Large Language Model (LLM)-based agents, due to their multi-agent architecture and role-based interactions, are vulnerable to adversarial attacks that exploit the system's design and agent roles. Maliciously crafted prompts, particularly those targeting system-level roles, can cause agents to generate harmful content, bypassing safety mechanisms more effectively than attacks against individual LLMs. The vulnerability stems from a "domino effect" where one compromised agent can trigger harmful…

Large Language Models (LLMs) are vulnerable to jailbreaking attacks exploiting cognitive overload induced by multilingual prompts, veiled expressions, and effect-to-cause reasoning. These attacks bypass safety mechanisms by overwhelming the model's processing capabilities, leading to the generation of unsafe or harmful responses. The attacks are effective against various LLMs, including both open-source and proprietary models, and are not easily mitigated by existing defense mechanisms.

A vulnerability in the fine-tuning API of GPT-4 allows attackers to circumvent built-in RLHF safety mechanisms by fine-tuning the model with a relatively small number of carefully crafted prompt-response pairs. This enables the generation of harmful content, including instructions for illegal activities and the creation of dangerous materials, despite the base model's refusal to generate such content.

A system prompt leakage vulnerability in GPT-4V allows extraction of internal system prompts through carefully crafted, incomplete conversations combined with image input. Extracted prompts can be used as highly effective jailbreak prompts, bypassing safety restrictions and leading to undesirable outputs, including revealing personally identifiable information from images.

Multimodal Large Language Models (MLLMs) are vulnerable to a novel attack vector where query-relevant images, generated using techniques like Stable Diffusion and typography, bypass safety mechanisms and elicit unsafe responses even when the underlying LLM is safety-aligned. The attack exploits the vision-language alignment module's susceptibility to image prompts directly related to malicious text queries.

Large Language Models (LLMs) are vulnerable to a targeted linguistic fuzzing attack that exploits the complexity of human language to bypass safety guardrails. The attack, termed "Jade," leverages transformational-generative grammar rules to systematically increase the syntactic complexity of benign seed questions, making them increasingly difficult for LLMs to recognize as malicious. This leads to the generation of unsafe content, even when the underlying semantics remain unchanged.

Updated 12/29/2024

A vulnerability exists in several Large Language Models (LLMs) allowing attackers to bypass safety mechanisms through carefully crafted "jailbreak" prompts. The vulnerability exploits the LLMs' susceptibility to prompt rewriting and scenario nesting, allowing malicious prompts to elicit unsafe responses despite safety filters. This is achieved by modifying a harmful prompt's wording without changing its core meaning, and then embedding it within a seemingly innocuous task scenario (e.g., code…

Large Language Models (LLMs) are vulnerable to a novel "DeepInception" attack that leverages the models' personification capabilities to bypass safety guardrails. The attack uses nested prompts to create a multi-layered fictional scenario, effectively hypnotizing the LLM into generating harmful content by exploiting its tendency towards obedience within the constructed narrative. This allows for continuous jailbreaks in subsequent interactions.

Large Language Models (LLMs) are vulnerable to persona modulation attacks, a black-box jailbreak technique that leverages an LLM assistant to generate prompts causing the target LLM to adopt harmful personas and produce unsafe outputs. This vulnerability circumvents built-in safety mechanisms, enabling the generation of responses related to illegal activities (e.g., synthesizing drugs, building bombs, money laundering), hate speech, and other harmful content. The attack's effectiveness is…

Large Vision-Language Models (VLMs) are vulnerable to jailbreaking attacks via typographically rendered visual prompts. The vulnerability stems from the VLM's ability to process and interpret image-based text, bypassing safety mechanisms designed for text-only prompts. Malicious actors can encode harmful instructions into images, which are then processed by the VLM's visual module and subsequently interpreted by the language model, resulting in the generation of unsafe and policy-violating…
