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 channel is a purpose-built covert DNS tunnel that bypasses HTTP egress controls; errors are swallowed in silent try/catch blocks. The destination is unrelated to the package's declared purpose of providing build configuration, and the 'telemetry' naming plus hardcoded encryption key are cover-story shaping around identity exfiltration.\n\nAny computer that has this package installed or running should be considered fully compromised.
