--- _-= Per source details. Do not edit below this line.=-_ ## Source: kam193 (ab2e307770a6b144edad3254d316375ed3cdad0a56f21438b28bcc0f1a17fcb9) 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.
