Description is important while creating an IoC, since open IoC is developed to be used by everyone, and if you create an IoC, it is better to write enough description to understand by others. Creating IoC with Mandiant IOCeĭo not forget that attributes you choose should be unique to the file, so it can be detectable and less false positives occur. We tried to show some of them in the screenshot below. Then, we can add more attributes from hundreds of items in IOCe. Additionally, we add File Name in OR logic. The collaborative threat exchange was created partly as a counterweight to criminal hackers successfully working together and sharing information about viruses, malware and other cyber. MD5 and SHA256 values of WinSCP.exe fileįrom Item > File Item menu, we choose File MD5 and paste the MD5 value of the file. Founded in 2012, OTX was created and is run by AlienVault (now AT&T Cybersecurity), a developer of commercial and open source solutions to manage cyber attacks. Let’s check hash values of WinSCP.exe file first. As the example, we will create IoC for detecting WinSCP file. Firstly, IOCe provides us to give a name and description for the IoC. We start from File > New > Indicator menu. It is also so easy to create IoC with Mandiant IOCe. Here, we can see all the IoCs we downloaded and if we want we can change, delete or add IoCs in that file. Later in this post, we will create IoC with different attributes also.Īfter we download the IoCs as xml file, from File > New > Indicator From File menu and choose the xml file. They can contain a lot of different attributes about the attack, but in this example, we only have hash values. This is an xml file downloaded and has 108 IoCs containing 36 MD5, 36 SHA1, and 36 SHA256 hash values. This is the IoCs of malicious files found on Pulse Connect Secure devices. So, as example, we download an IoC from Open Threat Exchange. Here, we will show a simple example to view an existing IoC. First of all, Mandiant IOCe could be used to view open IoCs which you downloaded from different sources. In this post, we will mention on Mandiant IOC Editor.
