Blurry Images Create a ‘Comfort Zone’ for Jailbreaking Multimodal LLMs

A new study from Westlake University shows that when harmful text is rendered as low‑resolution, blurry, or noisy images, multimodal large language models become significantly easier to jailbreak despite still recognizing the text, revealing a U‑shaped risk curve and a simple mitigation that decouples OCR from safety checks.

When Blurry Images Create an Attack Comfort Zone for Multimodal LLMs

Westlake University's AGI Lab shows that when harmful text is rendered as low‑resolution, blurry or noisy images, multimodal large language models can still read the content but their safety filters fail, creating an 'attack comfort zone' that dramatically raises jailbreak success rates across several models.
