Cross-Modal Safety Alignment: Is textual unlearning all you need?

Trishna Chakraborty, Erfan Shayegani, Zikui Cai +5

Recent studies reveal that integrating new modalities into Large Language Models (LLMs), such as Vision-Language Models (VLMs), creates a new attack surface that bypasses existing…

Ensemble-based Blackbox Attacks on Dense Prediction

Zikui Cai, Yaoteng Tan, M. Salman Asif

We propose an approach for adversarial attacks on dense prediction models (such as object detectors and segmentation). It is well known that the attacks generated by a single surro…

Blackbox Attacks via Surrogate Ensemble Search

Zikui Cai, Chengyu Song, Srikanth Krishnamurthy +2

Blackbox adversarial attacks can be categorized into transfer- and query-based attacks. Transfer methods do not require any feedback from the victim model, but provide lower succes…
