AMD, Nvidia, and Intel GPUs could be capable of hosting malicious code

Hackers may have figured out a way to store and execute malicious code on a graphics card, potentially allowing it to avoid detection by antivirus software. The code has also reportedly been sold via a hacking forum, and so far we’ve no further indication of how dangerous the technique could be.

Code that sits undetected in GPU memory is likely very dangerous due to the potential difficulty associated with removing it, which could rely on flashing the GPU entirely—an already risky affair. However, the overall threat of the reported method will depend on what it takes to implant the code into GPU memory to begin with.
