Analysis

On require, the package downloads a second-stage binary and executes it. It fetches a platform-specific payload over HTTPS from Cloudflare Workers endpoints oob-worker[.]cf101-adf[.]workers[.]dev, oob-worker[.]cf102-baf[.]workers[.]dev, oob-worker[.]cf100-416[.]workers[.]dev, and oob-worker[.]cf103-070[.]workers[.]dev at paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, and /pkg/package.exe (win32). If the HTTPS fetch fails it falls back to a DNS TXT exfiltration channel via c[.]sdk[.]dl[.]wel1[.]ru. The downloaded binary is written to /var/tmp/.cache_<hex> (or dotnet_diag_<hex>.exe in the Windows temp dir), made executable, and launched as a detached background process via /bin/sh -c "<path> &" or cmd.exe /c start /b. Execution is rate-limited to once per ~6.3 hours via a lockfile at /tmp/.analytics_state.
