The first Black Hat was held July 7-10, 1997 in Las Vegas, immediately prior to
DEF CON 5. The conference was aimed at the computer industry, promising to give them privileged insight into the minds and motivations of their hacker adversaries. Its organizers stated: "While many conferences focus on information and network security, only the Black Hat Briefings will put your
engineers and software
programmers face-to-face with today's cutting edge computer security experts and '
hackers'." It was presented by DEF CON Communications and Cambridge Technology Partners. It was founded by
Jeff Moss, who also founded DEF CON, and is currently the Conference Chair of the Black Hat Review Board. Black Hat started as a single annual conference in
Las Vegas,
Nevada, and is now held in multiple locations around the world. At Black Hat USA in 2005,
Cisco Systems tried to stop Michael Lynn from speaking about a
vulnerability that he said could let
hackers virtually shut down the Internet. Black Hat Briefings was acquired by
CMP Media, a subsidiary of U.K.-based
United Business Media (UBM) in 2005 which was then acquired by
Informa Tech in June 2018. After a corporate reorganization in 2025, Black Hat Briefings was moved to the Informa Festivals division. Conference attendees had been known to hijack wireless connections of the hotels, hack hotel television billing systems, and in one instance, deploy a fake
automated teller machine in a hotel lobby. ==Components==
