For several years the FIRST SecLounge SIG has been organizing Capture The Flag (CTF) challenges during the annual FIRST conference and due to the pandemic this year's challenge had to move online. Three members of CERT.at participated and we scored the 9. place of 42 teams. This is a writeup of the challenges we solved.

The newest IntelMQ release 2.3.3 comes with various error corrections and supports a bunch of new feeds provided by the non-profit Shadowserver.

Domain Names are the center piece of locating services on the internet and they can be used for a variety of purposes and services. Understanding the type of services a Domain Name offers is one of the key aspects of Internet Security. In another post last year we already introduced tag2domain, our tagging / labelling framework for domain names that helps us to better understand this landscape of services and software.

This IntelMQ version did not gain any major features and is a sole product maintenance release. It covers various minor error corrections in the IntelMQ software, and usability enhancements for the new API. We thank all contributors who participated in this release!
