What problem does it solve?

This Skill empowers security analysts to proactively identify and investigate potential threats within their environment by leveraging powerful Sigma detection rules and established threat hunting methodologies.

Core Features & Use Cases

Sigma Rule Application: Utilize a comprehensive set of pre-defined Sigma rules to detect suspicious activities across various log sources (process creation, network connections, file events, registry modifications).
Threat Investigation Workflow: Follow a structured approach for triaging alerts, gathering contextual information, performing timeline analysis, and implementing containment strategies.
Rule Conversion: Convert Sigma rules to formats compatible with popular SIEM platforms like Splunk, Elasticsearch, and Microsoft Sentinel.
Use Case: When a security alert fires indicating potential malware execution, use this Skill to apply relevant Sigma rules, analyze the associated process and network logs, and determine the scope and impact of the incident.

Quick Start

Use the threat-hunting skill to analyze suspicious PowerShell commands using Sigma rules.
