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.

## Source: ossf-package-analysis (55332d91b2afbf62923f1d853c6df3a5c8f768797a3176effdecba07b91d4fbf)
The OpenSSF Package Analysis project identified 'vinted-mocked-apis' @ 99.0.0 (pypi) as malicious.

It is considered malicious because:

- The package communicates with a domain associated with malicious activity.
