Rootkit: Jellyfish is a Linux based userland gpu rootkit proof of concept project utilizing the LD_PRELOAD technique from Jynx (CPU), as well as the OpenCL API developed by Khronos group (GPU). Code currently supports AMD and NVIDIA graphics cards. However, the AMDAPPSDK does support Intel as well. ~ https://github.com/x0r1/jellyfish

These tools are PoCs, they will work but the code hasn't been updated for the last 3 years so you'll have to put a lot of work and effort into turning these into actual tools.
