Malware Advisory Detected 2026-10-20 · codelake independent detection
Malware — published immediately. Confirmed supply-chain malware is public at publish time and reported concurrently to the affected registry and the OpenSSF malicious-packages database. There is no coordinated-disclosure window (the maintainer is the attacker). codelake never stores raw payloads — only the detection rule, file:line, and IOCs.

vuln-package — malicious npm package, independently detected and OSV-corroborated

vuln-package is a malicious npm package that codelake Research independently detected during automated supply-chain scanning, corroborated by MAL-2026-10212 in OSV. The detection signal and affected versions are detailed below.

HighIndependent detectionOSV-corroborated
Summary

codelake's analysis classifies the detection signal as behaviour that executes attacker code automatically at install time (npm/pip install hook).

Affected version(s): 99.9.14.

How we found it

codelake's per-ecosystem scanners flagged the specimen and the AI-triage judge classified it malicious (recorded signal: preinstall hook executes bundled script, confidence 0.90).

This is an independent detection by codelake's own scanners and AI-triage pipeline; it is corroborated by MAL-2026-10212 in OSV (codelake was not necessarily the first public reporter for this record).

All analysis is performed at the indicator level on extracted source only — codelake never executes specimens and stores only the detection rule, indicators and analysis, never raw payloads.
