    A team of developers has created a rootkit for Linux systems that uses the processing power and memory of graphics cards instead of CPUs in order to remain hidden. The rootkit, called Jellyfish, is a proof of concept designed to demonstrate that completely running malware on GPUs (graphics processing units) is a viable option. This is possible because dedicated graphics cards have their own processors and RAM.
