Initial Access TA0001

T1195.001Supply Chain Compromise: Compromise Software Dependencies and Development Tools×1

Adversaries may manipulate software dependencies and development tools prior to receipt by a final consumer for the purpose of data or system compromise. Applications often depend on external software to function properly. Popular open source projects that are used as dependencies in many applications, such as pip and NPM packages, may be targeted as a means to add malicious code to users of the dependency. This may also include abandoned packages, which in some cases could be re-registered by threat actors after being removed by adversaries. Adversaries may also employ "typosquatting" or name-confusion by choosing names similar to existing popular libraries or packages in order to deceive a user.

T1566.002Phishing: Spearphishing Link×1

Adversaries may send spearphishing emails with a malicious link in an attempt to gain access to victim systems. Spearphishing with a link is a specific variant of spearphishing. It is different from other forms of spearphishing in that it employs the use of links to download malware contained in email, instead of attaching malicious files to the email itself, to avoid defenses that may inspect email attachments. Spearphishing may also involve social engineering techniques, such as posing as a trusted source.

Execution TA0002

T1059.004Command and Scripting Interpreter: Unix Shell×1

Adversaries may abuse Unix shell commands and scripts for execution. Unix shells are the primary command prompt on Linux, macOS, and ESXi systems, though many variations of the Unix shell exist (e.g. sh, ash, bash, zsh, etc.) depending on the specific OS or distribution. Unix shells can control every aspect of a system, with certain commands requiring elevated privileges.

Credential Access TA0006

T1555.003Credentials from Password Stores: Credentials from Web Browsers×1

Adversaries may acquire credentials from web browsers by reading files specific to the target browser. Web browsers commonly save credentials such as website usernames and passwords so that they do not need to be entered manually in the future. Web browsers typically store the credentials in an encrypted format within a credential store; however, methods exist to extract plaintext credentials from web browsers.

DPRK UNK_DeadDrop weaponises VS Code / Cursor auto-run to hit developers, including EU targets

Proofpoint details UNK_DeadDrop, a North-Korea-aligned cluster (related to but distinct from Contagious Interview / Famous Chollima) that sent 250+ recruitment-themed phishing emails to ~100 finance, crypto, education and technology organisations over April–May 2026 (Proofpoint, 2026-06-15); the targeted geographies are a US majority followed by the UK, Australia, France, Germany and the Netherlands, among others (The Hacker News, 2026-06-16). The lure links to attacker-controlled GitHub/GitLab repositories carrying a .vscode/tasks.json with runOn: folderOpen; VS Code shows a workspace-trust prompt, but Cursor IDE executes the task silently with no prompt, dropping the open-source Overlord Go C2 that steals browser credentials and crypto wallets (The Hacker News, 2026-06-16). Mapped to T1566.002, T1195.001, T1059.004 and T1555.003.

Why it matters to us: public-sector and fintech development teams that have adopted Cursor are exposed to silent execution on repository open. Hunt for editor processes (code, cursor) spawning shell/script interpreters outside build directories (Sysmon EID 1 parent-image filter); enforce workspace-trust policy and restrict VSIX installation to an approved-publisher allowlist via enterprise policy.
