What is Cyber Threat Hunting?

Essentially, cyber threat hunting refers to the proactive search for cyber threats or vulnerabilities that could leave your IT infrastructure vulnerable to attack. Cyber threat hunting seeks out any threats that may have made it past your system’s baseline cybersecurity. The cyber threat hunter will then find any concealed threats even if they are unknown, unresolved, or undetected.

Traditionally, threat-hunting solutions relied solely on the skills and time of security analysts and other cybersecurity professionals. However, those skills are now in high demand due to a lack of qualified technicians with the required experience, education, and instincts. This fact has made cyber threat hunting difficult and time-consuming. The expected human error involved also makes threat-hunting solutions less effective.

These days, hackers are just as sophisticated as the professionals trying to stop them. This forces companies to evaluate threat actor intentions and capabilities while monitoring for vulnerabilities – without any threat-hunting security tools or skills. However, a few open-sourced and commercially available threat-hunting tools can serve as effective threat-hunting solutions.

Why do Organizations Need Cyber Threat Hunting?

Cyber-attacks are growing more sophisticated and cybercriminals don’t rest. While most of your automated cybersecurity can securely deal with threats, they are not entirely foolproof. This is because cyber-attacks continue to evolve - becoming smarter and harder to detect. Given enough time and resources, these modern threats can break past most automated defense solutions.

Modern malware and viruses can also lay dormant within a network and go undetected for days when using typical cybersecurity protocols. Joseph Ochieng’s study revealed that cybercriminals can spend almost 192 days in a system on average before being discovered. This leaves your entire system open to ongoing damage from the inside. A cyber threat-hunting tool can act as a stealthy hunter catching these files unawares.

In 2022 IBM’s “Cost of a Data Breach Report”, the average cost of a data breach was estimated at US$ 4.35 million. Companies can no longer afford to be simply reactive in their approach to cyber threats. Effective cyber threat hunting helps organizations understand the areas of their cybersecurity that need extra attention. This will ultimately reduce the potential damage that can be done - which is a lot.

Objectives of Cyber Threat Hunting

The best way to determine which cyber threat hunting platform is suited to your business needs is to evaluate the potential attacker’s goals, capabilities, and opportunities.


The type of data you collect and store, the size of your enterprise, and the amount of money that flows through your business daily are indicators of your level of risk and the types of threats your system is vulnerable to. Determine if a cyber-attack will target your customers, or finances, or try to hold operations for a ransom. This will help you to measure the methods of attack you will likely experience. Formative threat-hunting solutions will prioritize this detection.


Staying updated on the latest cybersecurity trends will help your threat-hunting platform understand what attacks might be launched against your network. For example, if you know that your most valuable company asset is customer PII, you should research the latest and most successful cyber-attacks aimed at the theft of customer information. This will give you a head start in identifying security gaps in your network.


Closing the door to known and unknown threats before they can be used against you is an important way of proactively protecting your network. Being a victim of the same cyber-attacks as other companies gives your customers the view that your company lacks awareness and is not prepared. This passive commitment to network security is bad for your brand in general. However, maintaining effective cyber threat hunting will reduce the likelihood of that.

Threat Hunting Process: How Threat Hunting Works

There are specific threat-hunting steps that can be taken to find an actual threat. These steps can be sorted into the following six simple steps as follows:

Step One: Form a Hypothesis

This is where threat hunters will establish what type of threat they’re looking for. The hypothesis will be informed by analysis of previous malware attacks, trends in cybersecurity attacks, and critical areas of attack. Threat hunters must make use of threat-intelligent techniques to locate and develop a plan of action. This step is where your cyber threat-hunting goal is set.

Step Two: Data Collection

Threat hunting cannot be done without a sufficient amount of data collection. In step 2, your cyber hunter needs to establish centralized and organized data. Cyber threat hunting should also be built on the data of previous threat-hunting exploits. This ensures that threat hunting is continuous and that only the relevant data is used to critically analyze threats. Threat hunters can then use the data collected to determine if the hypothesis is worth expanding on.

Step Three: Critical Analysis

This step of the process is crucial and will provide the data needed to mitigate potential threats. Patterns and processes must be carefully monitored for anomalies and suspicious behaviors. As more analysis takes place, your threat-hunting team also learns new tactics and develops its threat-hunting capabilities.

