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.


## Affected packages

- `joule-sbx-poc`
