Towards Understanding Jailbreak Attacks in LLMs: A Representation Space Analysis

EMNLP 2024main

Large language models (LLMs) are susceptible to a type of attack known as jailbreaking, which misleads LLMs to output harmful contents. Although there are diverse jailbreak attack strategies, there is no unified understanding on why some methods succeed and others fail. This paper explores the behav…