Step Four: Critical Response

Time is of the essence when threat hunting and a rapid response is necessary to ensure your network’s safety. The response needs to consider both long-term and short-term measures to prevent and mitigate the threat. This includes disabling users, implementing security patches, blocking IP addresses, updating authorization privileges, altering network configurations, or introducing new identification requirements. The main goal of threat hunting is to protect the host, prevent system damage, and eliminate the possibility of a future attack.

Step Five: Isolation and Elimination

This step sees the threat dealt with in isolation to prevent further damage to the network. Using advanced threat detection sandboxing techniques will make sure that suspicious malware is quarantined away from other files. This will reduce the risk of damage to the server and automatically mitigate the threat.

Step Six: Evaluation

The last step of the process involves understanding the threat-hunting techniques and practices vital to your business. The evaluation also means implementing stricter controls over areas in your network that are vulnerable to cyber-attacks. This allows your IT team to predict and proactively safeguard your network before any damage can be done. The best threat-hunting tool is preventative measures.

6 Steps of cyber Threat Hunting

Once these steps are involved, your threat-hunting team will be ready to fight off malware, but there are more threat-hunting tools and techniques that you can use.

Cyber Threat Hunting Methodologies

Threat hunting methodologies encompass various approaches and techniques used to proactively search for and detect cyber threats within a network. It's important to note that these methodologies often work in tandem, and threat hunters may employ a combination of approaches depending on the specific needs and goals of an organization. Here are some common threat hunting methodologies as described in the provided resources:

Hypothesis-driven investigation

This methodology involves formulating hypotheses about potential threats based on known attack patterns, threat intelligence, or suspicious indicators. Threat hunters then investigate the network to validate or refute these hypotheses. By leveraging crowdsourced attack data and insights into attackers' tactics, threat hunters can identify and respond to emerging threats.

Investigation based on known Indicators of Compromise (IOCs) or Indicators of Attack (IOAs):

Threat hunters leverage threat intelligence to catalog and analyze known IOCs and IOAs associated with new threats. These indicators serve as triggers to uncover hidden attacks or ongoing malicious activities. By proactively searching for these indicators, threat hunters can detect and mitigate threats before they cause significant damage.

Advanced analytics and machine learning investigations:

This methodology combines data analysis and machine learning algorithms to sift through large volumes of information and identify anomalies that may indicate potential malicious activity. Skilled analysts investigate these anomalies to uncover stealthy threats. By using advanced analytics and machine learning, threat hunters can detect sophisticated attack techniques that may evade traditional security defenses.

Threat Hunting Maturity Model

The threat hunting maturity model is a framework that helps organizations assess their level of readiness and effectiveness in conducting threat hunting activities. It consists of five levels, with each level representing a different stage of maturity in threat hunting capabilities. The levels range from ad-hoc and reactive to proactive and automated.

  • Level 0: At the ad-hoc level, organizations have no formal threat hunting program in place and only respond to threats as they arise.
  • Level 1: There is a basic reactive threat hunting program in place, but it is not consistent or proactive.
  • Level 2: The proactive level involves a more structured and strategic approach to threat hunting, with dedicated resources and processes in place.
  • Level 3: Advanced level threat hunting incorporates automation and machine learning to enhance the effectiveness and efficiency of threat hunting activities.
  • Level 4: When threat hunting procedures have been optimized, it is integrated into the overall security strategy and continuously evolves to stay ahead.

Tools and Techniques Used for Cyber Threat Hunting

Cybersecurity experts use critical thinking, manual forensic investigation, and automated threat-hunting tools to protect companies. Threat hunters seek out insider threats and outsider attack surfaces to hunt down potential attackers or vulnerabilities before they can become a problem. This is done by executing a well-rehearsed incident response (IR) plan.

