evious diary (Unity Makes Strength
), I briefly mentioned MISP(which means Malware Information Sharing Platform). Since this tool is becomingmore and more popular, Id like to give more details about it.Sharing is key could be the slogan of MISP. The ideais to allow different organizations to share IOCs (Indicators of Compromize) like IP addresses, domains, hashes, URLs, filenames, ... Thegoal is to increase their ability to protect themselves against malicious activities. With millions of new samples spread in the wild everyday, new domain generation algorithms (DGAs) and ever-changing C2 topologies, its mandatory to join our forces to fight the bad guys.">">The core components of MISP are classic: a database and a web interface which looks like a classicticketing system where people can manage their IoC">But, with the growing amount of data to manage, the key is automation. MISP has many ways to be interconnected to 3rd party systems. How?MISP offers a great REST API to manage IOCs in both ways.">In the other way, manual input of new IOCs can be a real pain. They can be">Directly from some">

Im running a local MISP instance which is synchronized with other ones. Ill receive automatically new IOCsbut all my locally created data will be spread to my peers. But, even if sharing is key, there are always some data that must remain inside an organization for multiple purposes. Some organizations will not share all information with me and same for me.">Today, MISP is more and more deployed and used by CERTs but also private organizations who need to increase their ability to detect malicious activity on their networks.The official MISP website is: misp-project.org.If you want to test it, Im also maintaining a Docker container ready to use.And you? Do you already use MISP? How did you integrate it within your defense layers?Would you be interested to have access to a MISP instance?">">Xavier Mertens
