In 2021 he reverse-engineered, proved the existence and devastated an NSA crypto backdoor. Currently he is quietly working on reverse-engineering and breaking another NSA backdoor. Sometimes he does pro-bono audits, like for the attribute-based credential system IRMA by the privacybydesign.foundation.
He is very much dedicated to digital policy, like copyright, privacy and all the other related topics, the culmination of his activities in Brussels is the most comprehensive free database on the European Parliament at parltrack.eu, which has helped the advocacy of such groups as EDRi, Corporate Europe Observatory, Transparency International.
Stefan initiated the founding of the hackerspace in Budapest, Hungary, he likes to think he also had some influence on the founding of the Bratislava and Prague hackerspaces, but that might be disputed. He is also one of the initial organisers of Camp++ a small hackercamp in Hungary, which was started after a alcohol-heated argument with one of the orga of the dutch OHM camp in 2013, and has been successfully organized every year since then.
