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.. The Jellyfish rootkit is advanced malware exploiting GPUs to operate stealthily in Linux, performing tasks like keylogging while evading detection methods.

Security researchers have demonstrated how it might be possible to place backdoor rootkit software on a network card. Guillaume Delugr. He used publicly available documentations and open source tools to develop a firmware debugger. He also reverse-engineered the format of the EEPROM where firmware code is stored, as well as the bootstrap process of the device.
