👮‍♂ MMJ-Bench: A Comprehensive Study on Jailbreak Attacks and Defenses for Vision Language Models (http://arxiv.org/pdf/2408.08464v1.pdf)

• MMJ-Bench provides a unified framework for evaluating the effectiveness of jailbreak attacks and defenses on vision-language models (VLMs), revealing vulnerabilities through multimodal inputs.
• Experimental results showed that no VLMs were completely robust against jailbreak attacks, with certain optimization-based and generation-based strategies achieving high success rates.
• The effectiveness of defense mechanisms varied, with some significantly reducing attack success rates (ASR) while minimally impacting model utility for normal tasks, indicating a trade-off between security and performance.

⚠️ While GitHub Copilot Excels at Coding, Does It Ensure Responsible Output? (http://arxiv.org/pdf/2408.11006v1.pdf)

• LCCTs like GitHub Copilot and Amazon Q demonstrated a 99.4% and 46.3% success rate, respectively, in jailbreaking attacks, exposing sensitive data such as email and physical addresses.
• Advanced attack methodologies, including 'Contextual Information Aggregation' and 'Hierarchical Code Exploitation', effectively bypass LLM security measures designed for code completion tools.
• Despite the sophistication of LLMs and security protocols, the research reveals significant vulnerabilities in both proprietary and general-purpose models, highlighting the urgent need for enhanced privacy protections and security frameworks.

🔐 An Exploratory Study on Fine-Tuning Large Language Models for Secure Code Generation (http://arxiv.org/pdf/2408.09078v1.pdf)

• Fine-tuning Large Language Models (LLMs) with vulnerability-fixing commits enhances secure code generation, reducing the vulnerability ratio in generated C/C++ code by 6.4% and 5.4%, respectively.
• Parameter-Efficient Fine-Tuning (PEFT) techniques like LoRA and IA3 improve LLMs' ability to generate secure code, with experimentally fine-tuned models reaching a secure code generation ratio of up to 79.2% in C.
• The granularity of the fine-tuning dataset influences LLMs' performance in secure code generation, with function-level fine-tuning achieving better performance in reducing code vulnerabilities than file-level, block-level, or line-level fine-tuning.

🤖 CIPHER: Cybersecurity Intelligent Penetration-testing Helper for Ethical Researcher (http://arxiv.org/pdf/2408.11650v1.pdf)

🦮 Perception-guided Jailbreak against Text-to-Image Models (http://arxiv.org/pdf/2408.10848v1.pdf)

• Perception-guided jailbreak methods exploit vulnerabilities in text-to-image models, enabling the generation of NSFW images by substituting unsafe words with perceptually similar but semantically inconsistent safe phrases.
• Experiments across six open-source and commercial text-to-image models demonstrated the method's efficiency and effectiveness, bypassing safety checkers without requiring complex, resource-intensive queries.
• The method benefits from leveraging large language models (LLMs) to identify suitable substitution phrases that satisfy the Principle of Similarity in Text Semantic Inconsistency (PSTSI), significantly reducing manual effort and improving attack success rates.
