Eight Threat Hunts You Can Run Today

Guide

Expose hidden threats using the log data you already collect and turn common telemetry into repeatable threat hunting workflows.

This guide outlines eight practical threat hunts you can run using the log data in your SIEM to identify early and late indicators of compromise.

Threats often slip past preventive controls, leaving security operations teams with limited time and competing investigation priorities. Proactive threat hunting helps teams surface suspicious activity earlier by using telemetry already present in the environment.

This guide provides eight structured hunts with clear hypotheses, what to look for, and the log sources that support each approach. The hunts cover common attacker behaviors, including suspicious processes, scripting abuse, persistence, lateral movement, and DNS‑based activity.

Key Questions This Guide Helps You Answer

• What log sources should you collect to support consistent threat hunting in your SIEM?
• How can you detect suspicious processes that mimic legitimate system files?
• Which behavioral changes signal living-off-the-land activity and malicious parent-child process chains?
• What indicators help identify scripting abuse, including encoded PowerShell execution and remote script downloads?
• How can you hunt for persistence using registry changes, scheduled tasks, services, and WMI subscriptions?
• What patterns suggest lateral movement and abnormal internal authentication behavior?
• Which DNS behaviors may indicate command-and-control or data exfiltration?

How Exabeam Helps Operationalize These Threat Hunts

Exabeam helps security operations teams turn these threat hunts into repeatable workflows by collecting and organizing telemetry, correlating related signals, and adding behavioral context. New-Scale Fusion, New-Scale SIEM, and LogRhythm SIEM support baselining, dynamic risk scoring, and timeline-based investigation so analysts can identify abnormal activity, prioritize what warrants review, and validate findings faster using the data they already collect.
