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.

There is no hash check, signature verification, or version pinning, and the host is unrelated to any package publisher. The library surface is a thin decoy: __init__.py forwards all attribute access to the `requests` module and the README advertises 'A simple request cloner for Python', providing cover for the install-time dropper. The drop path uses a self-incriminating directory name (C:\\MALWARE_DELETE) and the response carries application/vnd.microsoft.portable-executable, confirming hostile intent.
