This is essentially a part of Cyber Threat Intelligence (CTI). If you have observed specific IOCs on your system and initiated the incident response process, you might want to delve deeper into a particular IOC to understand who is targeting you. Incorporating IOCs into OSINT analysis can therefore enrich your data, improve threat detection, contextualize threats, and enable proactive defense. They can lead us to more contextual information which helps us gain a deeper understanding of potential threats. IOCs can be valuable for OSINT investigations as they provide specific clues related to malicious activities. IOCs are Valuable for OSINT Investigations 🔗︎ In that case, it is possible that the same threat actor might be responsible for the IOCs you’re investigating. Suppose a particular attack or campaign has already been attributed to a specific threat actor. IOCs help track threat actors because some can be linked to previous attacks or campaigns.

By parsing through logs and extracting IOCs, you can reconstruct the incident’s sequence of events, solving the puzzle of what happened. IOCs come in different forms, such as IP addresses, file hashes, domain names, URLs, and more.Ī typical application of Indicators of Compromise (IOCs) during incident response arises following a cyberattack. IOCs are artifacts or clues left behind after a cyberattack that you can observe on your system to determine if your system has been compromised. Understand the Scope and Impact of an Attack with IOCs 🔗︎ Threat Intelligence Feeds Put IOCs into ContextĪdvancing Your Security Measures to a Proactive Level Use Regex to Analyze Unstructured Data and Spot Patterns Identify Traces of Threat Actors from Attack Associations and Shareable IOCsĪttribute IOCs to Threat Actors through Malware and Infrastructure IOCs are Valuable for OSINT Investigations Understand the Scope and Impact of an Attack with IOCs The role of threat intelligence feeds in keeping your teams informed about new threats.Tips on using regular expression (regex) to identify patterns indicating a threat actor.The use of IOCs in open source intelligence (OSINT) investigations.In this article, we will cover the following topics:

This allows you to identify specific indicators of compromise (IOCs) within systems during incident response and comprehension of the targets. By utilizing open source information (OSIF) and threat intelligence feeds, you can incorporate cyber threat intelligence into your defense strategies. As attacks grow in complexity, it’s imperative to keep your guard up against potential threats.įortunately, there are more and more methods for gathering information about attacks and attackers. Organizations constantly wage battles against malicious actors who seek to exploit vulnerabilities and infiltrate their digital defenses at any given time. Moving from Vulnerability to Vigilance 🔗︎
