    Summary: Malicious code in lm-sys (PyPI)

    Details: Source: kam193 (69240e51e47ad6f05a6d2e98047b80c3beb9f2e05d1449b50606c812b9eb1c1e) 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.
