During installation, the code exfiltrates basic information and exfiltrates more information to a localhost service as well as starts a reverse shell there. It seems to be an internal test that was uploaded to a public repository.

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: 2026-08-joule-btp-extension


Reasons (based on the campaign):


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


 - The package contains code to exfiltrate basic data from the system, like IP or username. It has a limited risk.
