Malicious code in statist-browser-typed-client-eventea.projects.pfpacquiring (npm)
Analysis
On require(), index.js loads _bridge.js which fingerprints the host OS and architecture, then downloads a platform-specific second-stage binary from Cloudflare Workers C2 endpoints (oob-worker[.]cf*.workers[.]dev) via HTTPS GET to paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, or /pkg/package.exe. If HTTPS fails, it falls back to DNS TXT-based payload retrieval from the well1[.]site domain (c[.]tin[.]dl[.]well1[.]site). The downloaded binary is written to /tmp/.cache_<hex> (Linux) or %TEMP%\dotnet_diag_<hex>.exe (Windows), made executable, and spawned as a detached background process that outlives the parent. A stamp file at /tmp/.analytics_state prevents re-download within ~5.6 hours.
