hypothesis based hunting

Hypothesis hunting is a proactive hunting model that uses a threat hunting library. It's aligned with the MITRE ATT&CK framework and uses global detection playbooks to identify advanced persistent threat groups and malware attacks. Hypothesis-based hunts use the IoAs and TTPs of attackers.

Introduction. Structured threat hunting (often referred to as hypothesis-based hunting) remains one of the best ways that organizations can find previously undetected threats in their environment. It works so well because it structures the hunt around a central proposition, and at the end of the hunt, hunt teams can say, with a high degree of certainty, whether their organization has been ...

A hunting hypothesis is the foundation upon which your cyber detective journey is built. Think of it as the central hunch or educated guess that guides your investigation based on your intuition, experience, and research. Crafting a solid hunting hypothesis requires a delicate blend of creativity and analytical thinking.

Hypothesis-Based Hunting: Involves formulating hypotheses based on known threats or suspicious activities and actively investigating to confirm or refute them. IOC-Based Hunting (Indicators of Compromise): Focuses on searching for specific indicators that may indicate a security incident, such as IP addresses, file hashes, or patterns ...

recommendations for how hunting teams can implement a TTP-based approach. 1.1 Definition of Hunting . The word "hunting" is an emerging term within cybersecurity for which the exact definition is still evolving. In the 2017 Threat Hunting Survey, the SysAdmin, Audit, Network, and Security (SANS) Institute (Lee & Lee, 2017) defines threat ...

These hunting activities can draw on both intel- and hypothesis-based hunting models using IoA and IoC information. Hunting Frameworks There are a number of threat hunting frameworks organizations ...

Hypothesis Hunting: Hypothesis hunting is a proactive hunting methodology that employs a threat hunting library. It conforms to the MITRE ATT&CK framework and uses global detection playbooks to identify malware assaults and advanced persistent threat groups. Hypothesis-based hunting utilizes the IoAs and TTPs of attackers.

Proactive threat hunting uses the hypothesis-based model outlined above. An example of a hypothesis-based hunt would be using global threat intelligence to determine the kinds of cyberthreats most likely to be present in your network. This type of threat hunt might use a free, ...

Generating a Hypothesis. The process of threat hunting can be broken down into three steps: creating an actionable, realistic hypothesis, executing it, and testing it to completion. Though threat hunting can be aided by the use of tools, generating an actual hypothesis comes down to a human analyst.

Threat Hunting Hypothesis List #2: The Targeted Hunt. As your threat hunting capabilities evolve, you may want to consider honing in on specific adversaries and their associated tactics or techniques. Targeted hypotheses enable you to focus on well-known threat groups, providing a more in-depth and tailored approach to uncovering potential ...

Outcome: The hypothesis-based threat hunting process may lead to the identification of APT activities, allowing the organization to enhance its detection capabilities, isolate compromised systems ...

Hypothesis Based Hunting. Hypothesis hunting involves formulating hypotheses based on collected data and prior knowledge to narrow down the search for potential threats. This method typically begins with an analyst reviewing system data and identifying unusual behavior that may indicate malicious activity. The analysts then leverage their ...

Targeted Hunting Integrating Threat Intelligence Framework: Threat hunting based on assumptions is known as structured threat hunting. You develop a hypothesis, scope a hunting activity, and then carry out the hunt. Targeted hunting is a kind of hunting that comprises multiple phases and a clear understanding of what the hunters are searching ...

Threat hunting procedures vary based on an organization's needs and the capabilities of their security team, but commonly fall into one of three categories: structured hunting, unstructured hunting, or situational hunting. Structured hunting identifies and analyzes specific attacker behaviors and tactics, or IoA. It uses a hypothesis-based ...

Hunting requires the input of a human analyst and is about proactive, hypothesis-based investigations. The purpose of hunting is specifically to find what is missed by your automated reactive alerting systems. An alert from an automated tool can certainly give you a starting point for an investigation or inform a hypothesis, but an analyst ...

A threat hunting hypothesis is an informed assumption about a cyber-attack or any of its components. Just like in scientific research, in hypothesis-driven threat hunting, Threat Hunters make hypotheses the foundation of their investigations. Once a hypothesis is made, a Threat Hunter must take steps to test it.

Below is a diagram of the Hypothesis-Driven hunting process. This diagram serves as a valuable guide in illustrating the structured steps involved in each phase for the successful execution of the hypothesis-driven hunts within the PEAK Framework. Figure 1: The PEAK Hypothesis-Based Hunting Process. Prepare: Setting the Stage for Your Hunt ...

2. Situational awareness. 3. Domain expertise. Scaling up your threat-hunting model's maturity depends on many factors, but strong hypotheses play the most crucial role in this process. There ...

#2 Hypothesis Hunting. A proactive hunting method called hypothesis hunting makes use of a threat hunting library. It is in line with the MITRE ATT&CK framework and employs global detection playbooks to recognize malware attacks and advanced persistent threat groups. The IoAs and TTP of the attackers are used in hypothesis-based hunts.

Hypothesis-based threat hunting marks a paradigm shift from a reactive to a proactive approach. Instead of waiting for alerts or incidents to trigger a response, cybersecurity professionals take ...

Threat hunting is a proactive approach to threat prevention where threat hunters look for anomalies that can potentially be cyber threats lurking undetected in your systems. Combined with threat intelligence, hunting enables organizations to: ... Today there are several threat-hunting approaches: hypothesis-based, machine learning, baseline, AI ...

TL;DR Summary of the Threat Hunter's Hypothesis. • Organizations increasingly recognize the value of threat hunting, but hunting teams lack personnel, resources, and tools. • Unstructured threat hunting is a step up from reactive measures but lacks the consistency to disrupt threat groups' operations.

A ransomware attack is imminent based on increased chatter on underground forums. An adversary is using a specific spearphishing technique to gain initial access. ... Creating effective threat hunting hypothesis examples is a crucial aspect of successful threat hunting. By providing organizations and hunters with a starting point, a list of ...
