Sebastian Neef is a security researcher at heart. At the age of 14, he discovered the security side of things and has been interested in it ever since. During his A-levels he became a freelancer in this field and started to consult various companies, including well known ones by participating in their bug bounty programs since 2012. Web and IoT topics are his core strengths and his research about sensitive files on web servers or exposed waterworks or wind power stations has been featured by popular German media in broadcasts as well as print. Neef likes to share his knowledge by either writing blog posts, giving conference talks or teaching students at the university’s hacker club (“AG Rechnersicherheit”). Also enjoys playing CTFs with ENOFLAG. 2019 he co-authored a book about IT security and is currently finishing his CS master degree at TU Berlin.
