A multi-round attack against Large Language Models (LLMs) allows bypassing safety mechanisms by iteratively refining prompts to elicit undesired behavior. The attack leverages the LLM's tendency to adjust its response based on preceding interactions, circumventing single-round prompt filtering defenses.

Large Language Models (LLMs) are vulnerable to a multi-turn jailbreak attack, termed "Jigsaw Puzzles" (JSP), which circumvents existing safeguards by splitting harmful questions into harmless fragments. The LLM is prompted to reconstruct and answer the complete question from these fragments, resulting in the generation of harmful responses. The attack relies on the LLM's ability to piece together seemingly benign input to form a malicious query, exploiting the model's contextual understanding…

Large Language Models (LLMs) are vulnerable to multi-turn adversarial attacks where malicious users obscure harmful intents across multiple queries. The ActorAttack method leverages the LLM's own knowledge base to discover semantically linked "actors" related to a harmful target. By posing seemingly innocuous questions about these actors, the attacker guides the LLM towards revealing harmful information step-by-step, accumulating knowledge until the desired malicious output is obtained, even…

Large Language Models (LLMs) trained with safety mechanisms exhibit biases which disproportionately allow successful "jailbreak" attacks (circumvention of safety protocols to generate harmful content) when targeting prompts related to marginalized groups compared to privileged groups. This vulnerability stems from the unintended correlation between safety alignment techniques and demographic keywords, creating a higher success rate for malicious prompts incorporating keywords associated with…

A vulnerability in safety-aligned Large Language Models (LLMs) allows attackers to bypass safety mechanisms using adversarial prompt translation. The vulnerability stems from the ability to translate garbled adversarial prompts generated by gradient-based attacks into coherent, human-readable prompts that retain their adversarial capability. This allows for the successful transfer of attacks across different LLMs.

Large language models (LLMs) controlling robots are vulnerable to jailbreaking attacks. The ROBOPAIR algorithm demonstrates that malicious prompts can bypass safety mechanisms, causing robots to perform harmful physical actions. This vulnerability exploits the LLM's reliance on textual prompts and its potential lack of sufficient contextual understanding to prevent unsafe commands. The attack is effective across different access levels.

Large Language Models (LLMs) used in chemical synthesis applications are vulnerable to a novel attack vector, dubbed "SMILES-prompting," which leverages the Simplified Molecular-Input Line-Entry System (SMILES) notation to bypass safety mechanisms and elicit instructions for synthesizing hazardous substances. The attack exploits the LLM's inability to effectively filter or interpret SMILES strings representing dangerous chemicals, leading to the disclosure of synthesis procedures.

Large Language Models (LLMs) are vulnerable to a novel iterative self-tuning attack (ADV-LLM) that crafts adversarial suffixes. This attack significantly reduces the computational cost of generating effective jailbreaks compared to prior methods, achieving near 100% success rate against various open-source LLMs and high success rates (e.g., 99% against GPT-3.5, 49% against GPT-4) against closed-source models. The attack leverages iterative self-tuning to improve the LLM's ability to generate…

AdaPPA is a jailbreak attack that exploits the varying levels of alignment protection in LLMs at different output positions. It leverages the model's instruction-following capabilities by pre-filling the output with carefully crafted "safe" content, creating a perceived completion and lowering the model's guard before generating malicious content. The attack's effectiveness relies on the adaptive generation of both safe and harmful pre-fill content, strategically placed to exploit weaknesses…

A novel black-box attack framework leverages fuzz testing to automatically generate concise and semantically coherent prompts that bypass safety mechanisms in large language models (LLMs), eliciting harmful or offensive responses. The attack starts with an empty seed pool, utilizes LLM-assisted mutation strategies (Role-play, Contextualization, Expand), and employs a two-level judge module for efficient identification of successful jailbreaks. The attack's effectiveness is demonstrated across…
