threat-hunting

Threat Hunting equips you to conduct hypothesis-driven threat investigations across Windows endpoints, network traffic, and cloud identity using Sigma-based detection rules, MITRE ATT&CK mapping, and offline triage tools. Execute C2 hunting via JA4 fingerprinting and beaconing analysis, detect post-exploitation techniques like LSASS dumping and LOLBin abuse, and validate detection coverage with purple-team emulation.

Threat Hunting helps you hunt threats and engineer detections across endpoints, networks, and cloud using ATT&CK, Sigma rules, and telemetry.

Frequently asked questions

AI-generated answers based on this skill's SKILL.md and metadata

What is threat-hunting and what does it cover?

Threat-hunting is a skill for conducting hypothesis-driven threat investigations across Windows endpoints, network traffic, and cloud identity. It equips you with Sigma-based detection rules, MITRE ATT&CK mapping, and offline triage tools to hunt threats, engineer detections, and validate coverage gaps using purple-team emulation.

How does threat-hunting help detect Windows post-exploitation?

Threat-hunting provides detection strategies for Windows post-exploitation techniques including LSASS dumping, ETW/AMSI tampering, LOLBin abuse, and process injection. You'll learn to use Sysmon telemetry, EVTX triage tools like Hayabusa and Chainsaw, and process tree anomaly detection to identify these attacks.

What sigma rules and windows endpoint detection methods does threat-hunting teach?

Threat-hunting teaches you to build and deploy Sigma rules for Windows endpoint detection, map them to MITRE ATT&CK techniques, and integrate them into detection-as-code CI pipelines. You'll learn to triage EVTX logs and correlate endpoint telemetry with network signals for comprehensive threat visibility.

How can threat-hunting detect C2 beaconing in encrypted traffic?

Threat-hunting covers C2 hunting via JA4 fingerprinting for malware identification, beaconing detection using tools like RITA, and DNS tunneling analysis. These techniques let you hunt command-and-control activity even in encrypted network traffic without decryption.

Does threat-hunting address cloud identity attack hunting?

Yes. Threat-hunting includes cloud identity attack hunting focused on device-code phishing, PRT token theft, and CloudTrail abuse detection. You'll learn to identify Entra ID compromise patterns and validate detections across hybrid cloud-identity environments.

How does threat-hunting validate detection coverage?

Threat-hunting teaches purple-team validation using atomic red team emulation to measure ATT&CK coverage gaps. You'll map detections to the coverage matrix via ATT&CK Navigator and refine your detection engineering based on real adversary behavior simulation.
