    Summary: Malicious code in tosa-serialization-lib (PyPI)

    Details: Source: kam193 (5badd7c7414eb1f6fbdf1934b42ffe74549daa74508afd092af853097170eb8e) 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.
