MemOSPYSEC-2026-3987
MemoryOS 2.0.34 was published with a credential-stealing binary
No fix yet
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.
