Unified Attack Framework Bypasses Statistical Generative LLM Watermarks
KGW, SynthID, DipMark
Researchers identified a shared weakness across popular large language model watermarking methods and introduced a unified attack framework. The approach exploits the link between detection scores and token probability shifts to undermine watermarking detection.
