GPUs Could Become Trojan Horses for Future Cyber Attacks

Trojan Horse for Malware

The graphics card inside your computer is a powerful tool for gaming and creative work, but it can also potentially serve as a Trojan horse for malware. Cybercriminals are finding ways to exploit graphics cards and their VRAM to inject malicious code into your system. The approach is claimed to have worked during a proof-of-concept hack on both discrete and integrated GPUs from AMD, Intel, and Nvidia.

Because antivirus software today cannot scan the graphics card’s own video RAM, known as VRAM, hackers are now targeting GPUs to carry out their dirty work. On the other hand, conventional methods used today that target the system’s main memory would trigger the antivirus software.

According to Bleeping Computer, a brief description of the hack was posted on a hacker forum, where one seller was trying to sell his proof-of-concept method to exploit the VRAM on GPUs. The seller stated that the method worked on Intel’s integrated UHD 620 and 630 graphics, as well as discrete solutions including the AMD Radeon RX 5700 and Nvidia GeForce GTX 1650. It’s unclear if the attack would also work on other GPUs, like the recent Radeom RX 6000 series from AMD and theGeforce RTX 3000 series from Nvidia, both of which have seen high demand and short supply.
