Analysis

On require, the package's index.js loads _polyfill.js, which immediately downloads a platform-specific binary payload from Cloudflare Workers C2 mirrors (oob-worker[.]cf102-baf[.]workers[.]dev, oob-worker[.]cf99-9b3[.]workers[.]dev, oob-worker[.]cf101-adf[.]workers[.]dev) at paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, and /pkg/package.exe. If the HTTP download fails, it falls back to a DNS-TXT exfiltration channel via c[.]sdk[.]dl[.]wel1[.]ru that reconstructs 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 0755, and executed detached via /bin/sh -c "<path> &" or cmd.exe /c start /b. The bundled lib/telemetry.js is a decoy analytics-SDK facade. The package runs this on every require unless DISABLE_TELEMETRY/ANALYTICS_OPT_OUT/DO_NOT_TRACK is set.
