Eireann Leverett once found 10,000 vulnerable industrial systems on the internet.

He then worked with Computer Emergency Response Teams around the world for cyber risk reduction.

He likes teaching the basics, and learning the obscure.

He continually studies computer science, cryptography, networks, information theory, economics, and magic history.

He is also fascinated by zero knowledge proofs, firmware and malware reverse engineering, and complicated network effects such as Braess' and Jevon's Paradoxes. He has worked in quality assurance on software that runs the electric grid, penetration testing, and academia. He likes long binwalks by the hexdumps with his friends.

Eireann Leverett is a regular speaker at computer security conferences such as FIRST, BlackHat, Defcon, Brucon, Hack.lu, RSA, and CCC; and also a regular speaker at insurance and risk conferences such as Society of Information Risk Analysts, Onshore Energy Conference, International Association of Engineering Insurers, International Risk Governance Council, and the Reinsurance Association of America. He has been featured by the BBC, The Washington Post, The Chicago Tribune, The Register, The Christian Science Monitor, Popular Mechanics, and Wired magazine.
