Malicious npm Packages Deploy Multi-Stage Trojan with Embedded GitLab Keys

Positive Technologies researchers uncovered a campaign in which an attacker published multiple trojanized packages to the npm registry under the accounts alex05255, mdrafiqulislamrabby, b.w1001, abdev8773 and mollspotwood54400. The affected packages include svg-fetcher, tradepilot, polytrade, polymarket-kit, react-svg-chunk, gamified-trading-system, font-huge, font-hub, mdb-vite, router-processor and route-processor. Each package concatenates several constants to build a C2 URL, downloads the next stage identified as token versions 106, 107, 108 and 116, and sends the hardcoded value logo in the bearrtoken header. Later stages contain heavily obfuscated JavaScript that collects username, hostname and operating-system information before establishing a WebSocket channel for command execution. Releases 106 and 116 also embed a public-private key pair belonging to a private GitLab instance operated by the threat actor, suggesting the use of CI/CD pipelines for code obfuscation and stage generation. The findings highlight the continued risk of supply-chain attacks through popular open-source repositories and the value of automated package monitoring.
