How Hackers Exploit Vulnerable Drivers
Source: YouTube · John Hammond · published Oct 5, 2023 · 23:59
The video demonstrates how attackers use "Bring Your Own Vulnerable Driver" (BYOVD) attacks to gain complete control of computers by exploiting signed but vulnerable kernel drivers 0:00-0:03.
Key Takeaways:
• Kernel drivers provide "keys to the kingdom" access, making them prime targets for hackers who exploit signed but vulnerable drivers 0:48-0:51
• Modern malware like Spy Boys, Terminator EDR killer, and BlackCat ransomware use BYOVD techniques to bypass security controls 1:22-1:31
• The video demonstrates KD mapper, a tool that loads unsigned drivers by exploiting a vulnerable Intel driver from 2015 3:35-3:50
• The attack chain involves creating a kernel loader driver that executes shell code, injects into Windows Defender, and establishes command and control 11:36-12:07
• The proof of concept successfully gains system-level access by bypassing Microsoft's signature enforcement through BYOVD 21:04-21:25
The video illustrates how BYOVD attacks remain a dangerous threat vector that can completely compromise system security.

inside your computer behind the desktop and underneath the operating system is the kernel and the kernel runs code called drivers that facilitate communication between the hardware and software like the operating system your computer runs what that means is these drivers offer extreme full control and complete access to the computer now that means that hackers threat actors and adversaries love trying to gain access and manipulate kernel drivers so one technique in modern malware campaigns is to bring your own vulnerable driver or byobd that's where the hacker the threat actor and the adversary will purposefully place a vulnerable driver in the environment so that they can compromise it they can hack into it and then they will have full control over the machine it is an attractive Target f…
