Threat hunting can be categorized into-&nbsp;<\/span><\/span><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Structured_Threat_Hunting\"><\/span><span style=\"color: #000000;\"><strong>Structured Threat Hunting<\/strong><\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"font-weight: 400; color: #000000;\">Structured threat hunting is carried out by using IOAs (Indicators of Attack) to gain an understanding of techniques that could be used by attackers. The approach to this type of threat hunting is based on the methodologies previously chosen by the attackers. In other words, structured threat hunting is driven by a particular technique or methodology.<\/span><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Unstructured_Threat_Hunting\"><\/span><span style=\"color: #000000;\"><strong>Unstructured Threat Hunting<\/strong><\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"font-weight: 400; color: #000000;\">It is primarily based on IOCs (Indicators of Compromise), whose approach is triggered. The threat hunter looks for triggers based on a particular indicator, which is devised using post- and pre-detection behavior. Unstructured threat hunting can be useful for data retention.<\/span><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Situational_Threat_Hunting\"><\/span><span style=\"color: #000000;\"><strong>Situational Threat Hunting<\/strong><\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"font-weight: 400; color: #000000;\">This is an exhaustive set of procedures that is mainly based on the internal risk and vulnerabilities of the organization. This type of threat hunting involves data from assessments of previous attacks to check whether anything similar might happen again.&nbsp;<\/span><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Methodologies_for_Detecting_Threats\"><\/span><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-7849\" src=\"https:\/\/threatcop.com\/blog\/wp-content\/uploads\/2022\/01\/Types-of-Threat-Hunting.webp\" alt=\"Types of Threat Hunting\" width=\"1602\" height=\"1018\" srcset=\"https:\/\/threatcop.com\/blog\/wp-content\/uploads\/2022\/01\/Types-of-Threat-Hunting.webp 1602w, https:\/\/threatcop.com\/blog\/wp-content\/uploads\/2022\/01\/Types-of-Threat-Hunting-300x191.webp 300w, https:\/\/threatcop.com\/blog\/wp-content\/uploads\/2022\/01\/Types-of-Threat-Hunting-1024x651.webp 1024w, https:\/\/threatcop.com\/blog\/wp-content\/uploads\/2022\/01\/Types-of-Threat-Hunting-768x488.webp 768w, https:\/\/threatcop.com\/blog\/wp-content\/uploads\/2022\/01\/Types-of-Threat-Hunting-1536x976.webp 1536w, https:\/\/threatcop.com\/blog\/wp-content\/uploads\/2022\/01\/Types-of-Threat-Hunting-80x51.webp 80w, https:\/\/threatcop.com\/blog\/wp-content\/uploads\/2022\/01\/Types-of-Threat-Hunting-500x318.webp 500w, https:\/\/threatcop.com\/blog\/wp-content\/uploads\/2022\/01\/Types-of-Threat-Hunting-800x508.webp 800w\" sizes=\"auto, (max-width: 1602px) 100vw, 1602px\" \/><br><strong>Methodologies for Detecting Threats<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"font-weight: 400; color: #000000;\">In the previous section, we discussed types of threat hunting where a collective approach was taken. Those collective approaches can be elementally divided into the following methodologies. The significance of the methodologies described below is to showcase how a particular attribute or parameter can be effectively used for threat hunting and prevention.&nbsp;<\/span><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Investigation_of_Indicators\"><\/span><span style=\"color: #000000;\"><strong>Investigation of Indicators<\/strong><\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"font-weight: 400; color: #000000;\">Whenever any cyber attack is carried out, it exposes loopholes in cyber security infrastructure and human intelligence. This methodology is based on a tactical approach to leverage threat intelligence. Information and collective outcomes are logged in IOCs and IOAs. Then, this catalog is used as a trigger during threat hunting. The triggers reveal the exploitation within the system or the ongoing cyber attacks.<\/span><\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"IOCs_Indicators_of_Compromise\"><\/span><span style=\"color: #000000;\"><strong>IOCs (Indicators of Compromise)<\/strong><\/span><span class=\"ez-toc-section-end\"><\/span><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"color: #000000;\"><span style=\"font-weight: 400;\">It is a catalog that contains a set of identifications of the vulnerabilities found in the system. It is inclusive of all the vulnerabilities that have been found in that category of that particular cyber attack till date. For example, recently the Log4j library was found with vulnerabilities (<\/span><span style=\"color: #183994;\"><a style=\"color: #183994;\" href=\"https:\/\/www.kratikal.com\/blog\/log4shell-zero-day-vulnerability-in-log4j\/\" rel=\"noopener\"><b>log4shell<\/b><\/a><\/span><span style=\"font-weight: 400;\">) in input validation, which was updated with a patch. Furthermore, it was again found with another vulnerability, and an upgraded patch came. Such vulnerabilities become IOCs for the log4j library.