The incident that flagged it

High11 Feb 2026

Lazarus "graphalgo" fake-recruiter campaign (npm + PyPI)

ReversingLabs attributed an ongoing fake-recruiter campaign (active since May 2025, reported Feb 2026) to North Korea's Lazarus Group (overlapping Jade Sleet / UNC4899). Crypto, JavaScript, and Python developers are lured via LinkedIn/Reddit/Facebook into interview "coding tasks" that pull a token-protected RAT loader from npm and PyPI. ~192 malicious packages attributed in total; bigmathutils alone passed 10,000 downloads.

Versions named here: 3.5.1rc0.dev0, 3.5.2, 3.5.3, 3.5.5, 3.5.6

What to do if you installed one of these

Treat the machine as compromised rather than simply upgrading. Packages in these incidents typically execute at install time, so the payload has already run with whatever credentials were in the environment.

1.Rotate every credential that machine or CI job could reach - registry tokens, cloud keys, SSH keys, CI secrets - from a different machine.
2.Pin to a version not listed above, then reinstall from a clean lockfile.
3.Clear caches and private mirrors. Artifactory, Nexus, Verdaccio, and devpi routinely keep serving a tarball after the public registry has pulled it.
4.Read the incident write-up above - recommended actions differ per incident, and some have specific indicators of compromise worth grepping your logs for.

Check your whole project

graphalgo-py is one of many packages in these incidents, and it is usually pulled in as a transitive dependency rather than one you installed directly. Paste your requirements.txt to check every dependency at once - it runs in your browser and nothing is uploaded.
