Yesterday, a very interesting article was published on the MISP blog by my friend Koen about a solution to monitor a MISP instance with Cacti. Monitoring your threat intelligence platform is always a good idea because many other tools depend on it. You can feed other tools with MISP data
[SANS ISC] Simple Blacklisting with MISP & pfSense
I published the following diary on isc.sans.edu: “Simple Blacklisting with MISP & pfSense“: Here is an example of a simple but effective blacklist system that I’m using on my pfSense firewalls. pfSense is a very modular firewall that can be expanded with many packages. About blacklists, there is a well-known
MISP Summit 0x05 Wrap-Up
I’m in Luxembourg for a full week of infosec events. It started today with the MISP summit. It was already the fifth edition and, based on the number of attendees, the tool is getting more and more popularity. The event started with a recap of what happened since the last
[SANS ISC] Querying DShield from Cortex
I published the following diary on isc.sans.edu: “Querying DShield from Cortex”: Cortex is a tool part of the TheHive project. As stated on the website, it is a “PowerfulÂ Observable Analysis Engine”. Cortex can analyze observables like IP addresses, emails, hashes, filenames against a huge (and growing) list of online services.
[SANS ISC] The real value of an IOC?
I published the following diary on isc.sans.org: “The real value of an IOC?“: When a new malware sample is analysed by a security researcher, details are usually posted online with details of the behaviour and, based on this, a list of IOCs or â€œIndicators of Compromiseâ€ is published. Those indicators
[SANS ISC] Automatic Hunting for Malicious Files Crossing your Network
I published the following diary on isc.sans.org: “Automatic Hunting for Malicious Files Crossing your Network“: If classic security controls remain mandatory (antivirus, IDS, etc), it is always useful to increase your capacity to detect suspicious activities occurring in your networks. Here is a quick recipe that Iâ€™m using to detect
Splunk Custom Search Command: Searching for MISP IOC’s
While you use a tool every day, you get more and more knowledge about it but you also have plenty of ideas to improve it. I’m using Splunk on a daily basis within many customers’ environments as well as for personal purposes. When you have a big database of events,
[SANS ISC Diary] IOC’s: Risks of False Positive Alerts Flood Ahead
I published the following diary on isc.sans.org: “IOC’s: Risks of False Positive Alerts Flood Ahead“. Yesterday, I wrote a blog post which explained how to interconnect a Cuckoo sandbox and the MISP sharing platform. MISP has a nice REST API that allows you to extract useful IOC’s in different formats.
Quick Integration of MISP and Cuckoo
With the number of attacks that we are facing today, defenders are looking for more and more IOC’s (“Indicator of Compromise) to feed their security solutions (firewalls, IDS, …). It becomes impossible to manage all those IOC’s manually and automation is the key. There are two main problems with this
Running MISP in a Docker Container
MISP (“Malware Information Sharing Platform“) is a free softwareÂ which was initially created by the Belgian Defence to exchange IOC’s with partners like the NCIRC (NATO). Today it became an independent project and is mainly developed by a group of motivated people. MISP is mainly used by CERT’s (“Computer Emergency Response
