Large Language Models (LLMs) are vulnerable to naturalistic adversarial attacks crafted using Markov Decision Processes (MDPs) and Monte Carlo Tree Search (MCTS). These attacks generate natural-language prompts that elicit harmful, violent, or discriminatory responses from the LLMs, even those with built-in safety mechanisms. The attacks are transferable across different LLMs, demonstrating a generalized vulnerability.

Large Language Models (LLMs) are vulnerable to a novel black-box jailbreaking attack, ECLIPSE, which leverages the LLM's own capabilities as an optimizer to generate adversarial suffixes. ECLIPSE iteratively refines these suffixes based on a harmfulness score, bypassing the need for pre-defined affirmative phrases used in previous optimization-based attacks. This allows for effective jailbreaking even with limited interaction and without white-box access to the LLM's internal parameters.

Large Language Models (LLMs) are vulnerable to a novel attack paradigm, "jailbreak-tuning," which combines data poisoning with jailbreaking techniques to bypass existing safety safeguards. This allows malicious actors to fine-tune LLMs to reliably generate harmful outputs, even when trained on mostly benign data. The vulnerability is amplified in larger LLMs, which are more susceptible to learning harmful behaviors from even minimal exposure to poisoned data.

The ALERT-Motion framework demonstrates a vulnerability in text-to-motion (T2M) models where an attacker can craft subtly modified text prompts (adversarial prompts) that cause the model to generate motions significantly different from those intended by the benign prompt, yet semantically similar to a target motion specified by the attacker. The attack leverages a large language model (LLM) to autonomously generate these adversarial prompts, bypassing simple keyword-based detection mechanisms…

A vulnerability allows bypassing safety filters in text-to-image (T2I) models using a multi-agent framework ("Atlas") powered by Large Language Models (LLMs). Atlas iteratively generates and refines prompts, leveraging a Vision-Language Model (VLM) to assess filter activation and an LLM to select effective prompts that maintain semantic similarity to the original, malicious prompt while evading the filter. This enables the generation of images containing unsafe content.

A perception-guided jailbreak (PGJ) attack allows bypassing safety filters in text-to-image models. The attack leverages Large Language Models (LLMs) to identify safe phrases that are perceptually similar to unsafe words but semantically different. This allows the generation of NSFW images using prompts that evade the model's safety mechanisms.

A heuristic token search attack, termed HTS-Attack, can bypass safety mechanisms in text-to-image (T2I) models, allowing generation of NSFW content. The attack iteratively replaces tokens in a malicious prompt with semantically similar tokens from the model's vocabulary, avoiding detection by prompt and image checkers. The method leverages a surrogate CLIP model to maintain semantic similarity to the target NSFW prompt.

Large Language Models (LLMs) are vulnerable to jailbreaking attacks leveraging synthetically generated prompts. A novel pipeline, SAGE-RT, generates a diverse dataset of 51,000 prompt-response pairs designed to exploit LLMs' vulnerabilities across various categories of harmfulness. These prompts successfully jailbreak state-of-the-art LLMs in a significant percentage of tested sub-categories, including 100% of macro-categories for certain models like GPT-4 and GPT-3.5-turbo. The vulnerability…

Large Language Models (LLMs) are vulnerable to an "Analyzing-based Jailbreak" (ABJ) attack that exploits their analytical and reasoning capabilities. ABJ crafts prompts that instruct the LLM to analyze seemingly innocuous data (e.g., character traits, features, job descriptions) related to a malicious intent, leading the LLM to generate harmful content despite its safety training. This bypasses standard safety mechanisms designed to prevent direct requests for harmful information.

A vulnerability in GPT-4V's facial recognition safety mechanisms allows for automated jailbreaking attacks using Large Language Models (LLMs) to bypass safety features and elicit unintended facial identification responses. The attack, termed "AutoJailbreak," optimizes prompts through iterative refinement with an LLM "red-teaming" model, significantly increasing the attack success rate. This vulnerability exploits weaknesses in GPT-4V's prompt processing and safety alignment, allowing malicious…
