Hunting Malicious Infrastructure using JARM and HTTP Response

In this blog, I will explain my hunting methodology with two practical examples. My process starts always looking for the first node in phase one, analyzing and escalation in phase two, and results in phase three.

This article explains a hunting methodology for malicious infrastructure using JARM and HTTP Response hash. The two examples used are QBot C2 and Brute Ratel C4. Despite the differences between the two, the same methodology can be used to hunt them.

The JARM (JSON Artifact Repository Model) is a data model that allows for the storage of artifacts in a structured way. It is used to store the data collected from the HTTP response hash. The HTTP response hash is a method of collecting data from the response of a web request. It is used to identify malicious infrastructure.

The article then goes into detail about how to use the JARM and HTTP response hash to hunt for malicious infrastructure. It explains how to use the JARM to store the data collected from the HTTP response hash. It also explains how to use the HTTP response hash to identify malicious infrastructure.

The article then provides two practical examples of how to use the JARM and HTTP response hash to hunt for malicious infrastructure. The first example is QBot C2, which is a type of malware that is used to steal data from computers. The second example is Brute Ratel C4, which is a type of malware that is used to launch distributed denial-of-service (DDoS) attacks.

The article concludes by summarizing the hunting methodology and providing a few tips for using the JARM and HTTP response hash to hunt for malicious infrastructure. It also provides a few resources for further reading.

Overall, this article provides a detailed explanation of how to use the JARM and HTTP response hash to hunt for malicious infrastructure. It provides two practical examples and a few tips for using the methodology. It is a useful resource for anyone looking to hunt for malicious infrastructure.