&nbsp;<\/span><\/span><\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"IOAs_Indicators_of_Attack\"><\/span><span style=\"color: #000000;\"><strong>IOAs (Indicators of Attack)<\/strong><\/span><span class=\"ez-toc-section-end\"><\/span><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"font-weight: 400; color: #000000;\">IOAs differ from IOCs in a few ways. These indicators are positioned from the point of attack, which is yet to happen. In simpler words, it is a proactive approach when a vulnerability is already executed and a prevention step is taken before the threat becomes real or when a cyber attack is executed. In other words, IOAs fill the remaining gap left by IOCs during threat prevention and hunting. IOAs are responsible for alerting authorities before a cyber attack is attempted.&nbsp;<\/span><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"An_Investigation_Based_on_Hypothesis\"><\/span><strong>An Investigation Based on Hypothesis<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"font-weight: 400; color: #000000;\">A hypothesis is an assumption based on a certain explanation regarding a particular thing that is about to happen. In cybersecurity, there is a possibility of threat hunting through investigating a hypothesis. There are three ways in which the hypothesis can be investigated.<\/span><\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><span style=\"color: #000000;\"><strong>Analytics-based hypothesis:<\/strong><span style=\"font-weight: 400;\"> There is a massive amount of data available for analysis on cyber attacks dating back to at least 20 years. This process involves the usage of data analysis concepts and machine learning algorithms to develop artificial intelligence tools for threat detection and suggesting prevention measures. The use of analytics helps in developing hypotheses consisting of UEBA (User and Entity Behaviour Analytics). UEBA is used for developing hypotheses for identifying or predicting threats based on aggregate risk scores. <\/span><\/span><\/li>\n\n\n\n<li><span style=\"color: #000000;\"><strong>Intelligence-based hypothesis:<\/strong><span style=\"font-weight: 400;\"> It involves the analysis of threat vectors such as <\/span><\/span><span style=\"color: #183994;\"><strong><a style=\"font-size: revert; color: #183994;\" href=\"https:\/\/www.kratikal.com\/blog\/malware-the-new-age-weaponry\/\" target=\"_blank\" rel=\"noopener\">malware<\/a><\/strong><\/span><span style=\"font-weight: 400;\">, <span style=\"color: #000000;\">email threats, <\/span><\/span><span style=\"color: #000000;\"><span style=\"color: #183994;\"><strong><a style=\"font-size: revert; color: #183994;\" href=\"https:\/\/www.kratikal.com\/blog\/perfect-phishing-attack-a-penetration-testers-perspective\/\" rel=\"noopener\">phishing<\/a><\/strong><\/span><span style=\"font-weight: 400;\">, viruses, worms, etc. It includes intelligence reports on risks and attack vectors that are developed by vulnerability scanning, malware analysis, phishing analysis, email analysis, etc. Using comprehensive intelligence, a hypothesis of a possible threat is predicted.<\/span><\/span><\/li>\n\n\n\n<li><span style=\"color: #000000;\"><strong>Situation-based hypothesis:<\/strong><span style=\"font-weight: 400;\"> Every organization has an internal team that carries out an enterprise risk assessment, or they can hire third-party organizations to carry out <\/span><span style=\"color: #183994;\"><strong><a style=\"font-size: revert; color: #183994;\" href=\"https:\/\/www.kratikal.com\/managed-security-services.php\" target=\"_blank\" rel=\"noopener\">VAPT<\/a><\/strong><\/span><span style=\"font-weight: 400;\"> (Vulnerability Assessment and Penetration Testing) to identify possible loopholes and vulnerabilities in security.\u00a0<\/span><\/span><\/li>\n<\/ol>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Machine_Learning_or_Intel-Based_Investigation\"><\/span>Machine Learning or Intel-Based Investigation<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"font-weight: 400; color: #000000;\">The notion of &#8220;intel&#8221; in cybersecurity is said to be the source of intelligence that is gathered across networks to evaluate the parameters of security against set standards. This intelligence can be IOCs, IP addresses, domain names, hash values, etc. Considering the human-based vulnerabilities, it can also be employee assessment.&nbsp;<\/span><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"font-weight: 400; color: #000000;\">All this intelligence can be used comprehensively with previous or general statistics on cybersecurity data to develop machine learning integrated tools.

