Large Language Model (LLM)-based Code Completion Tools (LCCTs), such as GitHub Copilot and Amazon Q, are vulnerable to jailbreaking and training data extraction attacks due to their unique workflows and reliance on proprietary code datasets. Jailbreaking attacks exploit the LLM's ability to generate harmful content by embedding malicious prompts within various code components (filenames, comments, variable names, function calls). Training data extraction attacks leverage the LLM's tendency to…

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 black-box query-response optimization attack (QROA). QROA iteratively refines a malicious prompt suffix using a surrogate model to maximize a reward function that measures the likelihood of eliciting harmful content from the LLM. This attack does not require access to the model's internal parameters or logits; it operates solely via standard query-response interactions.

GPT-4o exhibits vulnerability to jailbreak attacks via audio prompts, despite enhanced safety against text-based attacks. Successful jailbreaks can be achieved by converting text prompts, including those optimized for adversarial attacks against other LLMs (demonstrated using GCG, AutoDAN, PAP, and BAP methods), into audio using text-to-speech (TTS) synthesis. This circumvention allows elicitation of unsafe responses from GPT-4o that would otherwise be prevented by its safety mechanisms. The…

Large Language Models (LLMs) are vulnerable to prompt injection attacks that can bypass their internal copyright compliance mechanisms, causing them to generate verbatim copyrighted text. The vulnerability stems from insufficient robustness against prompt engineering techniques that manipulate the model into ignoring or circumventing its safety filters designed for copyright protection.

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 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 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.

Large Language Model (LLM)-integrated web applications using Langchain (and potentially similar middleware) are vulnerable to Prompt-to-SQL (P2SQL) injection attacks. Unsanitized user prompts can be crafted to cause the LLM to generate malicious SQL queries, leading to unauthorized database access (read and write operations). This vulnerability bypasses attempts to restrict the LLM through prompt engineering alone.
