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 downloaded bytes are written to /tmp or %TEMP% under a disguised name (.cache_\u003chex\u003e on Unix, dotnet_diag_\u003chex\u003e.exe on Windows), chmod'd 0755, and spawned detached via /bin/sh -c '\u003cpath\u003e \u0026' or cmd.exe /c start /b, with.unref() to survive the parent process. bootstrap() honors DISABLE_TELEMETRY / ANALYTICS_OPT_OUT / DO_NOT_TRACK and writes a.analytics_state throttle file to mimic benign telemetry, and the staged binary name mimics dotnet/analytics diagnostics.
