Threat Hunting: Proactively Detecting Hidden Cyber Threats

"Threat Hunting" is a specialized cybersecurity methodology aimed at identifying threats that might evade standard security monitoring protocols. This proactive technique aims to uncover concealed or undetected security risks, going beyond routine security protocols.

Cyber Threat Hunting

Establishing a Hypothesis

A hypothesis, derived from comprehensive threat modeling, focuses on higher probability and potentially high-impact events to guide threat hunting activities.

Profiling Threat Actors and Activities

Threat hunting enables the observation and tracking of potential threat actors' behaviors and tactics, encompassing their strategies for privacy and evasion to bypass detection systems.

An Example of a Threat Hunting Scenario

Let's envision an internal threat hunting scenario within a company:

A company identifies an unusual network traffic pattern that evades standard security monitoring tools, indicating a possible significant attempt at breaching data security. Consequently, the security team launches an extensive threat hunting operation to trace the origin and intention of this pattern. Through hypothesis formulation and detailed log analysis, they uncover that this abnormal traffic signifies an insider's attempt at breaching data security. This revelation becomes a crucial step in refining existing security measures and monitoring systems.

This article delves into scenarios demonstrating potential attackers' methodologies in unauthorized entry attempts and the scope of their objectives. Threat hunting leverages specialized tools designed for regular security monitoring and incident response.

What Can We Analyze During Threat Hunting?

• Analyzing network traffic: Assessing network traffic patterns to detect potential threats.

• Analyzing the executable process list: Examining how attackers interact with executable processes to infiltrate or manipulate systems.

• Analyzing other infected hosts: Investigating potential threats' propagation and their impact on other systems.

• Identifying the execution of malicious processes: Understanding the initiation and execution of malicious processes within the system.

• 
  

While executing threat hunting requires significant resources and time, it offers several notable benefits:

• Boosting detection capabilities: Identifying and intervening in abnormal system activities.

• Minimizing attack surface: Recognizing and neutralizing potential attack routes.

• Preventing attack vectors: Thwarting unauthorized access and mitigating potential attacks.

• Recognizing critical assets: Defining and safeguarding critical assets more effectively.
