    Details: Source: kam193 (57c6acfcb3c6bb659cac9b311e2cc25e72f3ab57d80e3403b70b7e05a2a06ed9) On installation or importing, the package attempts to exfiltrate some basic information, e.g. /etc/passwd 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: 2025-06-atlasctf Reasons (based on the campaign): - exfiltration-generic - 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.
