A Story of Llamas and Hammers: GPUHammer Exposes a Hardware Attack Surface for AI Systems - Ludwig

BSides San Antonio 2026 June 13 at St. Mary's University GPUHammer shows that modern GPUs are not just rapid computing engines, but memory systems with a real attack surface. This talk explains how a Rowhammer-style attack can induce bit flips in GDDR6, why GPU architecture changes the defender’s problem, the consequences for large-scale AI and cloud systems, and what current hardware, firmware, and software mitigations still leave open.