In the process of threat hunting, the role of indicators, analytics-based hypotheses, and intelligence is prominent to learn about triggers. Thus, a trigger is the exact point in the cyber attack where malicious activity begins.<\/span><\/span><\/li>\n\n\n\n<li><span style=\"color: #000000;\"><strong>Investigation:<\/strong><span style=\"font-weight: 400;\"> In this step, the technology of Endpoint Detection and Response (EDR) is used through multiple tools.

These security tools and services must collect all the data for every activity. The collective information is crucial for future threat prevention. Thus, threat hunting is itself a procedure of enhancing threat intelligence, which will be used to develop automated systems.&nbsp;<\/span><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"font-weight: 400; color: #000000;\">Threat hunting is important not only as a defense mechanism but also to provide information for future development. Threat hunting is itself based on huge amounts of data, and that\u2019s why it is quite effective at securing the cybersecurity infrastructure. It acts as both a defense wall and an automated system that guards the wall.&nbsp;<\/span><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Comparison_with_Threat_Intelligence\"><\/span><span style=\"color: #000000;\">Comparison with Threat Intelligence<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"font-weight: 400; color: #000000;\">Threat intelligence is another term that is used in cybersecurity. The significance of threat intelligence is that it&#8217;s a database of information about successful intrusions or cyber attacks. The collection of data in this database is done mainly through automated security systems. In addition to this, vulnerability assessment and penetration testing data are also fed into the database. All of this data is comprehensively analyzed using machine learning and artificial intelligence.<\/span><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"font-weight: 400; color: #000000;\">Threat intelligence is extensively used in threat hunting. It means that threat intelligence is a fundamental necessity to carry out threat hunting. Threat intelligence is used as an essential database that provides parameters for threat hunting tools to prevent cyber attacks.<\/span><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Hunting_Models\"><\/span><span style=\"color: #000000;\">Hunting Models<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"font-weight: 400; color: #000000;\">Threat hunting involves an ocean of processes, approaches and techniques with the goal of detecting and preventing cyber intrusions. A threat hunting model is specified using a defined approach with inputs from processes, logs, and packets.&nbsp;<\/span><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"font-weight: 400; color: #000000;\">Then, it is fed with information about a particular attack vector. This helps in devising a specific threat hunting model. In common words, one can say that a threat hunting model is basically based on the application of threat detection and prevention. The following are some standard categories of threat hunting models.<\/span><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Intel-based_Threat_Hunting\"><\/span><span style=\"color: #000000;\">Intel-based Threat Hunting<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"font-weight: 400; color: #000000;\">This model of hunting incorporates intelligence from IOCs. This model is reactive in approach, and its rules are defined by threat intelligence consisting of analytics and hypotheses. The investigation step provides the most crucial information that is used while developing this model.&nbsp;<\/span><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"font-weight: 400; color: #000000;\">Apart from IOCs, this model also takes in domain names, IP addresses, hash values, or other details gathered from the host. They are collected in the form of intelligence and retrieved from a platform in a specific way to be used in this model.<\/span><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Hypothesis-Based_Threat_Hunting\"><\/span><span style=\"color: #000000;\">Hypothesis-Based Threat Hunting<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"font-weight: 400; color: #000000;\">The hypothesis is mainly a predictive kind of threat hunting model. Its approach is proactive, and a threat library is used to develop the model. This model incorporates IOAs and TTPs (attackers\u2019 behavior) from threat intelligence for formulating hypotheses. Thus, a set of procedures is curated based on a particular hypothesis that is delivered using this model.<\/span><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Customized_Threat_Identification\"><\/span><span style=\"color: #000000;\">Customized Threat Identification<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"font-weight: 400; color: #000000;\">We\u2019ve already talked about the methodologies, types, and steps of threat hunting separately based on their significance and application. The custom threat hunting model is a framework that takes a certain attribute from each of those segments based on the requirement. Threat hunters mostly use threat intelligence databases to develop some standard custom model that is specific to a particular industry or organization. Along with that, the cybersecurity team in the company is always ready to develop a customized model when a certain attack is launched and all the security mechanisms have failed.<\/span><\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter\"><img decoding=\"async\" src=\"https:\/\/media.giphy.com\/media\/v7WM6sLcnGIc8\/giphy.gif\" alt=\"Matrix of Cybersecurity\"\/><\/figure>\n<\/div>\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Be_Proactive_and_Safeguard_Your_Organisation\"><\/span>Be Proactive and Safeguard Your Organisation<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><span style=\"font-weight: 400; color: #000000;\">Every organization spends a significant amount of money to implement a cybersecurity framework in their organization.
