ThreatCat.ch has been founded in the autumn 2022 and consists of a bunch of experienced Cyber Threat Analysts and Incident Responders who have been working together for many years. We decided to create ThreatCat.ch to be able to serve the community by providing warnings and insights about emerging cyber threats. Occasionally we may also write about tools and tricks we have learned in our daily work life. And of course, ThreatCat.ch is about having fun doing interesting stuff together.