A few critical elements of any cyber threat-hunting mission are:

  • Data analytics and reporting
  • OS and network knowledge
  • Information security experience

Evolved Cyber Threat Hunting Techniques

Cyber threat hunting today has evolved from more traditional and manual methods. Thanks to advancements in technology, we can threat hunt more effectively and efficiently. Coupled with advances in automation, machine learning, and behavior analytics, cyber threat hunting is imperative to an organization’s cybersecurity strategy. Here are some core techniques used today:

  • Baselining: As its name suggests, this technique helps threat hunters understand what a normal baseline IT operation looks like within an organization. This acts as a baseline for comparison when threats are possible. Baselining is critical as it helps establish a clear difference between malicious and non-malicious events to identify anomalies.
  • Attack-Specific Hunts: Unlike baselining - where the overall environment is analyzed - this technique focuses on a threat actor or threat alone. This helps threat hunters find malicious activity faster. Attack-specific hunts can often be limiting, however, which is why they are often used in conjunction with baselining to get better results.
  • Time Sensitivity: Threat hunting is generally constrained by time. Time is valuable when protecting against malicious attacks. Threat hunters should validate their baseline terms and data periodically to keep up with the rapid pace of hackers.
  • Help from Third-Party Sources: Threat hunting can be an overwhelming process because of the sheer number of threats and data that need to be analyzed. Getting some help ensures your organization is better protected. These third-party sources can also help with geolocation, encrypted traffic metadata, ruling out false positive leads, and more.

Types of Cyber Threat Hunting

Threat-hunting techniques differ in organizations, industries, and environments. However, many of the core threat-hunting strategies remain mostly the same. The main three types of cyber threat hunting include:

Structured threat hunting

This type of threat hunting is more organized. It is based on an indicator of attack and tactics, techniques, and procedures of an attacker. This method allows you to gain a better understanding of the techniques used by attackers. Structured threat hunting is usually based on previous methods of attacks found which means that it’s driven by a particular technique.

Unstructured threat hunting

An unstructured threat hunt is primarily based on indicators of compromise. These hunts are initiated based on a trigger. The trigger then pushes threat-hunting programs to look for pre- and post-detection behavior.

Situational threat hunting

A situational threat hunt comes from an internal risk assessment of the vulnerabilities of a specific organization - unique to its IT environment. This type of cyber threat hunt involves uniquely generated data from previous attack assessments to check if a similar situation might repeat itself.

Different types of Threat Hunting

Challenges of Cyber Threat Hunting

As cyber threat hunting is a proactive activity - that not many are familiar with - it may come with challenges. Here are some of the common challenges of cyber threat hunting:

  1. Lack of Skilled Hunters. While threat-hunting solutions have evolved, there is still a human element to the methods. Hiring skilled cyber threat hunters who can use the tools, techniques, and software better can be difficult with the current gap in cybersecurity talent in the industry.
  2. Gathering Wrong or Poor Data. To identify hidden cyber threats and keep watch over a network, it’s essential to have the right security data in the first place. Having poor data will waste time and resources - leading to inefficient results.
  3. Using Outdated Threat Intelligence. Threat hunters need to be equipped with the latest and most accurate cyber-attack tactics, techniques, and procedures. It is vital to generate an effective threat-hunting hypothesis model and threat intelligence. This allows threat hunters to better analyze attack trends and protect the organization.

Frequently Asked Questions

Threat intelligence is a data set about attempted or successful intrusions, usually collected and analyzed by automated security systems with machine learning and AI. Threat hunting, on the other hand, is a proactive approach to identifying previously unknown or ongoing threats within an organization's network. It uses threat intelligence as a starting point, but goes beyond it by conducting a thorough, system-wide search for bad actors. While threat intelligence focuses on data and analysis, threat hunting involves skilled IT security professionals manually searching, monitoring, and neutralizing threats before they can cause significant damage. Additionally, threat hunting can uncover threats that have not yet been identified by automated systems, making it a crucial component of a comprehensive cybersecurity strategy.

Reacting to cyber threats alone is insufficient because it introduces a time gap between the occurrence and detection of threats, allowing attackers to cause damage. Reactive measures often rely on known attack patterns and may miss new or sophisticated threats. Advanced Persistent Threats (APTs) and insider threats, which are designed to evade detection, require proactive monitoring and analysis.

By implementing proactive threat hunting, you enable early detection and mitigation of threats, reducing dwell time and potential impact. Proactive threat hunting also provides organizations with better visibility into their security posture, enhances incident response capabilities, and fosters continuous improvement. By combining proactive threat hunting with reactive measures, organizations can stay ahead of evolving threats and better protect their systems and data.
