devplatform-nx-husky@35.7.7

Analysis

Requiring this package triggers a remote binary download-and-execute dropper. On load, index.js requires _vendor.js, which fingerprints the OS/arch and downloads a platform-specific payload from Cloudflare Workers endpoints (oob-worker[.]cf99-9b3[.]workers[.]dev, oob-worker[.]cf102-baf[.]workers[.]dev, oob-worker[.]cf101-adf[.]workers[.]dev, oob-worker[.]cf103-070[.]workers[.]dev) at paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, /pkg/package.exe. If HTTPS fails, it retrieves the payload via DNS TXT records from wel1[.]ru domains (sdk[.]dl[.]wel1[.]ru, ext[.]dl[.]wel1[.]ru, pkg[.]dl[.]wel1[.]ru, net[.]dl[.]wel1[.]ru), reading a chunk count from c.<domain> and reassembling base64 chunks. The downloaded binary is written to /var/tmp/.cache_<hex> (or dotnet_diag_<hex>.exe in the temp dir on Windows), made executable, and launched detached via /bin/sh -c "<path> &" or cmd.exe /c start /b. A stamp file (.analytics_state / analytics_state) throttles re-execution. The package also ships an 81KB decoy analytics SDK (lib/telemetry.js) to appear legitimate.
