Windows login exploit puts Dell laptops at serious risk

Ana sayfa / News

A dangerous Windows login exploit has surfaced, allowing attackers to bypass passwords, gain full control, and embed hidden malware deep in Dell laptops. Fortunately, Dell has already issued fixes.

The flaw involves Dell’s ControlVault, a security chip meant to isolate fingerprints and passwords from the operating system. Researchers discovered five vulnerabilities collectively called “ReVault” that break this isolation.

With physical access, an attacker can:

Even after reinstalling Windows, the malware can survive.

Attention iPhone owners! A new security vulnerability has emerged

Tommy Mysk revealed that applications, including TikTok, Facebook, Twitter, LinkedIn, and Bing, leak data from iPhones through notifications.

The issue centers on the Unified Security Hub (USH), a secondary chip found in many Dell Latitude and Precision laptops. Hackers can execute code directly on it, allowing persistent access.

That’s what makes this exploit especially dangerous. It doesn’t just compromise files it compromises the hardware layer most users can’t reach.

These flaws affect more than 100 models, mostly in the business-class category. However, many of these laptops are sold to everyday users, so the warning applies beyond just enterprise environments.

If someone gets hold of your device, they could bypass the login entirely and install malware without needing your permission or your password.

Dell responded quickly by rolling out firmware and software updates. If you own a Latitude or Precision device, check Dell’s site and install the latest fixes today.

The Windows login exploit reminds us that not all threats come through the internet. Sometimes, the real danger lies inside the hardware we trust most.
