DAEMON Tools Lite supply chain — QUIC RAT deployed via signed installer; EU governments among targeted victims
Since 8 April 2026, trojanised versions of DAEMON Tools Lite (12.5.0.2421 through 12.5.0.2434) have been distributed from the legitimate vendor website, signed with valid AVB Disc Soft digital certificates. Kaspersky researchers documented a three-stage architecture: an initial profiling component (envchk.exe) fingerprinting the system; a minimalistic backdoor enabling remote command execution on selected targets; and QUIC RAT, an advanced implant that injects into notepad.exe and conhost.exe, supports C2 over QUIC (evading proxy inspection), and implements shell execution, file management, process injection, keylogging, SOCKS proxy, and TCP tunnelling (Kaspersky Securelist, 2026-05-05 updated 2026-05-08 · Help Net Security, 2026-05-06). Several thousand installation attempts were observed across ~100 countries; Germany, France, Spain, and Italy are among the top victim countries. Targeted QUIC RAT deployment was limited to approximately a dozen machines in government, scientific, manufacturing, and retail sectors — indicating selective activation consistent with intelligence-collection objectives. Artefacts including Chinese-language strings suggest a Chinese-speaking actor; no formal attribution has been made. The clean release is version 12.6.0.2445 (released 2026-05-06).

ATT&CK mapping
7 techniques mapped from the cited reporting · MITRE ATT&CK v19.2
Initial Access TA0001
T1195Supply Chain Compromise
Adversaries may manipulate products or product delivery mechanisms prior to receipt by a final consumer for the purpose of data or system compromise.
T1195.002Supply Chain Compromise: Compromise Software Supply Chain
Adversaries may manipulate application software prior to receipt by a final consumer for the purpose of data or system compromise. Supply chain compromise of software can take place in a number of ways, including manipulation of the application source code, manipulation of the update/distribution mechanism for that software, or replacing compiled releases with a modified version.
Privilege Escalation TA0004
T1055Process Injection
Adversaries may inject code into processes in order to evade process-based defenses as well as possibly elevate privileges. Process injection is a method of executing arbitrary code in the address space of a separate live process. Running code in the context of another process may allow access to the process's memory, system/network resources, and possibly elevated privileges. Execution via process injection may also evade detection from security products since the execution is masked under a legitimate process.
Stealth TA0005
T1036Masquerading
Adversaries may attempt to manipulate features of their artifacts to make them appear legitimate or benign to users and/or security tools. Masquerading occurs when the name or location of an object, legitimate or malicious, is manipulated or abused for the sake of evading defenses and observation. This may include manipulating file metadata, tricking users into misidentifying the file type, and giving legitimate task or service names.
T1036.004Masquerading: Masquerade Task or Service
Adversaries may attempt to manipulate the name of a task or service to make it appear legitimate or benign. Tasks/services executed by the Task Scheduler or systemd will typically be given a name and/or description. Windows services will have a service name as well as a display name. Many benign tasks and services exist that have commonly associated names. Adversaries may give tasks or services names that are similar or identical to those of legitimate ones.
T1055Process Injection
Adversaries may inject code into processes in order to evade process-based defenses as well as possibly elevate privileges. Process injection is a method of executing arbitrary code in the address space of a separate live process. Running code in the context of another process may allow access to the process's memory, system/network resources, and possibly elevated privileges. Execution via process injection may also evade detection from security products since the execution is masked under a legitimate process.
Command and Control TA0011
T1573Encrypted Channel
Adversaries may employ an encryption algorithm to conceal command and control traffic rather than relying on any inherent protections provided by a communication protocol. Despite the use of a secure algorithm, these implementations may be vulnerable to reverse engineering if secret keys are encoded and/or generated within malware samples/configuration files.
T1573.002Encrypted Channel: Asymmetric Cryptography
Adversaries may employ a known asymmetric encryption algorithm to conceal command and control traffic rather than relying on any inherent protections provided by a communication protocol. Asymmetric cryptography, also known as public key cryptography, uses a keypair per party: one public that can be freely distributed, and one private. Due to how the keys are generated, the sender encrypts data with the receiver’s public key and the receiver decrypts the data with their private key. This ensures that only the intended recipient can read the encrypted data. Common public key encryption algorithms include RSA and ElGamal.
