🟥 Red Teaming GPT-4V: Are GPT-4V Safe Against Uni/Multi-Modal Jailbreak Attacks? (http://arxiv.org/pdf/2404.03411v1.pdf)
- GPT-4 and GPT-4V demonstrate superior resilience against jailbreak attacks, notably outperforming open-source models.
- Llama2 and Qwen-VL-Chat are the most robust among the evaluated open-source models, with significant resilience to various jailbreak methods.
- Visual jailbreak methods have limited transferability and effectiveness, especially when compared to textual jailbreak attacks.
✍🏼 Great, Now Write an Article About That: The Crescendo Multi-Turn LLM Jailbreak Attack (http://arxiv.org/pdf/2404.01833v1.pdf)
- Crescendo, a multi-turn jailbreak attack, consistently achieved high attack success rates across various state-of-the-art large language models (LLMs), including GPT-4, GPT-3.5, Gemini-Pro, Claude-3, and LLaMA-2 70b.
- Misinformation-related tasks, such as those involving election controversies or climate change denial, were among the easiest for Crescendo to execute successfully across all evaluated models.
- Automated tool Crescendomation demonstrated the feasibility of automating Crescendo attacks, achieving near-perfect attack success rates for several tasks, indicating its potential for broader application.
🥸 Learn to Disguise: Avoid Refusal Responses in LLM's Defense via a Multi-agent Attacker-Disguiser Game (http://arxiv.org/pdf/2404.02532v1.pdf)
- Employing a multi-agent adversarial game approach significantly enhances the ability of large models to generate responses that safely disguise their defensive intent.
- The proposed multi-agent framework outperforms traditional methods by optimizing game strategies to adaptively strengthen defense capabilities without altering large model parameters.
- The curriculum learning-based process iteratively increases the model's capability to generate secure and disguised responses, achieving higher effectiveness in response disguise compared to existing approaches.
🚪Exploring Backdoor Vulnerabilities of Chat Models (http://arxiv.org/pdf/2404.02406v1.pdf)
- Distributed triggers-based backdoor attacks achieve over 90% attack success rates on chat models without compromising the models' normal performance on clean samples.
- The backdoor remains effective with attack success rates above 60% even after downstream re-alignment, demonstrating the persistence of the backdoor.
- Model size affects the effectiveness of backdoor attacks, with larger models showing more pronounced susceptibility.
♊ Two Heads are Better than One: Nested PoE for Robust Defense Against Multi-Backdoors (http://arxiv.org/pdf/2404.02356v1.pdf)
- Nested Product of Experts (NPoE) significantly outperformed existing defense mechanisms in mitigating backdoor attacks across various trigger types, with up to 94.3% reduction in attack success rate (ASR).
- NPoE demonstrated robustness against complex multi-trigger backdoor attacks, effectively lowering ASR to below 10% in diverse NLP tasks and sometimes outperforming models trained on benign data only.
- The incorporation of multiple shallow models within the NPoE framework to simultaneously learn different backdoor triggers proved critical for enhancing defense capabilities against mixed-trigger settings.
