Proof-of-Concept Linux Rootkit Leverages GPUs For Stealth

itwbennett writes: 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 is a viable option. Such threats could be more sinister than traditional malware programs, according to the Jellyfish developers, in part because there are no tools to analyze GPU malware, they said.

My understanding of GPU coding environment

Well, let me be the first to tell you that you have none.

This is newsworthy? All it does is hide the original syscall pointers in the GPU. The hook code still needs to be visible to the CPU. pointless/10. 1995 called and their rootkits back.
