Ang Cui is a PhD Student. His research is currently focus is on embedded devices such as home and corporate routers and cell phones. He is the primary inventor of a novel host-based defense mechanism known as Symbiotic Embedded Machines. SEMs are designed specifically to retrofit black-box, vulnerable legacy embedded systems with sophisticated anti-exploitation mechanisms. Over the past 3 years, Ang has been actively quantifying the extent of the embedded threat in real-world environments, developing novel exploitation techniques for embedded systems such as enterprise networking equipment and developing practical defenses for embedded systems which constitutes our global communication substrate. His current projects include: Symbiotic Embedded Machines and Vulnerable Embedded Device Scan.
