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: 2025-03-marinff

 - obfuscation


 - The package contains code to create a reverse shell, allowing an attacker to execute any commands on the victim's machine.
