TRACE: Trajectory Reasoning through Adaptive Cross-Step Evidence Aggregation for LLM Agents

Vijitha Mittapalli, Shreyaa Jayant Dani, Satya Srujana Pilli +7

Autonomous LLM agents can pursue hidden malicious objectives through sequences of individually benign actions, making sabotage difficult to detect using standard trajectory-level m…

ReasonBreak: Probing Vulnerabilities in Reasoning-Enabled Vision-Language-Action Models for Autonomous Driving

Mohammadreza Teymoorianfard, Jean-Philippe Monteuuis, Jonathan Petit +1

Vision-Language-Action (VLA) models with integrated reasoning have been proposed for end-to-end autonomous driving, assuming a tight coupling between reasoning and trajectory gener…

Network-Level Prompt and Trait Leakage in Local Research Agents

Hyejun Jeong, Mohammadreza Teymoorianfard, Abhinav Kumar +2

We show that Web and Research Agents (WRAs) -- language-model-based systems that investigate complex topics on the Internet -- are vulnerable to inference attacks by passive networ…

VIDSTAMP: A Temporally-Aware Watermark for Ownership and Integrity in Video Diffusion Models

Mohammadreza Teymoorianfard, Siddarth Sitaraman, Shiqing Ma +1

Video diffusion models can generate realistic and temporally consistent videos. This raises concerns about provenance, ownership, and integrity. Watermarking can help address these…

MeanSparse: Post-Training Robustness Enhancement Through Mean-Centered Feature Sparsification

Sajjad Amini, Mohammadreza Teymoorianfard, Shiqing Ma +1

We present a simple yet effective method to improve the robustness of both Convolutional and attention-based Neural Networks against adversarial examples by post-processing an adve…
