About this tag
Discussions on WindowsForum.com about digital signature abuse focus on how attackers exploit legitimate signed drivers to bypass Windows security. A prominent example involves ransomware like Akira using a signed Intel CPU tuning driver (rwdrv.sys) to gain kernel-level access and disable Microsoft Defender on Windows 11. This technique highlights the risk of abusing trusted digital signatures to load malicious drivers, undermining driver signature enforcement and other security controls. The tag covers real-world attack vectors, driver vulnerabilities, and the challenges of maintaining trust in signed code within Windows environments.
