Bypassing the Safety Training of Open-Source LLMs with Priming Attacks

With the recent surge in popularity of LLMs has come an ever-increasing need for LLM safety training. In this paper, we show that SOTA open-source LLMs are vulnerable to simple, optimization-free attacks we refer to as $\textit{priming attacks}$, which are easy to execute and effectively bypass alignment from safety training. Our proposed attack improves the Attack Success Rate on Harmful Behaviors, as measured by Llama Guard, by up to $3.3\times$ compared to baselines.
