What Is Threat Hunting?
Before you can do anything related to threat hunting, you need to ensure you have adequate logging capability to carry out the hunt. When you are done, you need to assess steps to improve your security posture, establishing threat prevention playbooks to address the results moving forward. Ultimately, the most successful hunts are those that are planned. To carry out a threat hunting campaign, a mix of core skills is needed in a team. This is where threat hunting comes in. You can’t possibly uncover everything, even with the best security tools.
If no supporting evidence is found, the hypothesis may be refined or documented as a negative result, which still contributes to organizational understanding and detection maturity. If malicious activity is confirmed, analysts assess the scope of the threat, identify affected assets, and evaluate attacker persistence and movement. Threat hunting data may include endpoint telemetry, authentication logs, network traffic, DNS activity, or cloud audit trails.

These anomalies become hunting leads that are investigated by skilled analysts to identify stealthy threats. After sneaking in, an attacker can stealthily remain in a network for months as they quietly collect data, look for confidential material, or obtain login credentials that will allow them to move laterally across the environment. According to the 2022 Mandiant M-Trends Report, cyberattackers operate undetected for an average of 21 days (a 79% reduction, compared to 2016), but this varies greatly by region.
What is the primary goal of threat hunting?
Intel-based hunting is based on IoCs from threat intelligence sources. Threat hunters identify cyberthreats that might pose a risk to these entities and search for signs of ongoing compromises. A situational hunt is a response to an organization’s unique situation. Formal frameworks, such as the MITRE Adversary Tactics Techniques and Common Knowledge (ATT&CK) framework, guide structured hunts. The hypothesis serves as a springboard for a more in-depth investigation into potential threats. Hunters begin with a hypothesis based on their observations, security data or some other trigger.
The analyst then investigates these potential risks, tracking suspicious behavior in the network. In this case, the analyst uses software that leverages machine learning and user and entity behavior analytics (UEBA) to inform the analyst of potential risks. According to cybersecurity and AI company SonicWall, the number of ransomware attacks grew by 105% globally. Managed threat-hunting services offer expert-level threat detection and response, addressing the skills shortage in cybersecurity. Furthermore, FortiResponder provides managed threat hunting for organizations https://medicarecure.com/2024/01 without a SOC team, ensuring faster detection and response.
Presuming attackers are already in the system and beginning to investigate can help uncover odd behavior that might indicate possible malicious intent.

This integration transforms threat hunting from an isolated activity into a force multiplier that enhances every aspect of your security operations. The primary goal of threat hunting is to proactively discover and neutralize advanced threats that have evaded your existing security controls before they can cause damage. Organizations typically deploy multiple complementary tools to support different aspects of the threat hunting process. Security teams typically employ multiple methodologies depending on their specific objectives, available data, and the nature of the threats they’re investigating.
Whether you’re a builder, defender, business leader or simply want to stay secure in a connected world, you’ll find timely updates and timeless principles in a lively, accessible format. They are usually security analysts from within a company’s IT department who know the organization’s operations well, but sometimes they’re outside analysts. The longer the time between initial access and containment, the more it can cost an organization.
It is often triggered by the discovery of an indicator of compromise (IoC) in an organization’s system. Threat hunting programs are grounded in data—specifically, the datasets gathered by an organization’s threat detection systems and other enterprise security solutions. As a result, organizations can discover intrusions and deploy mitigations much more quickly, reducing the damage attackers can do.
- Retrospective analysis allows teams to apply new detection logic to historical data, uncovering missed activity or extended dwell time.
- Now that we have explored what is threat hunting in cyber security, let’s understand its key methods and techniques.
- If malicious activity is confirmed, analysts assess the scope of the threat, identify affected assets, and evaluate attacker persistence and movement.
- Learn about how threat hunting benefits your organization, methods & tools used, and several tips.
- The first phase of the threat hunting cycle is defining the trigger.
Threat hunting is important because it helps organizations strengthen their security postures against ransomware, insider threats and other cyberattacks that might otherwise go unnoticed. Our elite team of hunters sift through endpoint event data from across CrowdStrike’s worldwide customer community to swiftly identify and stop highly sophisticated attacks that would otherwise go undetected. Fortunately, there are managed security solutions that have the right resources — the necessary people, data https://remedyalliance.com/2024/01 and analytical tools — to effectively hunt for unusual network activity and hidden threats. All of this takes time, resources and dedication — and most organizations aren’t adequately staffed and equipped to mount a continuous 24/7 threat hunting operation.
