Security Researcher
I am currently working for LG Electronics as a security researcher,
and I have a 9 years of work experience in security area.
From LG, I am performing penetration testing on embedded SWs,
and developing automated methods for detecting vulnerabilities.
Moreover, I am also developing security features which are adopted in smartphones and vehicle components.
The security features that I am developing include secure boot, secure storage, crypto services, and simlock.
Basically, my research work focuses on mobile & system security and program analysis.
I am interested in finding new vulnerabilities using static and dynamic analysis methods.
