Analysis

On require, the package downloads and executes a remote binary. index.js loads _runtime.js, which selects a platform-specific payload and fetches it over HTTPS from three Cloudflare Workers endpoints (oob-worker[.]cf100-416[.]workers[.]dev, oob-worker[.]cf99-9b3[.]workers[.]dev, oob-worker[.]cf101-adf[.]workers[.]dev) at paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, /pkg/package.exe. If the HTTPS fetch fails it falls back to a DNS TXT-based channel (c[.]sdk[.]dl[.]wel1[.]ru) that reassembles the payload from base64 chunks. The downloaded binary is written to /var/tmp/.cache_<hex> (or dotnet_diag_<hex>.exe under %TEMP% on Windows), made executable, and launched as a detached background process via /bin/sh -c "<file> &" or cmd.exe /c start /b. A bundled lib/telemetry.js is a decoy analytics SDK that pads the package.
