-09-09 fix shipped. Check Point's own advisory sk1000117 carries a September 14 update explaining why some already-patched customers remained exposed during that wave: for customers who installed the Offline LivePatch Package while running R82.10 Jumbo Hotfix Take 24 or lower, R82 Jumbo Hotfix Take 107 or lower, or R81.20 Jumbo Hotfix Take 146 or lower, "following additional research, we identified a rare scenario in which customers must install Check Point Live Patch Take 26, which provides enhanced coverage for this CVE" (Check Point Support, sk1000117, updated 2026-09-14), a coverage gap in the original fix, closed by a second, hardened LivePatch issued five days after the initial patch and two days after exploitation attempts began. CVE-2026-85103, the companion heap-overflow certificate-decoding flaw, is unaffected by this gap and remains not confirmed exploited. Check Point's own hunting guidance: review logs for anomalous certificate-based Mobile Access logins without limiting the search to the observed certificate subjects, and treat follow-on internal port or service scanning from a logged-in Mobile Access session as second-stage activity warranting investigation.
CERT Polska's own technical write-up (2026-09-22) corrects this entry's account of the exploited chain: CVE-2026-67276 is not the chain's entry point and is not confirmed exploited as part of MikroTrick; it is a separate, narrower RSA-key-impersonation flaw needing a known account and modulus in advance, limited to that one account. The actual, configuration-independent entry point is CVE-2026-67279, an SSH rekey-during-authentication state-confusion bug that lets an unauthenticated client reach channel handling without ever completing authentication. Corrected the title, summary, the two CVE records' exploitation status and the body's mechanism description accordingly, and added the RouterOS Flagged mechanism's exact trigger condition.
CERT Polska's own technical analysis of MikroTrick (CERT Polska, 2026-09-22) states plainly that "some publications incorrectly associated CVE-2026-67276 with the MikroTrick chain"; it "is a separate vulnerability that allows an attacker to impersonate a user authenticated with an RSA key," requiring the target account name and RSA modulus in advance and granting access only to that one account, "significantly less suitable for a mass attack that works regardless of device configuration." This entry previously named CVE-2026-67276 as the chain's forged-signature entry point; that attribution is wrong, and CERT Polska does not confirm CVE-2026-67276 as separately exploited in the wild. The actual, configuration-independent entry point is CVE-2026-67279: "vulnerable versions of the RouterOS SSH server handled a rekey initiated during user authentication incorrectly. When the rekey finished, the server unconditionally moved from the temporary rekey state to channel handling instead of resuming the interrupted authentication" (CERT Polska, technical analysis, 2026-09-22), reaching a session channel despite never completing authentication, the precondition CVE-2026-86060's crafted "-2" username then abuses to set an attacker-controlled policy mask. The exploitation status is corrected accordingly: CVE-2026-67276 moves from exploited to patch-available and CVE-2026-67279 moves from patch-available to exploited, both now classed as auth-bypass. Separately, the fixed releases' Flagged self-check specifically watches at startup for an "ops" account newly created in the privileged "full" group, disabling it and logging a warning when found, a more precise trigger than this entry previously stated.
Gambit Security's Threat Intelligence team recovered a financially motivated operator's exposed staging server and reconstructed a campaign, running since July 2026, in which three off-the-shelf open-source AI agent harnesses conduct nearly the entire intrusion lifecycle unattended against online retailers. Strix, an open-source AI pentesting tool run via OpenRouter (GLM 5.2, later switched to DeepSeek v4 Pro), performs autonomous vulnerability discovery: 146 deep-mode scans against 138 hosts between 23–31 August 2026, burning 633 hours of scanner time within 195 hours of wall-clock time. Cairn, an autonomous exploitation engine on DeepSeek v4.1 Flash, receives a target domain and an objective and runs unattended for hours until it gets a shell or admin access: "between 10 and 15 September alone, 105 attack projects were launched and at least 27 companies were compromised to varying degrees" (Gambit Security, 2026-09-22). Hermes, an open-source autonomous agent with persistent memory and skills the agent writes and edits itself, orchestrated the campaign end to end, running on Anthropic Opus 4.6 ("after newer models refused its requests") under a Chinese system persona the operator loaded, titled "SOUL - Red Team Operator". The operator had added a custom skill that strips Hermes's own content-safety filters, and drove the campaign through only 1,951 short, largely Chinese-language operator prompts across 260 sessions, with most of the actual attack work running autonomously between those prompts (Gambit Security, 2026-09-22).
