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 payload is written under /var/tmp or %TEMP% with a disguised name (.cache_\u003crand\u003e on Unix, dotnet_diag_\u003crand\u003e.exe on Windows), chmod +x, and spawned detached via cp.spawn(\"/bin/sh\", [\"-c\", fp + \" \u0026\"], {detached:true}).unref() or spawn(\"cmd\",...).
