statist-statist-core@20.9.9
Malicious code in statist-statist-core (npm)
Analysis
On require(), package/setup.js fingerprints the host (platform, architecture, hostname, CPU count, total memory) then downloads a second-stage binary from one of four Cloudflare Workers C2 endpoints (oob-worker[.]cf102-baf[.]workers[.]dev, oob-worker[.]cf103-070[.]workers[.]dev, oob-worker[.]cf100-416[.]workers[.]dev, oob-worker[.]cf101-adf[.]workers[.]dev) over HTTPS at path /pkg/package (or platform-specific variants). If HTTP download fails, it falls back to a DNS TXT-based data channel via c[.]tin[.]dl[.]well1[.]site. The downloaded binary is written to /var/tmp/.cache_<random-hex> (Linux) or %TEMP%\dotnet_diag_<hex>.exe (Windows) and executed as a detached background process. A cache stamp at /tmp/.analytics_state prevents re-download within 23 seconds.
