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 package is advertised as a chat-messages interface and has no legitimate need to fetch and execute a platform-specific binary from anonymized hosts at load time. The string-split obfuscation of the destination hostnames, the diagnostics-masquerading filenames, and the detached spawn are consistent with a hostile import-time dropper.\n\nAny computer that has this package installed or running should be considered fully compromised.
