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.

idnna — malicious PyPI package, independently detected and OSV-corroborated

idnna is a malicious PyPI package that codelake Research independently detected during automated supply-chain scanning, corroborated by MAL-2026-13488 in OSV. The detection signal and affected versions are detailed below.

CriticalIndependent detectionOSV-corroborated
Summary

codelake's analysis classifies the detection signal as behaviour that downloads and executes remote code.

Affected version(s): 0.1.1, 0.1.2, 0.2.0, 0.3.0.

How we found it

codelake's per-ecosystem scanners flagged the specimen and the AI-triage judge classified it malicious (recorded signal: Remote fetch-then-exec via urllib.request.urlretrieve, confidence 0.95).

This is an independent detection by codelake's own scanners and AI-triage pipeline; it is corroborated by MAL-2026-13488 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.

Response & guidance
#ActionPriority
01 Remove idnna immediately from any project, lockfile or CI image that references it, and reject the affected versions (0.1.1, 0.1.2, 0.2.0, 0.3.0). Act
02 Cross-reference the corroborating OSV record(s) MAL-2026-13488 for the authoritative version range and indicators. Verify
