About D39's Vulnerability Research Finding

D39 has been focusing on vulnerability research and has identified several critical security flaws. We have found several vulnerabilities in Samsung Secure boot, which can break through Samsung Knox protections. In Black Hat USA 2020, we elaborated how did we discover and exploit the vulnerabilities in detail, demonstrated the exploit on a Samsung Galaxy S10 smartphone, and had a discussion on the possible impact of these vulnerabilities.
