Part 5/7:
The Steel Fox malware leverages a known vulnerability in a third-party driver, called "WinRing0.sys," to escalate its privileges and achieve system-level access. By bringing this vulnerable driver with them and exploiting its flaws, the malware operators can bypass modern Windows security measures and maintain a persistent presence on the infected system.
From there, the malware connects back to its command-and-control server using SSL and TLS 1.3 encryption, exfiltrating the stolen data while remaining stealthy and difficult to detect.
