The COLD-Attack framework allows for the generation of stealthy and controllable adversarial prompts that can bypass safety mechanisms in various Large Language Models (LLMs). The attack leverages an energy-based constrained decoding method to generate fluent and contextually coherent prompts designed to elicit harmful or unintended responses from the targeted LLM, even under constraints like specific sentiment or phrasing. This allows attacks to evade detection mechanisms solely relying on…

Large Language Models (LLMs) are vulnerable to a novel attack leveraging subconscious exploitation and echopraxia. Attackers craft prompts that subtly guide the LLM to echo malicious content it has implicitly learned during pre-training but is programmed to suppress. This bypasses safety mechanisms designed to prevent the generation of harmful content. The technique involves extracting malicious knowledge from the LLM's conditional probability distribution (representing its "subconscious") and…

A vulnerability exists in several Large Language Models (LLMs) allowing evasion of safety filters through carefully crafted prompts leveraging role-playing scenarios. The vulnerability is exploited by prompting the LLM to adopt a specific persona or scenario (e.g., "You are a helpful assistant in a fantasy world where all actions are permitted") that overrides built-in safety restrictions, resulting in the generation of unsafe or undesirable outputs. The attack is facilitated by structured…

Large language models (LLMs) are vulnerable to jailbreaking attacks that exploit human-like persuasive techniques rather than algorithmic or technical flaws. Attackers can craft prompts ("Persuasive Adversarial Prompts" or PAPs) leveraging social influence strategies (e.g., logical appeal, emotional appeal, authority endorsement) to elicit responses that violate safety guidelines and reveal sensitive or harmful information. The effectiveness of these attacks surpasses traditional…

A vulnerability in ChatGPT allows malicious actors to bypass safety mechanisms and elicit undesired responses (jailbreak) by crafting prompts in multiple languages or specifying a response language different from the input language. This is amplified by prompt injection techniques.

Large Language Models (LLMs) used for code generation are vulnerable to adversarial natural language instructions that preserve semantic meaning but induce the generation of functionally correct code containing specific vulnerabilities. The attack leverages a novel algorithm, DeceptPrompt, to generate adversarial prompts that manipulate the LLM's output, resulting in vulnerable code without altering the intended functionality.

Large Language Models (LLMs) exhibit an inherent response tendency, predisposing them towards affirmation or rejection of instructions. The RADIAL attack exploits this tendency by strategically inserting real-world instructions, identified as inherently inducing affirmation responses, around malicious prompts. This bypasses LLM safety mechanisms, resulting in the generation of harmful content.

A prompt injection vulnerability in OpenAI's custom GPT models allows attackers to extract the system prompt and potentially leak user-uploaded files. Attackers craft malicious prompts that manipulate the LLM into revealing sensitive information, even when defensive prompts are in place. The vulnerability is exacerbated when the model includes a code interpreter.

A vulnerability exists in large language models (LLMs) utilizing in-context learning (ICL). Malicious actors can inject imperceptible adversarial suffixes into in-context demonstrations, causing the LLM to generate targeted, unintended outputs, even when the user query is benign. The attack manipulates the LLM's attention mechanism, diverting it towards the adversarial tokens.

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.
