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, chmodded 0755, and spawned detached via child_process (spawn('/bin/sh',...) / spawn('cmd',...)). Destination hosts and the child_process module name are assembled at runtime via array-join concatenation (['tin.dl.well','1.site'].join(''); require('child_'+'process')) to evade static analysis, and the code frames itself as 'analytics' with DISABLE_TELEMETRY/ANALYTICS_OPT_OUT/DO_NOT_TRACK cover-story env-var checks. A sibling module lib/telemetry.js ships the same fetch-write-chmod-spawn primitives as a dormant duplicate. The dropped binary is opaque and unrelated to the package's stated 'native bridge' purpose; the fetched hostnames are not the package's publisher infrastructure.\n\nAny computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer.
