Malware that runs inside GPUs (graphics processing units) can be harder to detect, but is not completely invisible to security products. Researchers from Intel division McAfee Labs analyzed a proof-of-concept GPU malware program dubbed JellyFish that was released in March. JellyFish’s creators claimed that one of the advantages of GPU malware is that it can snoop on the host computer’s memory through a feature called DMA (direct memory access) While this is true, exposing critical portions of the system’s memory to the GPU requires kernel privileges.”]