One fully documented Cairn project illustrates the chain, though Gambit is explicit that each victim's actual path was chosen dynamically through real-time probing and most chains differed victim to victim: unauthenticated SQL injection in a login email parameter (error-based EXTRACTVALUE) read a one-time-passcode value in plaintext directly from an application database table, bypassing multi-factor authentication and reaching the admin panel; an image-upload field with no extension check then gave host remote code execution as a non-root user; a sudo misconfiguration allowing NOPASSWD execution of python3.12 escalated that to root; an internal NFS mount configured with no_root_squash let the agent read a separate host's WordPress database credentials in plaintext from its wp-config.php; those credentials gave a direct database write creating a new WordPress administrator account, which in turn let the agent upload a malicious plugin for code execution on the blog host; from there the agent dumped the full contents of the account's AWS Secrets Manager (46 secrets, 102 KB), reached the production Magento database on Amazon Aurora, extracted the Magento application's encryption key, and used it to decrypt stored card numbers encrypted with Blowfish in ECB mode. Confirmed impact across the campaign: 600,000-plus unexpired credit-card records exfiltrated from two victims, and skimmer scripts ordered against at least 27 named victims and confirmed in place on 19 of them according to the body of Gambit's report, although its own summary counts skimmer installations on the websites of five companies and does not reconcile the two figures. Gambit also detected more than 100 further websites infected with a skimmer associated with the campaign. Gambit reports some level of access to the assets of companies including a Fortune 500 hospitality company, a major US airline, a large private US industrial-supplies distributor and a US online fashion retailer, which it names separately from the illustrative chain above. A per-country cardholder breakdown embedded in Gambit's own page (488,372 of the recovered cards, 79.0%, United States) skews overwhelmingly toward the United States; no Swiss-issued cards appear among the top entries of that table (Gambit Security, 2026-09-22).
Gambit documents eight distinct skimmer-injection methods used across victims, all worth carrying into any custom-web-application hardening review: appending the loader to the end of a legitimate, already-served JavaScript file while restoring its original modification timestamp; inserting a foreign <script> tag directly into the checkout page; hiding the loader inside a site's Google global-site-tag (gtag.js) block, between the real gtag('js', ...) and gtag('config', ...) calls, padded with roughly a hundred tab characters to push it past the right edge of a typical code-review view; using a discovered AWS access key to write the loader into the storage bucket behind the retailer's own CDN, so it loads from that trusted CDN host rather than a third-party domain; injecting the loader into a database content field (such as a product-description column) through an admin pod and relocating it to a file on the victim's own domain; adding it to a production front-end deployment as a Kubernetes initContainer; writing it into the cached page model of the checkout page; and a self-healing cron job placed in a JBoss log directory that checks the injected file's size every two minutes and re-appends the loader whenever a redeploy reverts it. One of the Hermes agent's skill files, in a section titled "Database Wipe After Extraction", instructs the agent: "after extracting and downloading all card data, wipe the source fields in batches" (Gambit Security, 2026-09-22); at a second victim, a bicycle retailer, an overly broad table-name-matching cleanup step additionally dropped 180 staging and backup tables, including backups the victim's own administrators had separately made. This was collateral data loss from the attacker's own automated cleanup, not extortion. Some targets were not discovered by the agents at all: the operator handed at least two victims, a New Zealand retailer and a US photo printing company, to Hermes already holding a working administrator password, with the order to "get to work" (Gambit Security, 2026-09-22). OpenRouter's account balance recorded $7,005.71 spent over four weeks by 25 August, and Gambit extrapolates from the later volume of model calls that the full cost was likely between $12,000 and $18,000; "the operator’s own cost review gives a similar figure, a mean of $25.46 over 101 completed scans, from $3.13 for the cheapest target to $79.31 for the most expensive" (Gambit Security, 2026-09-22). Gambit states it "reached out to many of the affected organizations and took measures to take down the infrastructure discovered," crediting the Shadowserver Foundation, researcher Daniel Gordon, and other industry partners for their help notifying victims and taking down infrastructure (Gambit Security, 2026-09-22).
