Windows 10 Devices Are at Risk From the BootHole Vulnerability

Researchers have discovered a flaw in Windows and Linux-based operating systems. The flaw, nicknamed “BootHole,” can grant a hacker near-complete control over a victim’s PC. And unfortunately, we’re now waiting on Microsoft to patch the vulnerability.

How the BootHole Exploit Works

The exploit first came to light when researchers at Eclypsium discovered it. BootHole is not a strain of malware. Instead, it’s the name for the hole in the defenses that a virus can exploit.

At the time of writing, this problem only affects Linux boot systems and those that use Secure Boot. Unfortunately, Windows uses Secure Boot, which means it’s weak to this exploit.

Once malware enters the system via the BootHole exploit, it can use arbitrary code to gain control over as much of the computer as it pleases.

The boot process is an important part of a computer because it defines how an operating system loads. If malware gets in between the cracks of the boot process, it can control how the operating system works and cause damage.

Can You Fix the BootHole Exploit?

Unfortunately, because this flaw is related to Windows’ boot sequence, it’s not something that you can fix yourself. Microsoft has to release a patch that fixes the BootHole flaw. However, this isn’t an easy task.

The boot sequence is an essential part of keeping the operating system stable. As such, if Microsoft rushes out a buggy patch for the flaw, it will cause system instability.

As a result of this, it may take Microsoft a while to release a patch that fixes BootHole. And we’re all reliant on Microsoft doing so.

How to Stay Safe From Exploits

While waiting for Microsoft to patch BootHole, you’ll need to be extra careful to avoid malware that would allow hackers to take advantage of the vulnerability.
