The package is a RAT performing full exfiltration and executing remote commands through a custom RPC protocol over WebSockets, and eventually establishing a reverse shell.


Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers.

  • exfiltration-credentials

  • rat

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