Kyriakos has a BSc in Computer Science and an MSc in Information Security. Deeply interested in the analysis and the reverse engineering of commercial/custom packers and software protections for the last 6 years, he was a speaker in Athcon 2011 and also the author of the Reversing Challenges for 2011 and 2012 for Athcon conference. Except from taking them apart, he also has a deep interest in studying anti-reversing tricks and creating his own custom tricks that go from simple debugger detection to custom obfuscation and other anti-analysis mechanisms for the sake of imagination and creativity. More recently, he has moved into the area of malware research/analysis at Sophos as a Thread Researcher. Kyriakos spends some of his free time developing his own reversing tools, as well as experimenting with C++ and Asm.
