MemoryOS 2.0.34 was published with a credential-stealing binary

MemOS

Published Sep 23, 2026

Unrated
No fix yet
Source advisory

An attacker with write access to the GitHub repository pushed malicious

commits and tagged v2.0.34, and the project's own GitHub Actions release

workflow built and uploaded 2.0.34 to PyPI.

Importing the package runs memos/_stage0.py, which launches

a bundled sckit binary that collects credentials

(.pypirc, .npmrc, .git-credentials, SSH keys, token-like environment variables)

and sends them to *.skyleen[.]fr.

Remove 2.0.34 and rotate any credentials reachable from affected machines.
