Source: kam193 (80f5bbcb50f9c9699a083711bb4d59905b49a198ddcd8c95425030d01d6a45e5)

Installing the package installs a backdoor (a qsocket.io) and automatically uploads access credentials (from the output of the qsocket client) to the remote server.

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

Campaign: 2025-05-free-internet-dns

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.
