VinnieLiu

Before Bishop Fox had a single invoice, before the pitch decks and the term sheets and the 390-person team, there was a teenager in Kentucky reading Phrack on IRC and learning to think like an attacker. Vinnie Liu did not stumble into cybersecurity. He was recruited - literally - through the channels where the early hacker scene lived.

Liu found out about an NSA program through his IRC connections - a path for high school graduates with an aptitude for cryptology, mathematics, or computer science. At 17, he became a full-time NSA analyst while simultaneously attending college, splitting his time between Langley-adjacent intelligence work and the University of Pennsylvania campus. He describes feeling like "the lowest guy on the totem pole" among people who were, in his words, exceptionally talented.

After Penn (Class of 2001, Pi Kappa Alpha), Liu moved through the private sector the way someone does when they already know what they're after: Ernst & Young Advanced Security Centers, then Honeywell International, where he led the Global Security unit's Attack & Penetration team. At Honeywell, he met Francis Brown. The two spent their off-hours moonlighting on penetration tests for Fortune 100 clients.

In Q3 2005, Liu and Brown decided the moonlighting was the point. Bishop Fox was born - not in a garage but in a living room in Arizona, as a side hustle that became something else entirely.

Long before the speaking circuit, Liu was in the stacks - co-authoring books that became standard references in the offensive security field. The Hacking Exposed series was exactly what the title implied: methodical, practitioner-level guides to understanding how attackers think, written by people who were actually doing the attacking.

Liu has contributed to seven books in total, including Hacking Exposed Wireless and Hacking Exposed Web Applications. He continues as a contributing columnist at Dark Reading, and has presented at Microsoft BlueHat, Black Hat, and DEF CON.
