GraphRectify: Graph-Based Transfer of Adversarial Example Detectors Across Neural Networks

Adversarial example detectors are often tied to the classifier backbone they were trained on, limiting reuse when the protected model is replaced or upgraded. Directly transferring such detectors across backbones is challenging because different networks generally produce incompatible internal representations. We propo...

ChronosAttack: Adversarial Tool Scheduling Attacks on LLM Agents

This work introduces ChronosAttack, a delay-only scheduling attack that changes when authentic tool responses arrive without modifying, adding, removing, or accelerating them, to show that tool-response timing can itself form an attack surface in asynchronous LLM agents.
