Sean Gallagher /
Sean Gallagher is a former IT editor and national security editor at Ars Technica. A University of Wisconsin grad, he wrote his first program in high school on a DEC PDP-10, and his first database app on a dual-floppy Apple II. Sean's first paid writing gig was producing "supplemental content" for Microprose's Gunship 2000 and F-117 Stealth Fighter 2.0 game manuals. A former naval officer, Sean served aboard the USS Iowa (BB-61) and at a river patrol boat squadron— where discovery of his computer skills landed him the assignments of network administrator and computer security officer. Aside from a few dark years as a systems integrator and a stint as Ziff Davis Enterprise's director of IT strategy, Sean was either in the review lab or on a tech beat for nearly 30 years. He is now Principal Threat Researcher at SophosLabs.
