I am an independent information security researcher. I have worked as an IS researcher in Positive Technologies, Vupen Security, CISS. I like writing exploits, especially for Windows NT Kernel. I won the PHDays Hack2Own contest in 2011 and 2012. I tried to hack Google Chrome during Pwnium 2 but failed. I have published a few papers about kernel mode drivers and their exploitation. I am currently, engaged in reverse engineering research and vulnerability search automation.
