The Rise of the Threat Hunter: Common Mistakes and Challenges

In an era where cyber threats loom large, the role of threat hunters has become increasingly vital. Our ongoing series, “The Rise of the Threat Hunter,” has delved into the intricacies of what threat hunters do and the skills they employ. This week, we turn our focus to two prevalent mistakes that threat hunters often make and the three significant challenges they face, as highlighted in a recent study by the University of Victoria. Understanding these pitfalls and obstacles is crucial, as they can lead to wasted time and resources, ultimately increasing organizational risk.

Two Common Threat Hunting Mistakes

As the headlines scream of high-profile data breaches and cyberattacks, it’s easy to see how threat hunters might fall into certain traps. Two of the most common mistakes are overestimating the severity of anomalies and misidentifying benign activities as threats.

Overestimating Threat Severity

When faced with any deviation in data, threat hunters are trained to investigate. However, not all anomalies carry the same weight. A minor security gap can easily be mistaken for a significant data breach. This overestimation can lead to unnecessary alarm, diverting critical resources away from genuine threats.

In large organizations, the consequences of this mistake can be particularly pronounced. Focusing excessively on minor anomalies can result in alert fatigue, where the sheer volume of alerts desensitizes threat hunters. This fatigue can cause them to overlook genuine threats, wasting valuable time and resources on non-issues instead of proactive threat hunting and enhancing security measures.

False Positives

Another significant challenge is the difficulty in distinguishing between malicious activity and harmless errors. Insider threats, for instance, can stem from both malicious users and those who inadvertently mishandle their credentials. The challenge of false positives is exacerbated by the vast amounts of data that threat hunters must sift through.

False positives not only consume time but can also erode trust in threat detection systems. Repeated false alarms can lead to hesitancy in decision-making and slower response times. Investigating these false positives often requires extensive log analysis and collaboration across departments, straining resources and reducing overall efficiency. As alert fatigue sets in, the risk of overlooking genuine threats increases, making it imperative to improve detection accuracy and minimize false positives.

Recognizing these common mistakes is the first step toward enhancing threat hunting practices. However, these issues often stem from broader, systemic challenges that threaten the effectiveness of threat hunters.

Top Three Challenges

The mistakes of overestimating threat severity and dealing with false positives are often symptoms of deeper issues. The following three challenges create an environment where these mistakes are more likely to occur.

Tooling Issues

Threat hunters rely on a variety of tools, which can be broadly categorized into technical and non-technical categories. Technical tools assist in the actual threat hunting process, while non-technical tools support tasks like note-taking and reporting.

However, many threat hunters report significant disadvantages with their existing tooling. Common complaints include a lack of cohesion between tools, poor performance, and ineffective visualizations. These issues can lead to missed threats and wasted time as hunters struggle to correlate results across disconnected systems.

Time to Focus

Threat hunters often find themselves juggling multiple tasks, from administrative duties to client-related responsibilities. This constant context switching can severely hinder their ability to focus on critical threat hunting activities.

Moreover, threat hunters typically collaborate with various internal and external stakeholders. Without standardized handoff protocols, communication can become convoluted, further complicating their efforts to maintain focus and efficiency.

Organizational Roadblocks

Despite the critical importance of threat hunting, many teams encounter internal resistance. Resource allocation is a common issue, but cultural challenges can also play a significant role. Not all teams within an organization prioritize security, and some may even withhold information about potential threats, creating silos that hinder effective threat hunting.

Overcoming Threat Hunting Challenges

To enhance the effectiveness of threat hunting, it is essential for organizations to support their threat hunters. Addressing the challenges they face can help mitigate common mistakes and improve overall security posture.

Ironically, a significant part of the solution lies within the first challenge: tooling. The right tools can make a substantial difference in a threat hunter’s ability to detect anomalies and prioritize threats effectively. An integrated toolset can streamline processes, save time, and foster trust between threat hunters and the broader organization they serve.
