Actively Exploited

Overview

Researchers from ReliaQuest have discovered that attackers are using a combination of open-source tools, specifically ClickFix and PySoxy, to maintain persistent access to compromised systems after an initial social engineering attack. This method allows them to bypass traditional security measures and maintain control over their targets. The findings highlight how attackers are increasingly leveraging readily available tools to extend their foothold within networks, making it harder for organizations to detect and respond to breaches. Companies need to be aware of these tactics and strengthen their defenses against social engineering and the use of such tools. It's essential for organizations to continuously monitor their systems and educate employees about potential phishing attacks.
