Greg Hoglund
Michael Gregory "Greg" Hoglund is a recognized author, researcher, and serial entrepreneur in the cyber security industry. He is the founder of several companies, including Cenzic and HBGary. Hoglund contributed a great deal of early research to the field of rootkits, software exploitation, buffer overflows, and online game hacking. His later work focused on computer forensics, physical memory forensics, malware detection, and attribution of hackers. He holds a patent on fault injection methods for software testing, and fuzzy hashing for computer forensics. Due to an email leak in 2011, Hoglund is well known to have worked for the U.S. Government and Intelligence Community in the development of rootkits and exploit material. It was also shown that he and his team at HBGary had performed a great deal of research on Chinese Government hackers commonly known as APT (Advanced persistent threat). For a time, his company HBGary was the target of a great deal of media coverage and controversy following the 2011 email leak (see below, Controversy and email leak). Regardless, HBGary continued to grow and was successfully acquired by a large defense contractor.