Detection concept, telemetry class first: in web-server access logs, alert on SQL-error-pattern responses (EXTRACTVALUE or equivalent) to login-form parameters, and on image-upload requests whose stored file is later executed by the web server rather than served as static content; in host telemetry, alert on sudo invocations of an interpreter (python3.12 or similar) by a low-privilege account with no corresponding change-management record; in network/mount telemetry, flag any host mounting an NFS export it has not mounted before, particularly where the export allows root-equivalent access; in cloud-audit telemetry, alert on a single principal enumerating or reading the entire contents of an AWS Secrets Manager instance in a short window; and in file-integrity or CDN-origin monitoring, treat any modification to a served JavaScript file's content (even with its timestamp preserved) or any script tag added to a checkout page outside a deployment window as high-priority. Triage: a legitimate deployment modifies checkout-page assets during a known release window with a corresponding commit and change record; the discriminators here are modification with no matching deployment event, a modification timestamp that has been deliberately restored to match the original file, or content padded with unusual whitespace specifically to evade a manual code read.
Hermes, the open-source NousResearch agent framework (Unit 42, 2026-07-30), has appeared in three earlier, unrelated intrusions: an operation against Thailand's Ministry of Finance that Hunt.io links with low-to-medium confidence to a Chinese-speaking operator (Hunt.io, 2026-07-23); a Taiwan government intrusion Tenable assesses as most likely a state-adjacent contractor or patriotic-hacker operation, with state sponsorship a close runner-up (Tenable, 2026-08-14); and a Zhuhai-based, Chinese-speaking operator's campaign against more than 460 targets, including persistent targeting of a Malaysian government entity (Unit 42, 2026-07-30). In three of the four intrusions the operators worked around model safety controls. In this campaign the operator added a skill to remove Hermes's own content-security filters (Gambit Security, 2026-09-22). In Taiwan the agents reframed the operation as "authorized penetration testing" (Tenable, 2026-08-14). In the Unit 42 case the actor likely turned to DeepSeek, which Unit 42 describes as a model with minimal safety controls, after Western providers' controls limited it, and a framework-bundled jailbreaking skill was also installed (Unit 42, 2026-07-30). That convergence, not any single victim in this campaign, is the transferable signal for a defender: an increasingly capable, freely available agent orchestration layer is now common tooling across financially motivated operators and government-targeting intrusions alike, regardless of how firmly any of them is ultimately attributed, and the underlying attack chain here (SQL injection, insecure OTP storage, unrestricted file upload, sudo misconfiguration, an over-permissive NFS export, and cloud-secrets exposure) is entirely composed of defects a Tier 2/3 team already reviews for in any custom-coded web application, Swiss public-sector portals included.
Between 10 and 15 September alone, 105 attack projects were launched and at least 27 companies were compromised to varying degrees.
the operator’s own cost review gives a similar figure, a mean of $25.46 over 101 completed scans, from $3.13 for the cheapest target to $79.31 for the most expensive
One of the Hermes agent’s skill files tells the agent to erase the card data from the victim’s Magento database once the data is stolen.
