    Will the Agent Recuse Itself? Measuring LLM-Agent Compliance with In-Band Access-Deny Signals

    Thamilvendhan Munirathinam

    cs.CR · cs.AI

    As autonomous LLM agents increasingly hold real credentials and operate infrastructure without a human in the loop, operators have no standard way to tell an agent that a resource is off-limits. Access controls either let the agent in (it has valid credentials) or hard-fail it (indistinguishable from any other client). We propose a third mode: a lightweight, published in-band deny signal -- the Recuse Signal -- that a server emits over a...

    AttackPathGNN: Cross-function vulnerability detection in smart contracts using state interference graphs and conjunction pooling

    Gabriela Dobrita, Simona-Vasilica Oprea, Adela Bara

    cs.CR · cs.AI

    Existing learning-based detectors for Solidity smart-contracts reduce vulnerability detection to syntactic pattern matching within single functions, yet many of the most consequential exploits (The DAO, Cream Finance) exist not in any individual function but in the relationship between functions and in the combination of conditions that made the attack feasible. Thus, we propose AttackPathGNN, a graph neural network (GNN) that reframes...
