Building Unexploitable Systems!
Dr. Yeongjin Jang is an elite cybersecurity researcher. He hacks CPU, OS, iPhone, IoT devices, and anything that is operated by computers. He is interested in trustworthy computing, vulnerability discovery and analysis, side-channel attack and defense, developing new exploit primitives, mobile security, practical applied cryptography, jailbreaking, and ‘buidl’ing defense mechanisms.
His prior research projects covered in popular media including: MIT Technology Review, Forbes, Reuters, CNN, CBS News, Wired, Telegraph, and many more.
In addition to the academic works, he has been enjoying playing capture-the-flag (CTF) contests. He is fortunate to be an advisor of OSUSEC, the team advanced to the DEF CON 30 CTF Final in 2022, and he received the Black Badge(s) from DEF CON, as the winner (team DEFKOR) of DEF CON 23 CTF (2015) and the winner (team DEFKOR00t) of DEF CON 26 CTF (2018).
