What is Cyber Threat Hunting? How to Stay Ahead of Attacks

Contents

Cyberattacks are becoming more frequent and sophisticated as threat actors continually sharpen their tactics and upgrade their tools. Defending against these evolving threats is increasingly complex, especially in a landscape where cybersecurity ROI is measured in loss prevention rather than revenue generation.

Cyber threat hunting offers a proactive way to secure your environment by actively seeking out threats that evade traditional defenses. However, manual threat hunting is time-consuming, resource-intensive, and complicated by a growing shortage of skilled professionals.

In this blog, we’ll unpack everything you need to know about cyber threat hunting and show how Hyperautomation can help your team stay ahead of attackers by streamlining detection, investigation, and response without requiring massive overhead.

What is Threat Hunting in Cybersecurity?

The value of cyber threat hunting lies in these key properties:

  • Proactive approach: Unlike traditional security measures that react to alerts, threat hunting is a proactive process. Threat hunters actively seek out potential threats rather than waiting for them to be detected or, worse, erupt into a critical incident. 
  • Augmenting automated systems: Threat hunting complements automated security tools by identifying threats that may have slipped past those systems.
  • Human expertise: It relies on the knowledge and skills of threat hunters who use their expertise, tools, and methodologies to identify malicious activities. 
  • Targeted searches: Threat hunters develop hypotheses about potential threats based on threat intelligence, known attack techniques, and other factors, then they search for evidence to validate those hypotheses.
  • Focus on advanced threats: Threat hunting is beneficial for identifying advanced persistent threats (APTs) and other sophisticated attacks that can evade traditional security measures.

Why is Cyber Threat Hunting Important?

Most SOC tools operate reactively — they wait for indicators of compromise (IOCs) or known attack signatures to trigger alerts. However, today’s adversaries are stealthy, often residing in networks undetected for weeks or months. Cyber threat hunting flips the script.

Threat hunting proactively searches for unknown, suspicious behavior and zero-day threats that traditional detection tools miss. The benefits include: 

  • Early threat detection and response: Threat hunters spot anomalies before damage occurs, enabling rapid, contained responses to reduce breach impact. Early detection and response can significantly reduce the potential damage and costs associated with cyberattacks.
  • Identification of persistent and complex threats: Advanced persistent threats (APTs) often evade SIEMs or endpoint detection and response (EDR). Threat hunting reveals long-dwelling attackers using subtle tactics.
  • Improved incident response efficiency: Hunting improves context and decision-making for incident response (IR) teams, reducing mean time to investigate (MTTI) and resolve (MTTR). By identifying and mitigating threats proactively, threat hunting strengthens an organization’s overall security posture. 
  • Enhanced threat intelligence: The insights gained from threat hunting can also improve an organization’s threat intelligence and help them better understand their adversaries. 

How Cyber Threat Hunting Works: 6 Methods

Cyber threat hunting isn’t a single technique — it’s a flexible, proactive approach that combines human expertise with data, context, and tooling. Depending on your team’s goals, tools, and maturity level, different methodologies can be used to uncover hidden threats and eliminate adversaries before they cause damage. Here are six of the most effective threat hunting methods in use today.

1. Hypothesis-Driven Hunting

This method begins with a well-formed theory about how an adversary might be operating within your environment. Hunters often base these hypotheses on current threat intelligence, past incidents, or a known threat actor’s tactics. 

For example, a threat hunting team may ask, “Is an attacker using PowerShell for lateral movement across endpoints?” They then query logs, examine user activity, and look for anomalies that might validate or disprove that theory. This structured, scientific approach allows analysts to pursue purposeful leads and systematically uncover sophisticated threats.

2. Indicator of Attack (IoA)-Based Hunting

Rather than reacting to alerts, IoA-based threat hunting proactively searches for signs of attacker behavior that signal malicious intent — even if no breach has occurred. Analysts look for behavioral patterns and tactics often used by adversaries, such as a sudden surge in failed login attempts, suspicious registry modifications, or abnormal user behavior during off-hours. 

By focusing on indicators of attack (IoAs) instead of indicators of compromise (IoCs), teams can identify active intrusion attempts earlier in the kill chain, often before data exfiltration or lateral movement occurs.

3. Advanced Analytics and Machine Learning

Threat hunting at scale benefits significantly from security automation, particularly through advanced analytics and machine learning (ML). These AI models are trained on historical attack data and behavioral baselines, helping analysts identify statistical anomalies and outliers across massive datasets. 

For example, suppose a user suddenly begins downloading gigabytes of data from an unfamiliar endpoint. ML-driven tools can flag the deviation from normal behavior in that case, even if no specific IoA has been defined. This method increases speed and coverage, especially in cloud or hybrid environments.

4. Structured Hunting

Structured threat hunting leverages formal models and frameworks like MITRE ATT&CK to organize and guide investigations. By using well-defined tactics, techniques, and procedures (TTPs), analysts can systematically scan for known threat behaviors across endpoints, identities, and networks.

This method is beneficial for standardizing team processes, ensuring knowledge sharing, and aligning with compliance or threat modeling requirements. It also enables better documentation and repeatability of hunts, making it a valuable tool for maturing a cybersecurity program.

5. Unstructured Hunting

Unstructured hunting relies more on analyst intuition and real-world experience than on formal rules or frameworks. In this method, seasoned hunters follow their instincts, identifying suspicious patterns, log entries, or correlations that don’t match any known indicators — but still “feel off.” 

This open-ended approach can surface novel attacks, zero-day behaviors, or insider threats that evade automated detection. While more time-consuming, unstructured hunting is crucial in developing hypotheses for future structured hunts and refining detection rules.

6. Situational or Entity-Driven Hunting

This method prioritizes hunting based on specific contexts — such as critical assets, high-risk users, or sensitive business functions. For example, threat hunters may target systems housing personally identifiable information (PII) or monitor executive accounts likely to be targeted in phishing or business email compromise (BEC) attacks. 

Situational or entity-driven hunting ensures security teams protect what matters most by focusing on high-value targets and contextual threat intelligence. It can also quickly act on suspicious activity that might otherwise get lost in the noise.

Cyber Threat Hunting Process

Effective threat hunting follows a straightforward process. Here’s how top-performing teams approach it.

  • Trigger: A hunt often starts with a clue — a suspicious login, a new TTP from a threat intel feed, or a hunch. Triggers inform what to investigate.
  • Investigation: Hunters use SIEM, EDR, network traffic, and log data to dig deeper. Enrichment, correlation, and historical context help determine risk.
  • Resolution: If a threat is confirmed, it’s escalated for response, and hunting insights are used to improve detection rules and workflows in the future.
