DecoyTrace: Toxic Decoys for Active Defense in Decentralized Federated Learning

DecoyTrace is presented, a proactive cyber deception-based defense for strictly serverless DFL environments that deploys a mobile DecoyNode that generates decoy challenges using chaotic maps, disseminates a dual model based on neighbor trust, and evaluates them using three-state semantic metrics.

Render Before Reading: Visual Rendering as a Prompt Injection Defense

This paper studies the role played by the adversarial data's input modality, and identifies a systematic asymmetry: multimodal LLMs are more likely to follow adversarial instruction when they appear as text than when the same instruction is delivered through a non-textual channel.

PrivacySkills: How Privacy Guidance Shapes Source Selection in LLM Agents

PrivacySkills is introduced, a controlled framework for evaluating how agents choose among acquisition pathways that provide the same task-relevant value: consulting publicly available personal information, accessing confidential sources, or interacting with the user.

Similarity Is Not Validity: Defending LLM Semantic Caches Against Poisoning

This work proposes a novel defense that recovers necessary information needed to distinguish valid from invalid cache hits from the raw text of the cache key, and proves that Deletion Gain stays positive when a deletion leaves text close enough to the rewrite, and searches for such deletions with a sliding window.

SINGED: Correct Outputs Do Not Certify Safe Execution in LLM Agents

This work introduces SINGED (Source Integrity and the Nonidentifiability Gap in Execution Decisions for LLM Agents), a controlled benchmark covering five primary and two held-out task families and exposes a rank-, evidence-, and choice-sensitive outcome-to-execution gap.

When Tools Silently Lie: Evaluating and Mitigating Blind Compliance in Tool-Augmented Data Agents

Tool-augmented data agents rely on tool outputs for analytical decisions. Yet successful execution can return plausible but incorrect evidence, requiring agents to decide whether to trust or verify it. Understanding this failure requires examining both the evidence obtained through checking and the answer ultimately ad...

An Empirical Study and Assessment of EU AI Act Compliance Checkers

It is found that the quality of AIACCs varies significantly and that they currently can only serve as early-stage orientation tools, and design principles for the implementation of more reliable compliance-support tools are offered.

Black October? The Week AI Changed the Cybersecurity Conversation

Critical flaws, compromised release channels and agentic AI threats landed within days of each other in mid-October 2026. Why “Black October” may say more about how well we now find weaknesses than about the attacks themselves. The post Black October? The Week AI Changed the Cybersecurity Conversation appeared first on GPT-Lab.
