Metaphor-based Jailbreak Attacks on Text-to-Image Models

Chenyu Zhang, Lanjun Wang, Wenhui Li, Yi Tu et autres

Text-to-image (T2I) models commonly incorporate defense mechanisms to prevent the generation of sensitive images. Unfortunately, recent jailbreak attacks have shown that adversarial prompts can effectively bypass these mechanisms and induce T2I models to produce sensitive content, revealing critical safety vulnerabilities. However, existing …

Culture-based Adversarial Attack on Text-to-Image Models

Fei Yang, Chenyu Zhang, Lanjun Wang

Text-to-image (T2I) models aim to output high-quality images based on the input prompt. It commonly incorporates safety filters to prevent the generation of sensitive images. In this study, we aim to reveal the safety vulnerabilities of black-box T2I models in a real-world …

Reason2Attack: Jailbreaking Text-to-Image Models via LLM Reasoning

Chenyu Zhang, Lanjun Wang, Yunyun Ma, Wenhui Li et autres

Text-to-Image(T2I) models typically deploy safety filters to prevent the generation of sensitive images. Unfortunately, recent jailbreaking attack methods manually design instructions for the LLM to generate adversarial prompts, which effectively bypass safety filters while producing sensitive images, exposing safety vulnerabilities of T2I …