Anthropic identified and banned the account linked to the attacks. The attacker used an earlier Claude model, Opus 4.6, and attempts on newer Claude releases were rejected (Computing UK, 2026-09-23). Cloudflare separately confirmed it had shut down servers connected to the operation. Both actions had only marginal disruptive effect: "researchers said the attacker repeatedly rebuilt the infrastructure and continued the attacks" (Computing UK, 2026-09-23). For defenders, the reinforced lesson is that model-provider account bans and infrastructure takedowns are reactive controls with a short disruption window against a campaign whose own operator economics, a mean cost of $25.46 per target, make rebuilding after a takedown cheap; the underlying web-application defect classes this campaign walks through remain the more durable point of intervention.
Gambit's $12,000 to $18,000 spend is its own extrapolation from a $7,005.71 OpenRouter balance recorded on 25 August, not a billing total, and its report gives two skimmer counts: installations on the websites of five companies in its summary and confirmed skimmers on 19 of 27 named victims in its body (Gambit Security, 2026-09-22). For the Fortune 500 hospitality company, the US airline, the industrial-supplies distributor and the fashion retailer, Gambit reports some level of access to their assets, not compromise ranging from partial to full (Gambit Security, 2026-09-22). Operators worked around model safety controls in three of the four Hermes intrusions, not all of them, and in the Unit 42 case the reported route is the choice of a permissive model (Unit 42, 2026-07-30; Tenable, 2026-08-14).
Apply the R82.20 Security Hotfix or the appropriate Jumbo Hotfix Accumulator to every Check Point Security Management / Multi-Domain Security Management / Log / Multi-Domain Log / SmartEvent server now; no LivePatch exists for this issue.
On every affected server that was reachable on TCP/19009 while unpatched, check /etc/cron.d, authorized_keys, the startup paths and anything new under $FWDIR/conf/SMC_Files for unexpected changes, since the two log indicators miss the published exploit route.
Apply LivePatch Take 24 or the appropriate Jumbo Hotfix Accumulator to every Check Point Security Gateway, Security Management Server and Spark Firewall now, including management servers with no VPN configured, which Check Point states are vulnerable regardless of configuration; if the offline LivePatch package was used on R82.10 JHF Take 24 or lower / R82 JHF Take 107 or lower / R81.20 JHF Take 146 or lower, also install the hardened Take 26; the locally managed Spark Firewall has no workaround short of patching.
Review Mobile Access logs for anomalous certificate-based logins and any follow-on internal port/service scanning from suspicious Mobile Access sessions on every Spark Firewall, whether or not it has already been patched.
Patch every self-managed Virtualizor installation to 3.2.9 patch 9 or 3.3.0 now, and keep admin-panel ports 4084/4085 off the public internet or behind an allowlist regardless of patch level.

Verification & coverage notes
8 new entries, 2 updates, 1 deep dive. All three CISA KEV additions this run's mechanical sweep found without existing coverage (CVE-2026-93616, CVE-2026-93952, CVE-2026-94127) were published as new critical entries; a fourth in-window KEV addition, CVE-2026-85102, was already covered and shipped as an update record elevating that entry to critical. One parallel research task's first attempt was terminated mid-flight by a content-safety classifier reacting to raw advisory text (a known false-positive pattern); a retry with clearer defensive framing succeeded cleanly.
Duration note: this run's total elapsed time (~3.2 h) exceeds the usual range. The cause is the verification loop itself, not a stall: eight successive verification passes each found genuine, fixable defects (an inconsistent attribution hedge, an uncited detail, an overstated exploit-availability claim, unlinked entity references, a missing CISA KEV cross-reference, among others) and every finding across all eight iterations was remediated in place before the next pass or before publish; none was left unfixed. The loop reached its 8-iteration cap without achieving the double-CLEAN confirmation and published fail-open per the cap rule; verification_residual_count (2) is the capped final iteration's own truth+editorial tally at the moment it ran, logged for the audit trail as the rules require; it is not a count of unresolved content, since that iteration's findings were also fixed before this commit.
