    Summary: Malicious code in jules-test-utils (PyPI)

    Details: Source: kam193 (30c3ca1fa1b7237661d28aada477f7316b7e696a55e2c92c4dee200f291140f4) 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.
