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.

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

sysdiagd is a malicious PyPI package that codelake Research independently detected during automated supply-chain scanning, corroborated by MAL-2026-17861 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 drops and launches a secondary native payload.

Affected version(s): 1.2.2.

How we found it

codelake's per-ecosystem scanners flagged the specimen and the AI-triage judge classified it malicious (recorded signal: native-binary dropper (src/sysdiagd/__main__.py:261), confidence 0.90).

This is an independent detection by codelake's own scanners and AI-triage pipeline; it is corroborated by MAL-2026-17861 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 sysdiagd immediately from any project, lockfile or CI image that references it, and reject the affected versions (1.2.2). Act
02 Cross-reference the corroborating OSV record(s) MAL-2026-17861 for the authoritative version range and indicators. Verify

Detected independently by codelake Research · automated per-ecosystem supply-chain scanning + AI-triage, verified at the indicator level on extracted source (no execution). Corroborated by MAL-2026-17861 in OSV. codelake stores only the detection rule, indicators and analysis, never raw payloads.