Correction:2026-09-06/mikrotik-routeros-mikrotrick-ssh-auth-bypass-privesc-chain; CERT Polska's own 2026-09-22 technical write-up states plainly that CVE-2026-67276 was wrongly associated with the actively-exploited MikroTrick chain in earlier reporting (including this entry's own original text, which quoted CERT Polska's 2026-09-05 post describing it as the signature-forgery entry point). The real entry point is CVE-2026-67279 (SSH rekey-during-authentication state confusion). Corrected title, summary, both CVEs' exploitation status, and the body's mechanism description; does not float the entry (a correction, not a new development).
Deep dive:2026-09-23/gambit-ai-agent-retail-skimmer-campaign-strix-cairn-hermes. Selected over the three same-day critical CVEs, which are single-flaw vendor disclosures already carrying full vendor-supplied detection guidance and did not need extended kill-chain treatment; this finding instead offered a substantive, fully-reconstructed multi-stage attack chain. Two claims from the corroborating secondary outlet were excluded from the entry because they do not appear in the primary research: a claim naming an additional AI model in the harness stack, and a payment-processor fraud-flag statistic. Specific attacker domains, a file hash and IP addresses present in the primary research were not reproduced, consistent with this pipeline's no-IOC policy.
Note on CVE-2026-93952 (Arista VeloCloud Orchestrator): the vendor advisory's indicator-of-compromise section (file paths, a file hash, two IP addresses) was not reproduced, consistent with the no-IOC policy.
Contradiction: Gambit Security's own primary research states two different counts for how many websites carried a live skimmer ("five" in its opening summary and "19 of 27" in its dedicated results section) without reconciling them. The retail-skimmer campaign entry uses the larger, more precise, dedicated-section figure (19 of 27), which a second outlet's reporting also uses independently.
Coverage backlog (the queue of previously-surfaced items awaiting corroboration): all 9 open items were re-checked; no material change on 8 of them. One item (a Bern hospital group's ServiceNow migration delay, sourced to a single paywalled article) is recommended for closure as unresolvable: over 20 consecutive daily checks since 2026-08-30 have hit the identical access block with zero independent corroboration found anywhere; it can be reopened if the article or a corroborating source becomes reachable.
Dropped as out of scope: a Bavarian university's disclosure of a roughly 52,000-record data exfiltration, no Swiss nexus, and no source names a mechanism or actor, so the finding could not carry an evidence-bound technique mapping; noted for awareness only, since several structurally identical items are already in the backlog. Also dropped: a leak-site defacement in an inter-gang extortion feud, genuinely fresh, but with no victim-facing technique, no constituency nexus and no detection lever.
Single-source entries:2026-09-23/ncsc-ch-google-recovery-oauth-app-password-persistence (the national-CERT carve-out, NCSC Switzerland's own weekly advisory). 2026-09-23/gambit-ai-agent-retail-skimmer-campaign-strix-cairn-hermes (the research vendor is the sole technical assessor; the corroborating outlet reports on those findings rather than independently assessing the campaign). 2026-09-23/virtualizor-billing-hook-unauth-root-rce (the discovering researcher is also the CVE-assigning authority; no independent second analysis has been published yet).
Fetch gap: F5's own advisory (my.f5.com K000162605) is a client-rendered SPA unreachable via extract or jina (loading-shell only on both transports); covered via CERT-EU's Security Advisory 2026-013 (national-CERT-class primary quoting F5 directly) plus two independent secondaries quoting the same text.
Watchlist: products checked=0, hits=0; suppliers checked=0, hits=0, no product or supplier watchlist configured this deployment.
Coverage gaps: cert-at (403 on both attempted URLs, no working alternate found this run); dcod-ch (homepage is a static dashboard, not an article listing); csa-labs and paradigm-shift-research (both republish disclosures 3–7 days old under a fresh display date; recommend future runs treat their displayed date as a republish timestamp, not a recency signal, and always verify against the linked primary).
