    Details: Source: kam193 (ffe859775c26074cc4af620ba898f558fb64310ff0cd6ac1cb212700fadcb182) 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.
