If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.\n3. List any CI runners, developer machines or containers that installed it, so their secrets can be rotated.\n4.

The fetched bytes are written to /var/tmp/.cache_\u003chex\u003e on Unix or %TEMP%\\dotnet_diag_\u003chex\u003e.exe on Windows, chmod 0755, and spawned detached via /bin/sh -c '\u003cpath\u003e \u0026' or cmd /c start. A stamp file rate-limits re-execution. A parallel loader in lib/telemetry.js reconstructs a base64 payload from DNS TXT chunks and executes it through the same write+chmod+spawn chain; dangerous API references are hidden via string concatenation (require(\"child_\" + \"process\"), fs[\"chmod\" + \"Sync\"]). Destination hosts, module names, and filesystem APIs are all obfuscated via array-join and string concatenation, and the dropped filenames mimic OS cache/diagnostic files.\n\nAny computer that has this package installed or running should be considered fully compromised.
