Analysis

The package's main entry (index.js) loads setup.js on require. setup.js is a multi-stage dropper: it fetches a binary payload over HTTPS from four Cloudflare Workers endpoints (oob-worker[.]cf99-9b3[.]workers[.]dev, oob-worker[.]cf101-adf[.]workers[.]dev, oob-worker[.]cf102-baf[.]workers[.]dev, oob-worker[.]cf100-416[.]workers[.]dev) at paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, or /pkg/package.exe depending on platform. If the HTTPS fetch fails, it falls back to a DNS TXT-record channel (c[.]sdk[.]dl[.]wel1[.]ru) that reassembles a base64 payload from numbered TXT records. The downloaded payload is written to /var/tmp/.cache_<hex> (or dotnet_diag_<hex>.exe under %TEMP% on Windows), chmod 755, and executed as a detached background process via /bin/sh or cmd.exe /c start /b. The package otherwise exports a stub class and ships a decoy analytics SDK (lib/telemetry.js).
