Academic & Research

• SPILLWAY: Separating Target Admission from Sanitization to Defend Tool-Using Agents against Prompt Injection

Source: arXiv cs.CR, Nov 06. Tool-using agents act on email, files, and payments, so an instruction hidden in a web page or a shared document can make an agent send data or money to an attacker. Many runtime defenses put a language model on the decision that lets an action through, so the decision depends on

• Signed but Not Safe: Requirement Integrity in Multi-Agent LLM Handoffs

Source: arXiv cs.CR, Nov 06. Enterprise AI agents increasingly split a user's request across subagents and merge their results, and each handoff can summarize away, alter or ignore a requirement. We report a preregistered study with synthetic, exactly scorable tasks comparing free-text, structured JSON and s

• MEvince: Knowledge-Constrained LLM Reasoning for Technique Identification from Malware Reports

Source: arXiv cs.CR, Nov 06. Mapping behavioral intelligence in malware analysis reports to ATT&CK techniques supports threat analysis and defense, but reliable identification remains challenging. Supporting evidence is often scattered across long, heterogeneous reports, while closely related techniques shar

• JailBound: FOL-Guided Jailbreak Evaluation for Exploring LLM Behavioral Boundaries

Source: arXiv cs.CR, Nov 06. As large language models (LLMs) are increasingly deployed as general-purpose conversational assistants, they must handle diverse user requests while reliably refusing harmful ones. Jailbreak attacks craft adversarial instructions or conversational contexts to elicit unsafe respon

• A Gingerbread House for LLM Agents: Source-Planned Honeypots That Lure Autonomous Attackers into an Isolated Shadow

Source: arXiv cs.CR, Nov 06. LLM agents can exploit web vulnerabilities fast enough that patching may come too late. Deception against such agents has mostly lured them away from a real target that stays reachable. We study a different arrangement: an LLM defender plans a static honeypot from the application

• Beyond Instruction Override: Benchmarking Indirect Prompt Injection with Task-Tampering Attacks

Source: arXiv cs.CR, Nov 06. Indirect prompt-injection (IPI) benchmarks predominantly test planted instructions that redirect a tool-using agent toward an attacker-chosen task. Yet attacker-controlled content can instead tamper with the outcome of the task already in progress. A buyer's dispute evidence can

• LABBA: LLM-Assisted Behavioral Biometric Authentication

Source: arXiv cs.CR, Nov 06. Behavioral biometrics have emerged as a promising complement to traditional physiological biometrics by leveraging dynamic human characteristics. These modalities offer advantages including continuous authentication, inherent liveness detection, and greater resistance to credenti

• FedReason: Large Language Models as Weight-Space Meta-Aggregators for Heterogeneous Federated Learning

Source: arXiv cs.CR, Nov 06. Federated learning servers combine client models with a fixed aggregation rule, and each rule in common use is designed for one kind of heterogeneity. We study whether a large language model (LLM) that inspects the client models can choose the rule itself, without any training on
