LAS VEGAS: #CTF--GMO Internet Group, Inc. (TOKYO: 9449), a global leader in internet infrastructure and security headquartered in Tokyo, will send a group-wide team to compete in the Capture The Flag (CTF) competition at “DEF CON 34,” the world’s premier security conference, to be held August 6–9, 2026 in Las Vegas, USA.
