Adversarial suffix attacks can bypass safety alignment in LLMs.

Greedy Coordinate Gradient attack…Greedy Coordinate Gradient attack achieves near-100% attack success rate on aligned models, but structured prompt boundaries reduce exploitability by 64%.

Context & Methodology

Adversarial suffixes are optimised token sequences that override safety training — structured prompt architectures provide defence-in-depth against these attacks.
