Threats Tagged 'fake job interview'

Jamf Threat Labs discovered a cluster of 14 trojanized macOS applications distributed as DMG and PKG files impersonating legitimate software like The Unarchiver, Sketch, and Bartender. These samples are linked to the Contagious Interview campaign, a DPRK-attributed operation using fake job interviews as a pretext. The malware chain begins with unsigned, modified applications containing hidden executables that download staging scripts from infrastructure at 162.0.239[.]85. The attack progresses through multiple stages, ultimately deploying OtterCookie malware, which provides remote access capabilities, credential stealing from browsers and crypto wallets, filesystem scanning, and clipboard monitoring. The delivery method represents an evolution from previous Git hook and VS Code task-based attacks to standalone installer packages requiring manual quarantine attribute removal to execute.

Void Dokkaebi, also known as Famous Chollima, has evolved its operations into a self-propagating supply chain threat targeting software developers. The North Korea-aligned group uses fabricated job interviews to lure developers into cloning malicious repositories. Once compromised, the victim's machine becomes an infection vector through two mechanisms: malicious VS Code task configurations that execute automatically when workspaces are opened, and active injection of obfuscated JavaScript into source code files with Git history tampering to conceal modifications. This creates a worm-like propagation chain where each compromised developer seeds new repositories with infection vectors. Analysis in March 2026 identified over 750 infected repositories, with contamination reaching organizations including DataStax and Neutralinojs. The campaign delivers payloads via blockchain infrastructure including Tron, Aptos, and Binance Smart Chain, deploying variants of DEV#POPPER RAT and other tools to steal cryptocurre...
