arXiv:2606.05609v1 Announce Type: cross Abstract: As large language models (LLMs) are widely deployed, identifying their vulnerability through jailbreak attacks becomes increasingly critical. Optimization-based attacks like Greedy Coordinate Gradient (GCG) have focused on inserting adversarial tokens to the end of prompts. However, GCG restricts adversarial tokens to a fixed insertion point (typically the prompt suffix), leaving the effect of inserting tokens at other positions unexplored. In this paper, we empirically investigate \emph{slots}, i.e., candidate positions within a prompt where t
The increasing deployment of Large Language Models across sensitive applications makes understanding and mitigating their vulnerabilities, including jailbreak attacks, critical for security and reliability.
This research reveals a novel vector for adversarial attacks on LLMs by exploiting positional vulnerabilities, which can lead to manipulated outputs and undermine trust in AI systems.
Traditional jailbreak defenses focusing on suffix-based adversarial tokens may become insufficient, requiring more sophisticated and context-aware security measures for LLMs.

Exploiting positional vulnerability 'slots' allows more effective and targeted jailbreak attacks on LLMs.
Increased pressure on LLM developers to design models and security mechanisms resilient to these advanced adversarial techniques.
A potential arms race between LLM security and sophisticated attackers, leading to more complex and perhaps less transparent AI systems.
