If this package is installed
Remove it, treat the machine (or CI runner) as compromised, and rotate every secret, token and key it could access — from a different, clean machine.

index.js unconditionally requires./_bridge on module load. _bridge.js selects an OS/arch-specific payload URL from string-array-concatenated hostnames (oob-worker.cf101-adf.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf99-9b3.workers.dev), downloads a binary over HTTPS with a DNS TXT chunked-base64 fallback via *.dl.well1.site, writes it to /var/tmp or %TEMP% under a disguised name (dotnet_diag_<hex>.exe /.cache_<hex>), chmods it 0755, and detached-spawns it via /bin/sh -c "<path> &" or cmd.exe /c start /b. No hash or signature verification. Destination hostnames are assembled at runtime by joining split string arrays to evade static analysis, and a written state file plus environment-variable opt-outs (DISABLE_TELEMETRY, ANALYTICS_OPT_OUT, DO_NOT_TRACK) and comments referencing "SHA-256 integrity check" and "session tracking" frame the drop as telemetry, which does not match the package's stated Operations SDK purpose.
