ExplorIt, a simulation-based ADS fuzzer enhanced with systematic formalization of interaction behaviors, formalizes the runtime EGO-to-NPC interactions through drivable area estimation and can then deterministically mutate scenarios to curate more critical interactions by making EGO and NPC head for shared drivable are...

This work proposes ActivationBackdoor, an inference-time backdoor attack that composes two activation-level components for trigger detection and backdoor behavior injection, and shows that ActivationBackdoor attains attack success comparable to training-time backdoor baselines while preserving high clean-task accuracy...

Collaborative inference enables cost-effective deployment of large language models by partitioning layers across multiple participants and forwarding intermediate activations between participants in a pipeline, but these transmitted activations also create a new attack surface: a malicious participant can manipulate in...
