From Noise to Signal: Improving Security Log Anomaly Detection Using LLMs with Endpoint-Specific Logs

Christopher Henshaw, Gour Karmakar

Existing approaches to anomalous behaviour log detection, such as Wazuh rely primarily on predefined detection rules, while statistical anomaly detection approaches such as OpenSearch identify deviations from previously observed behavioural patterns. Recent research has investigated LLMs for log anomaly detection because of …

Number Recognition Through Color Distortion Using Convolutional Neural Networks

Christopher Henshaw, Jacob Dennis, Jonathan Nadzam, Alan J. Michaels

Machine learning applied to image-based number recognition has made significant strides in recent years. Recent use of Large Language Models (LLMs) in natural language search and generation of text have improved performance for general images, yet performance limitations still exist for data …

Use and Abuse of Personal Information, Part I: Design of a Scalable OSINT Collection Engine

Elliott Rheault, Mary Nerayo, Jaden Leonard, Jack Kolenbrander et autres

In most open-source intelligence (OSINT) research efforts, the collection of information is performed in an entirely passive manner as an observer to third-party communication streams. This paper describes ongoing work that seeks to insert itself into that communication loop, fusing openly available …
