About me
I founded A3 Security Consulting, the first security consulting company in South Korea, in 1999. I was also a member and the last leader of KUS (KAIST UNIX Society), the legendary hacking group in South Korea (KUS is regarded as a former group of KAIST GoN).
I am a professor at the School of Cybersecurity, Korea University. (Very proudly, I am listed in the Stanford/Elsevier's world top 2% scientist, 2024). At Korea University, I'm a director of HCRL, a well-known automotive security dataset contributor. My research is focused on solving many security problems using AI and Machine Learning in automotive security and online gaming areas. Especially, the dataset for machine learning based IDPS for in-vehicle networks is well noticed to the automotive security researchers.
As a serial entrepreneur, I am a co-founder of AI Spera, which provides Criminal IP service (cyber threat intelligence search engine) globally. Before joining Korea University, I was a technical director (TD) and the head of the information security department of NCSOFT (2004-2010).
Here are several keywords that describe me well at each age.
1st age (before 1999): "a whitehat hacker in Korea", system administrator, UNIX expert, Daejeon Science High School, KAIST, KAIST UNIX Society (KUS), System Programmers’ Association for Researching Computer Systems (SPARCS)
