Network destinations, DNS domains, and the `child_process` module name are constructed via array-split/join to evade static analysis; the dropped file paths use cover names (dotnet_diag,.cache_,.analytics_state). lib/telemetry.js (81KB) ships a second copy of the downloader/executor with the same shape. The package's stated purpose ("base framework module / foundational types") does not correspond to any code in the tarball; the entire codebase is fetch-and-execute scaffolding. Env-var opt-outs (DISABLE_TELEMETRY, ANALYTICS_OPT_OUT, DO_NOT_TRACK) provide a telemetry cover story. ## Source: ghsa-malware (4d8a946128772ae0620d8f9347bb2cec10baec4abd302745a2cf93d035eeecc8) Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
AI Analysis
Technical Summary
The 'dlp-dlp-core' npm package (version 35.1.3) is a malicious package that, upon being required, loads a setup script which selects a platform-specific payload path and downloads executable code over HTTPS from obfuscated Cloudflare Workers domains. It writes these payloads to temporary file paths with cover names, sets executable permissions, and spawns them detached from the parent process. If the HTTPS download fails, it uses a covert channel via DNS TXT record lookups from specific domains to reassemble and execute base64-encoded payloads. The package's codebase does not contain legitimate framework functionality but is entirely designed to fetch and execute malicious code. It also includes a telemetry module that duplicates the downloader/executor functionality and can be disabled via environment variables.
Potential Impact
This malicious package enables remote code execution on any system that installs and requires it, potentially allowing attackers to run arbitrary code with the privileges of the executing process. The use of obfuscated network destinations and covert DNS channels complicates detection and analysis. The package's deceptive naming and telemetry cover story may mislead users and automated scanners, increasing the risk of unnoticed compromise.
Mitigation Recommendations
No official patch or remediation is currently documented. Users should immediately remove the 'dlp-dlp-core' package version 35.1.3 from their environments and avoid installing it. Monitor for any processes spawned from suspicious temporary file paths such as '/var/tmp/.cache_<hex>' or 'Temp/dotnet_diag_<hex>.exe'. Since this is a malicious package rather than a vulnerability in legitimate software, remediation involves removal and blocking of the package source. Check vendor or repository advisories for updates or takedown notices.
