Three Fundamental Aspects of Being a Threat Hunter

This is the third article in our ongoing "The Rise of the Threat Hunter" blog series. For more information about the series, check out the introduction here or read last week's post, which dives deep into the excellent threat hunter research conducted by the CHISEL Group at the University of Victoria, here.

Structured yet adaptable: The backbone of threat hunting

A successful threat hunter should have a structured approach to their work. This includes a deep understanding of various threat hunting tools, advanced threat detection techniques, and methodologies for comprehensive threat analysis. A well-defined process ensures that no stone is left unturned while searching for potential threats. Structured threat hunters rely on frameworks and models such as the Cyber Kill Chain, MITRE ATT&CK, and the Diamond Model to guide their investigations. These frameworks provide a systematic approach to identifying and addressing different stages of an attack.

However, the ever-evolving nature of cyber threats requires adaptability. Cybercriminals continuously change their tactics, techniques, and procedures (TTPs) to avoid detection. A threat hunter must be flexible enough to adjust their strategies and methodologies. This adaptability allows them to quickly respond to new threat intelligence feeds and leverage the latest cybersecurity threat intelligence to improve their threat detection and response strategies. For example, when a new zero-day security vulnerability is discovered, an adaptable threat hunter can quickly incorporate this information into their threat hunting efforts and realign their focus to look for indicators of compromise (IOCs) associated with that vulnerability.

Situational awareness and well-informed: The eyes and ears of cybersecurity

Threat hunters must be situationally aware and well-informed about the current threat landscape. This involves continuously monitoring and analyzing threat intelligence feeds, staying up-to-date with the latest threat intelligence platforms, and understanding the specific threats their organizations or industries face. They should have a sharp awareness of the broader context in which they operate, including geopolitical events, industry-specific threats, and emerging cyber threats.

A situational threat hunter knows how to interpret data from various sources and relate it back to their organization's environment. They are experts in threat analysis, capable of identifying patterns and anomalies that could indicate a cyber threat. Being well-informed allows them to predict potential threats and take proactive measures to mitigate risks before they occur. For instance, if a new type of malicious software targeting financial institutions is discovered, a threat hunter in the financial sector would prioritize searching for indicators of compromise (IOCs) related to that malicious software within their networks.

Being well-informed also encompasses understanding the tools and technologies that threat hunters can use, which will be discussed further in later parts of this series.

Creative: The hidden weapon of a threat hunter

Creativity might not be the first characteristic that comes to mind when thinking about cybersecurity, but it is a crucial aspect of being a successful threat hunter. Cyber threat intelligence often involves thinking outside the box to detect and counter complex cyber threats. A creative threat hunter can develop innovative solutions and tactics to uncover hidden threats that automated systems might overlook. This creativity is essential for formulating hypotheses and testing them against real-world scenarios to uncover difficult-to-detect threats.

This creativity extends to the use of threat hunting tools and techniques. Whether they are developing custom scripts, utilizing advanced analytics, or employing unconventional methods to gather threat intelligence, a creative approach can make all the difference. Threat hunters can think like adversaries, anticipate their moves, and take effective countermeasures. For example, a creative threat hunter might set up honey pots or trap systems to lure attackers and gather valuable intelligence about their methods and objectives.

In Conclusion

Threat hunting is both an art and a science. The best threat hunters use their creativity to outsmart cyber adversaries while blending a structured yet adaptable approach with situational awareness and a well-informed perspective. As cyber threats continue to evolve, the demand for skilled threat hunters will only increase. Organizations that understand and develop these three key aspects can better protect themselves against the ever-present threats in the digital world.

Effective threat hunting is crucial for advanced threat detection and plays an important role in maintaining robust cybersecurity defenses. Whether you're a threat intelligence analyst or part of a cybersecurity team, developing these skills will enhance your ability to detect, analyze, and respond to threats, ultimately protecting your organization's digital assets.

Next week's post, titled "A Day in the Life of a Threat Hunter," will highlight what a typical day looks like for someone working as a threat hunter.
