In today’s digital landscape, cyber threats are becoming increasingly sophisticated and harder to detect. To counter these evolving threats, organizations must adopt proactive strategies, and one of the most effective ways to do so is through cyber threat hunting. Unlike traditional cybersecurity methods that rely on automated systems to detect known threats, threat hunting involves actively searching for hidden or unknown threats that have bypassed traditional defenses. At the heart of these efforts is the Security Operations Center (SOC), which serves as the central hub for monitoring and managing an organization’s security posture. In this article, we will explore the key phases of the cyber threat hunting process and highlight how ThreatMatrix, a leader in threat detection, can help streamline and enhance these efforts.
Preparation and Hypothesis Creation
The first phase of cyber threat hunting begins with preparation. Threat hunters need to set up a clear goal or hypothesis to guide their investigation. This involves identifying potential attack vectors, considering the current threat landscape, and analyzing past incidents.
Data Collection
In the preparation phase, the Security Operations Center (SOC) gathers relevant data from across the organization’s networks and systems. This includes event logs, network traffic, endpoint telemetry, and threat intelligence feeds. The SOC team uses this data to build an understanding of normal behavior within the network, which forms the baseline for identifying deviations.
Hypothesis Creation
Once the SOC team has gathered and analyzed this baseline data, the next step is to create a hypothesis. This is a well-informed assumption about where a potential threat might exist or how a potential attacker might operate within the network. The hypothesis could be based on suspicious network behavior, unusual login patterns, or even intelligence about recent attacks on similar organizations.
For example, ThreatMatrix enables organizations to leverage advanced analytics and threat intelligence to develop accurate hypotheses. Its platform provides real-time insights into attacker tactics, techniques, and procedures (TTPs), helping SOC teams refine their focus and improve the precision of their threat hunts.
Investigation and Data Analysis
Once the hypothesis is created, the next phase of cyber threat hunting is the investigation. This phase involves actively searching for signs of malicious activity based on the established hypothesis. Investigators comb through massive amounts of data looking for patterns, anomalies, or behaviors that deviate from the norm.
Data Filtering and Enrichment
The Security Operations Center (SOC) will use advanced data filtering tools to narrow down the scope of data to investigate. Rather than combing through all available logs, threat hunters target specific systems or events that are likely to yield useful information.
To help in this process, platforms like ThreatMatrix provide enriched threat intelligence, allowing SOC teams to cross-reference internal data with external threat feeds, known Indicators of Compromise (IOCs), and behavioral analytics. This enrichment helps hunters zero in on high-value data while minimizing noise.
Behavioral Analysis
During this phase, threat hunters use a combination of manual analysis and machine learning techniques to detect behaviors indicative of compromise. These could include lateral movement within the network, privilege escalation, or communication with command-and-control servers.
ThreatMatrix excels at this stage by offering powerful behavioral analytics tools. Its platform analyzes user and entity behavior to detect deviations from established baselines, helping SOC teams identify subtle signs of malicious activity that might otherwise go unnoticed.
Threat Detection and Validation
After patterns of suspicious activity are identified, the next step is threat detection and validation. During this phase, SOC teams must confirm whether the identified behavior is genuinely malicious or a false positive. This requires a combination of expertise, advanced detection tools, and threat intelligence.
Correlating Data
To accurately detect and validate threats, SOC analysts must correlate data from multiple sources. This might involve cross-referencing suspicious activities with known malware signatures, reviewing logs from other systems, or comparing current behaviors with historical data.
ThreatMatrix provides critical support during this phase by offering a consolidated view of the organization’s entire security posture. Its platform enables SOC teams to correlate threat intelligence, behavioral analytics, and endpoint data, making it easier to connect the dots and confirm the presence of a threat.
Threat Validation
Once a potential threat is identified, it must be validated. This involves determining whether the identified activity poses an actual risk to the organization. Validation might involve deeper investigation into the network traffic, forensic analysis of specific systems, or additional threat intelligence research.
ThreatMatrix’s validation tools make it easier for SOC teams to confirm threats and assess their severity. The platform’s real-time threat scoring system provides an instant assessment of the potential risk, helping organizations prioritize their response efforts and mitigate threats quickly.
Response and Mitigation
Once a threat is confirmed, the next phase of cyber threat hunting is response and mitigation. In this phase, SOC teams work to contain the threat, eliminate it from the environment, and ensure that similar incidents do not occur in the future.
Containment
The first step in the response phase is to contain the threat. Containment involves isolating the affected systems, cutting off communication between compromised devices, and preventing the threat from spreading further within the network. The goal is to limit the damage while a more thorough investigation takes place.
SOC teams can leverage ThreatMatrix’s automated containment capabilities to quickly quarantine affected systems and stop malicious activity in its tracks. By automating the containment process, organizations can reduce the risk of further compromise and protect critical assets.
Eradication
After containment, the next step is eradication. This involves completely removing the threat from the environment, whether by deleting malicious files, closing backdoors, or restoring systems from clean backups. SOC teams must also investigate how the threat gained access in the first place and take steps to close any security gaps.
ThreatMatrix’s platform integrates with a variety of endpoint detection and response (EDR) tools, enabling SOC teams to swiftly eradicate threats from the network. The platform also provides detailed reports that help organizations understand the root cause of the incident and prevent future occurrences.
Post-Incident Analysis and Reporting
Once the threat has been eradicated and normal operations are restored, the final phase of cyber threat hunting is post-incident analysis and reporting. This phase is crucial for understanding what went wrong, identifying areas for improvement, and ensuring that the organization is better prepared for future threats.
Incident Review
SOC teams conduct a thorough review of the incident, examining how the threat entered the network, what systems were affected, and how the response was carried out. This review helps identify any weaknesses in the organization’s defenses and informs the development of more robust security policies.
ThreatMatrix offers comprehensive reporting and analysis tools that make it easier for SOC teams to review incidents in detail. Its platform generates post-incident reports that highlight key findings, provide actionable insights, and offer recommendations for future threat hunts.
Knowledge Sharing and Process Improvement
Finally, the lessons learned from each incident must be documented and shared with the broader security team. This ensures that everyone is aware of the latest threats and the tactics used by attackers. Additionally, SOC teams should use this information to continuously improve their threat hunting processes.
ThreatMatrix encourages collaboration by providing a centralized platform where security teams can share intelligence, discuss incidents, and refine their threat hunting strategies. By fostering a culture of continuous learning and improvement, ThreatMatrix helps organizations stay ahead of emerging threats.
