'BlueHammer' Exploit Targets Windows, Potentially Impacting 1 Billion+ Devices

""At that point, [the attackers] basically own the system, and can do things like spawn a SYSTEM-privileged shell.""
A security researcher known as Chaotic Eclipse published exploit code for a Windows vulnerability named BlueHammer, which is a zero-day flaw without a Microsoft patch. This local privilege escalation vulnerability allows attackers with low-level access to gain SYSTEM-level control. Will Dormann confirmed the exploit's functionality, describing it as a combination of a TOCTOU bug and a path confusion issue. Once attackers achieve SYSTEM-level access, they can access the Security Account Manager database, leading to full machine takeover.
