Introducing EvidenceForge: Synthetic security logs that don’t look (as) fake

Description

EvidenceForge is an open-source tool developed by Cisco Talos that generates high-quality, realistic, and causally consistent synthetic security log datasets across multiple formats. It addresses the common limitations of existing synthetic log generators by producing correlated events with shared context, realistic background noise, and causal ordering, enabling effective training, detection validation, and ML model development. The tool uses AI-assisted scenario authoring combined with deterministic generation to create coherent attack narratives and corresponding multi-format logs. It is designed to help security teams overcome the scarcity of realistic labeled datasets without requiring real infrastructure or manual attack simulations. EvidenceForge is not a vulnerability or threat but a tool to improve security operations and training.

Technical Analysis

EvidenceForge is a synthetic log generation tool that creates realistic, multi-format security datasets by using a single canonical event model with shared context objects, ensuring causal and temporal consistency across logs such as Windows Security Events, Sysmon, Linux syslog, Zeek, Snort, and others. Unlike traditional synthetic generators that emit independent events per format, EvidenceForge produces correlated logs that tell a coherent story, including realistic background noise and red herrings. It supports sensor placement modeling to reflect realistic network visibility and uses AI-assisted scenario authoring to collaboratively develop attack narratives. The tool outputs labeled datasets with ground truth documentation and analyst briefings, facilitating SOC training, detection validation, and ML model training. EvidenceForge is open-source and available on GitHub.

Potential Impact

EvidenceForge itself is not a security vulnerability or threat. Instead, it provides security teams with realistic synthetic datasets that improve training, detection tuning, and analytic model validation. This reduces reliance on anonymized, stale, or incomplete public datasets and costly manual simulations. There is no indication of exploitation or risk introduced by EvidenceForge; rather, it enhances defensive capabilities by enabling more effective preparation and testing.

Mitigation Recommendations

No remediation or mitigation is required as EvidenceForge is not a vulnerability or threat. It is a beneficial tool designed to aid security teams in generating realistic training and testing data. Organizations can adopt EvidenceForge to improve their security operations and detection capabilities.
