Joe Brinkley

Joe Brinkley, also known in the community as BlindHacker, serves as the Director of Offensive Security Research & Community at Cobalt. Bringing over 20 years of "in the trenches" experience to the offensive security space, Joe’s career began in 2005 with a decade as a high-level government consultant before he transitioned into commercial penetration testing in 2016. He joined Cobalt in late 2025, drawn by a mission to evolve traditional Pentesting into a more dynamic, community-driven research model. When he isn't obsessing over cybersecurity, you’ll likely find him tinkering in his home lab or perfecting a smoked brisket.
