BARS: Benign-Anchored Ranking and Selection for False Alarm Reduction in Network Intrusion Detection

Benign-Anchored Ranking and Selection (BARS), a two-stage filter that replaces CMD's global anchor with the benign-class mean and applies an order-preserving decorrelation step, is proposed, which reduces false alarms by up to 32% while maintaining similar detection rates, with larger gains under stronger imbalance.

Dithered Gaussian Mechanism for Randomness-Efficient Differential Privacy

The dithered Gaussian mechanism is presented, an alternative to the discrete Gaussian mechanism for differential privacy that discretizes the private output rather than the noise distribution itself, and it is shown that cryptographically secure noise generation with reduced exposure to floating-point vulnerabilities c...

Retrieval Observability Bounds on Provenance Detection for Agent Memory Poisoning: Measured Coverage and a Falsified Standalone Detector

This work formalises this as a framework-agnostic retrieval-to-action provenance graph, classify published attack families by their position relative to it, measure the resulting coverage property against collected agent traces, and falsify the detector's standalone deployment, reversing its own earlier recommendation...

Gravity Falls: A Comparative Analysis of Domain-Generation Algorithm (DGA) Detection Methods for Mobile Device Spearphishing

Both traditional heuristics and some common ML detection methods are ill-suited for consistently evolving DGA tactics observed in Gravity Falls, motivating more context-aware approaches and providing a reproducible benchmark for future evaluation.

Digital Agriculture Sandbox for Collaborative Research

The Digital Agriculture Sandbox is presented, a secure online platform that enables farmers (with limited technical resources) and researchers to collaborate on analyzing farm data without exposing private information and helps bridge the gap between maintaining farm data privacy and utilizing that data to address crit...

nCMD: Benign-Anchored Feature Selection for Imbalanced Network Intrusion Detection

Feature selection is critical for network intrusion detection systems (NIDS) operating under high-dimensional, highly imbalanced traffic, as found in operational and defense networks. Traditional filter methods rank features using global statistics computed symmetrically across classes and thus fail to capture the asym...

Leveraging Soft Prompts for Privacy Attacks in Federated Prompt Tuning

This work proposes PromptMIA, a membership inference attack tailored to federated prompt-tuning, in which a malicious server introduces adversarially crafted prompts and exploits their updates during collaborative training to determine whether a target data point belongs to a client's private dataset.

Federated Computation of ROC and PR Curves

A novel framework for approximating ROC and PR curves using quantiles of the score distribution, which can be computed efficiently under secure aggregation and distributed differential privacy, and provides theoretical guarantees on the approximation quality by bounding the Area Error between the true and estimated cur...

Red-Teaming Text-to-Image Models via In-Context Experience Replay and Semantic-Preserving Prompt Rewriting

ICER is a black-box framework that addresses the gap in text-to-image models in harmful content generation through two components: an LLM-based rewriter that produces fluent, natural-language adversarial prompts, and in-context experience replay that accumulates successful jailbreaking patterns into a reusable prior.

Physics-Attested Federated Learning: Securing Collaborative Anomaly Detection in Critical Water Infrastructure

This work repurposes cyber-physical process invariants from runtime detection heuristics into a verifiable admission requirement for federated updates, mined automatically from clean operational data, and shows invariant compliance using zero-knowledge proofs to allow clients to prove batch adherence without revealing...

How to Tame a Multi-Headed Hydra? Adaptive Multi-Category Safety Steering for Large Language Models

As large language models (LLMs) become increasingly widespread, preventing unsafe responses to harmful prompts is essential for their safe deployment. Activation steering offers an approach to improving LLM safety by modifying internal activations during inference without updating model parameters. However, a single pr...
