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.
I’m using OSSEC to feed an instance of TheHive to investigate security incidents reported by OSSEC. To better categorize the alerts and merge similar events, I needed to add more observables. OSSEC alerts are delivered by email with interesting information for TheHive. This was an interesting use case to play
TheHiveÂ is an awesome tool to perform incident management. One of the software components that is linked to TheHive is Cortex defined as a “Powerful observable analysis engine“. Let’s me explain why Cortex can save you a lot of time. When you are working on an incident in TheHive, observables are
I just published a new update of my imap2thehive tool. A quick reminder: this toolÂ is aimed to poll an IMAP mailbox and feed an instance ofÂ TheHiveÂ with processed emails. This new version is now able to extract interesting IOCs from the email body and attached HTML files. The following indicators are
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
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
I just published a quick update of my imap2thehive tool. Files attached to an email can now be processed and uploaded as an observable attached to a case. It is possible to specify which MIME types to process via the configuration file. The example below will process PDF & EML
TheHive is a great incident response platform whichÂ has the wind in its sails for a while. More and more organization are already using it or are strongly considering to deploy it in a near future. TheHive is tightly integrated with MISP to push/pull IOC’s. Such tool must be fed with
