Practical threat hunting relies heavily on the MITRE ATT&CK framework. This globally accessible knowledge base catalogs real-world adversary tactics, techniques, and procedures (TTPs).
This specific query filters all process creation logs to display instances where certutil.exe was ordered to connect to an external URL or force a file download. Step 3: Analyze Anomalies and Investigate
