Membership Inference in Fine-tuned Diffusion Language Models via Token-level Memorization Asymmetry

This work identifies a phenomenon termed token-level memorization asymmetry through theoretical analysis of diffusion training dynamics and proposes Q-Skew, a quantile-weighted skewness-based indicator for membership inference on finetuned DLMs.

TRIS: A Tri-Layer Retrieval Integrity Sieve Against Knowledge Poisoning

The Tri-Layer Sieve is presented, a middleware defense that sanitizes retrieved evidence through cross-embedding-space clustering with an independent judge model, structural filtering of trigger-payload artifacts, and LLM consistency verification, and exploits a key weakness of retrieval-stage poisoning.

On the existence of consistent adversarial attacks in high-dimensional linear classification

A new error metric is introduced that precisely captures model vulnerability to consistent adversarial attacks -- perturbations that preserve the ground-truth labels, offering theoretical insight into the mechanisms underlying model sensitivity to adversarial attacks.

GENIE: Watermarking Graph Neural Networks for Link Prediction

The rapid adoption, usefulness, and resource-intensive training of Graph Neural Network (GNN) models have made them an invaluable intellectual property in graph-based machine learning. However, their wide-spread adoption also makes them susceptible to stealing, necessitating robust Ownership Demonstration (OD) techniqu...

NeuroPriv: Adversarial Representation Learning for Privacy in Wearable EEG Systems

It is shown that commonly used EEG features can reveal participant identity and demographic attributes in addition to supporting the intended cognitive task, motivating purpose-limited representations and explicit privacy auditing in wearable neurohealth systems.

AgentProv: Auditing Agentic LLM API Providers via Tool-use Policy Probes

Agentic Provenance (AgentProv), the first action-based identity audit for agentic LLM APIs, is introduced: AgentProv fingerprints a deployed model through its categorical tool-call distribution and decides identity via an MMD permutation test.

Position: Privacy Is a Claim, Not a Property of Synthetic Data

It is argued for treating privacy as an explicit, evidence-based scientific claim and recommend that ML venues adopt norms requiring privacy-relevant assertions to be clearly scoped, testable, and contestable.

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.
