Vision Language Models (VLMs) integrated into autonomous driving (AD) systems are vulnerable to a black-box adversarial attack method termed Cascading Adversarial Disruption (CAD). The vulnerability stems from the model's susceptibility to optimized visual perturbations that disrupt the decision-making reasoning chain (perception, prediction, and planning). Attackers can generate adversarial images or physical patches by aligning visual noise with deceptive textual semantics in the model's…

Vision Language Models (VLMs) are vulnerable to visual prompt injection attacks via text-to-image obfuscation. While these models often possess safety guardrails for standard text-based inputs, they fail to apply equivalent safety alignment to textual instructions embedded visually within an image. An attacker can overlay malicious instructions (e.g., requests for illegal acts, hate speech) onto an image file and submit it to the model. The model’s Optical Character Recognition (OCR) or visual…

Large Language Model (LLM) tool-calling systems are vulnerable to adversarial tool injection attacks. Attackers can inject malicious tools ("Manipulator Tools") into the tool platform, manipulating the LLM's tool selection and execution process. This allows for privacy theft (extracting user queries), denial-of-service (DoS) attacks against legitimate tools, and unscheduled tool-calling (forcing the use of attacker-specified tools regardless of relevance). The attack exploits vulnerabilities…

Large Audio-Language Models (LALMs) are vulnerable to a stealthy adversarial jailbreak attack, AdvWave, which leverages a dual-phase optimization to overcome gradient shattering caused by audio discretization. The attack crafts adversarial audio by adding perceptually realistic environmental noise, making it difficult to detect. The attack also dynamically adapts the adversarial target based on the LALM's response patterns.

A bimodal adversarial attack, PBI-Attack, can manipulate Large Vision-Language Models (LVLMs) into generating toxic or harmful content by iteratively optimizing both textual and visual inputs in a black-box setting. The attack leverages a surrogate LVLM to inject malicious features from a harmful corpus into a benign image, then iteratively refines both image and text perturbations to maximize the toxicity of the model’s output as measured by a toxicity detection model (Perspective API or…

Large Language Models (LLMs) are vulnerable to a novel agentic-based red-teaming attack, PrivAgent, which uses reinforcement learning to generate adversarial prompts. These prompts can extract sensitive information, including system prompts and portions of training data, from target LLMs even with existing guardrail defenses. The attack leverages a custom reward function based on a normalized sliding-window word edit similarity metric to guide the learning process, enabling it to overcome the…

Large Language Models (LLMs) are vulnerable to transferable ensemble black-box jailbreak attacks. The vulnerability allows an attacker to bypass safety mechanisms and elicit undesired or harmful responses from the LLM by using an ensemble of LLM-as-attacker methods that optimize malicious prompts, adaptively adjusting resources based on prompt difficulty, and strategically modifying prompt semantics to evade detection.

Large Vision-Language Models (VLMs) are vulnerable to a novel black-box jailbreak attack, IDEATOR, which leverages a separate VLM to generate malicious image-text pairs. The attacker VLM iteratively refines its prompts based on the target VLM's responses, bypassing safety mechanisms by generating contextually relevant and visually subtle malicious prompts.

Large Language Model (LLM) agents are vulnerable to obfuscated adversarial prompts that exploit tool misuse. These prompts, crafted through prompt optimization techniques, force the agent to execute tools (e.g., URL fetching, markdown rendering) in a way that leaks sensitive user data (e.g., PII) without the user's knowledge. The prompts are designed to be visually indistinguishable from benign prompts.

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.
