🧑‍🔧️ An Empirically-grounded tool for Automatic Prompt Linting and Repair: A Case Study on Bias, Vulnerability, and Optimization in Developer Prompts (http://arxiv.org/pdf/2501.12521v1.pdf)

• The implementation of PromptDoctor demonstrated a significant reduction in bias-prone prompts by 68.29% and strengthened vulnerability against injection attacks by 41.81%.
• Automated tools for prompt linting and optimization, particularly PromptDoctor, improved under-performing developer prompts by 37.1%, suggesting enhanced performance reliability.
• A detailed analysis revealed that 10.75% of developer prompts are susceptible to injection attacks, highlighting a crucial area for security enhancements in software engineering.

🎶 Tune In, Act Up: Exploring the Impact of Audio Modality-Specific Edits on Large Audio Language Models in Jailbreak (http://arxiv.org/pdf/2501.13772v1.pdf)

• Audio edits, such as noise injection and accent conversion, significantly increase Attack Success Rates by 25% to 45% in Large Audio Language Models, highlighting potential vulnerabilities.
• SALMONN-7B displays high sensitivity to audio editing types, compared to models like SpeechGPT and Qwen2-Audio, which show more robustness with ASR changes under 3%.
• Comprehensive evaluations demonstrate that audio-specific edits like tone adjustment and speed change are critical for future development of security measures in language models.

🦺 Can Safety Fine-Tuning Be More Principled? Lessons Learned from Cybersecurity (http://arxiv.org/pdf/2501.11183v1.pdf)

• Adversarial attacks on large language models (LLMs) present a persistent challenge, with attackers often able to bypass security defenses through methods such as jailbreaks and prompt injections, which are analogous to zero-day exploits in cybersecurity.
• LLMs need the integration of principled safety approaches into their design to mitigate risks, similar to strategies employed in cybersecurity, which include formal verification and memory-safe programming.
• Fine-tuning for safety in LLMs is likened to retrofitting security into existing models, which remains challenging due to the complexity and dynamic nature of potential attacks.

🏢 Jailbreaking Large Language Models in Infinitely Many Ways (http://arxiv.org/pdf/2501.10800v1.pdf)

• Large Language Models (LLMs) like Claude-3.5, GPT-4, and others can be bypassed using 'Infinitely Many Meanings' (IMMs) attacks which encode prompts in ways that evade existing safety mechanisms.
• Research indicates an inverse correlation between the size of LLMs and their robustness against certain encoded or paraphrased prompts, suggesting larger models are not inherently safer.
• Developing effective defensive strategies for LLMs requires addressing the challenge of encoding attacks which currently have a high success rate in bypassing safety guardrails.

🤖 VulnBot: Autonomous Penetration Testing for A Multi-Agent Collaborative Framework (http://arxiv.org/pdf/2501.13411v1.pdf)

• VulnBot demonstrates superior performance in automated penetration testing compared to existing models with a subtask completion rate of 69.05%.
• The multi-agent system effectively mitigates context loss and enhances task execution through role specialization and inter-agent communication.
• Employing Retrieval Augmented Generation and Memory Retriever modules significantly improves the accuracy and contextual understanding in real-world scenarios.
