We are TeamSIK (Security Is Key) – a group of people interested in IT-Security from Fraunhofer Institute for Secure Information Technology (Darmstadt, Germany). We meet up regulary in our spare time. Our main motivation is to work on interesting security-related projects for fun with the goal of exposing security issues. Currently, our main areas of interest are Android applications. We clearly want to state that all our finding are directly reported to the affected party and if needed we support them fixing the security issues. After a certain time frame (usualy after 90 days) we expose our findings on our website.

If this sounds interesting to you and you are located in Darmstadt feel free to contact us.
