Stealthium demo detects weight tampering in GPU memory
What happened
On October 19, Hacker News reported a Stealthium method for detecting tampering with model weights in GPU memory, covering ROME attacks that directly rewrite model weights. Stealthium uses a runtime sensor that traces every CUDA kernel launch back to the Python code that issued it, which is how it detects weight rewrites happening in GPU memory. The disclosed progress centers on this detection mechanism: linking CUDA kernel launches to their Python code to identify direct weight tampering by ROME attacks.
