SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Detects and analyzes keylogger activity across endpoints using YARA rules, API hook detection, and registry/hook monitoring to enable rapid triage and incident response.

Core Features & Use Cases

  • YARA-based detection for WH_KEYBOARD_LL hooks and common keylogging patterns.
  • KQL/Sigma-based detection for high-rate keystroke activity and data flow.
  • Use Case: Respond to suspected keylogger on an enterprise endpoint; triage with immediate indicators and recommended remediations.

Quick Start

Prompt Claude to run the YARA-based keylogger detector against the target endpoint and report any matches.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I detect keylogger activity on Windows endpoints for incident response?▼

Detect keylogger activity by applying YARA rules for WH_KEYBOARD_LL hooks, monitoring keyboard input rates with KQL, and scanning for API hooks to triage suspected enterprise incidents.

What forensic artifacts indicate a keylogger infection?▼

Keylogger forensic artifacts include WH_KEYBOARD_LL hook installations, abnormal keyboard input rates, and malicious API hooks, which YARA and Sigma rules identify during endpoint triage.

Can I use YARA rules to find keyloggers in an enterprise environment?▼

Yes, you can apply YARA rules to target common keylogging patterns and low-level keyboard hooks across enterprise Windows endpoints to rapidly identify malicious activity.

How do I triage a suspected keylogger incident using KQL and Sigma detection?▼

Triage keylogger incidents by running KQL and Sigma patterns to detect high-rate keystroke activity and data flow anomalies, then correlating these artifacts to generate incident reports.

What is the best way to monitor keyboard input for malware forensics?▼

The best way to monitor keyboard input for malware forensics is combining YARA-based API hook detection with KQL queries that flag abnormal keystroke data flows across endpoints.

Does this keylogger detection method support remediation and reporting?▼

Yes, the detection method provides structured guidance for response and remediation, correlating endpoint artifacts to generate comprehensive incident reports for keylogger activity.
