About this tag
The system32 exploit tag covers a specific Windows 0day vulnerability where Windows Defender is abused to write an attacker-controlled binary into the System32 folder. This local privilege escalation technique, detailed in CloudSEK's RedSun research, exploits a race condition in Defender's remediation workflow. A standard user can trigger Defender to restore a malicious file into System32, which then executes with SYSTEM privileges. The attack does not require a kernel exploit, UAC bypass, or administrator rights, making it a significant trust failure in how Defender handles file restoration after detection. Discussions on this tag focus on the technical mechanics of the race-to-write-and-execute attack and its implications for Windows security.
