About Me

I am a final year PhD candidate at University of Chinese Academy of Sciences(UCAS), my advisor is Prof. Wei Zou, my co-advisor is Xiaorui Gong. I am currently a Research Scientist at Pennsylvania State University, under supervision of Dr. Xinyu Xing. I received Bachelor degree from Department of Information Security, University of Science and Technology of China(USTC) in 2014. My current research interest is exploitation automation as well as knowledge driven approaches for vulnerability analysis.

I started participating various CTF competitions since 2015 and here is my blog about CTF games and research experience. I play with CTF team Never Stop Exploiting(NeSE), a top Chinese CTF team. I play DEFCON 2018 final with Tea Delivers.

Awards:

National Cyber Security Award 2016.

National Scholarship for graduate student 2015.

CVEs I found:

Integer underflow in libbpg, CVE-2017-8906

Heap overflow in libbpg, CVE-2017-8909
