GPU-Resident Rootkits: Why Wiping the OS Won’t Save Your AI Cluster
GPU-Resident Rootkits: Why Wiping the OS Won’t Save Your AI Cluster TL;DR Standard security protocols focus on the CPU and Storage, but GPU-Resident Rootkits hide in VRAM and firmware, bypassing OS-level detection. These threats leverage Direct Memory Access (DMA) to survive disk wipes and propagate across high-speed interconnects like NVLink, requiring a shift toward hardware-level attestation and strict IOMMU enforcement.
