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.",
