New Windows Driver Signature Bypass Enables Rootkit Installs!

🔍 Security researcher Alon Leviev has exposed a critical flaw in Windows that allows attackers to downgrade kernel components, bypass Driver Signature Enforcement (DSE), and install rootkits on fully patched systems. This attack leverages outdated software components introduced through the Windows Update process, making it possible to deploy unsigned kernel drivers and hide malicious activity. Despite significant kernel security improvements, attackers can exploit this downgrade method to compromise security features and deploy malware.

🛡️ Impact: Rootkits installed through this bypass can disable crucial security mechanisms, leaving systems vulnerable to data breaches and advanced persistent threats.

💡 Why It Matters:

Attackers can downgrade a system’s kernel components to exploit previously patched vulnerabilities.This attack affects fully updated Windows systems, including Windows 11.Organizations must strengthen endpoint security and monitor downgrade attacks closely to prevent unauthorized kernel-level compromises.
