I run a couple of honeypots which allow me to map some of the bad actors and scanners on the internet. The most popular honeypots are Dioanea, Cowrie (ssh, previously kippo) and Conpot (ICS). So far I’ve not really used this honeypot data that much for defensive purposes but a recent writeup on using ModSecurity and MISP gave me inspiration to transform this data into information that I can use as a defender.
The core … Read more.

There is not immediately an option within MISP to sync sightings between instances.You can sync … Read more.

Note that the purpose of the exercise is not to understand in detail every line of code in the malware. The analysis is done from an incident … Read more.
I published an article on IBM Security Intelligence on Raise the Red Flag: Guidelines for Consuming and Verifying Indicators of Compromise.
The articles covers how you can consume indicators of compromise (IOC) received via manual sharing. Although automatic sharing is preferred not all organisations have the resources to setup automatic sharing. Manual sharing is then a good fallback compared to not sharing at all.
The steps include source and content verification, context verification, sharing properties, … Read more.
Mid 2014 Symantec released a report on a threat actor Dragonfly targeting energy companies. Early September 2017 Symantec released an updated report on Dragonfly v2 where they describe that the threat actor shifted their attention from merely observing the environment to having remote access to the environment of energy providers.
This shift could indicate that the threat actor has a changed objective, from monitoring to actually intervening and potentially conducting sabotage.
I created two mindmaps … Read more.
