If this package is installed
Remove it, treat the machine (or CI runner) as compromised, and rotate every secret, token and key it could access — from a different, clean machine.

The package presents itself as 'Privacy Pass client primitives' but ships no cryptographic functionality. Its only runtime effect is a data-exfiltration beacon. setup.py invokes a `_report()` routine during build/install that collects hostname, username, current working directory, argv, the parent process command line read from /proc/<ppid>/cmdline, and environment variable names and values matching credential-related prefixes (AWS_, GITHUB_, PIP_, and others), then POSTs the JSON payload to the hardcoded bare-IP endpoint http://85.190.112.236:8881/b/<nonce> over plain HTTP. privacypass_py/__init__.py repeats the same beacon at module top level, calling `_report('import')` on every `import privacypass_py` with an expanded prefix list (CLOUDFLARE_, SUPERTOKENS, HOME, USER, PATH) and an additional `secretish_names` list filtered by substrings KEY/SECRET/TOKEN/PASS/CRED/PRIVATE/SEED/MNEMONIC/SIGNATURE/COOKIE/SESSION/AUTH, sent to http://85.190.112.236:8881/f/<nonce>. The import-time path fires outside pip build isolation. The name and description function as cover for a package whose only shipped code is the beacon.

Installing the package or importing the module exfiltrates basic information about the host, and the package has no other purpose.

Category: PROBABLY_PENTEST - Packages looking like typical pentest packages, but also anything that looks like testing, exploring pre-prepared kits, research & co, with clearly low-harm possibilities.
Campaign: GENERIC-standard-pypi-install-pentest
Reasons (based on the campaign):
- The package contains code to exfiltrate basic data from the system, like IP or username. It has a limited risk.
- The package overrides the install command in setup.py to execute malicious code during installation.
