Check out the latest updates on high vulnerabilities, data breaches and ransomware attacks.

High Vulnerabilities

High Vulnerabilities
Do high vulnerabilities always make organizations easy targets? Not necessarily! Attackers often prioritize targets based on the value of assets, not just vulnerabilities. Even those with low vulnerabilities can be targeted if they hold valuable data or resources.

Researchers Uncover OS Downgrade Vulnerability Targeting Microsoft Windows Kernel

A new attack technique could be used to bypass Microsoft's Driver Signature Enforcement (DSE) on fully patched Windows systems, leading to operating system (OS) downgrade attacks.

"This bypass allows loading unsigned kernel drivers, enabling attackers to deploy custom rootkits that can neutralize security controls, hide processes and network activity, maintain stealth, and much more," SafeBreach researcher Alon Leviev?said?in a report shared with The Hacker News.

The latest findings build on an?earlier analysis?that uncovered two privilege escalation flaws in the Windows update process (CVE-2024-21302?and?CVE-2024-38202) that could be weaponized to rollback an up-to-date Windows software to an older version containing unpatched security vulnerabilities.
