The F5 CTF Badge

Badge CTF

F5's debut into badgelife : blinkies, badge-tagging, hidden keys, and a CTF built right in. Game on.

Flip the slide switch for a 3-second sneak preview. Complete fun challenges to earn your bragging rights and light up your badge with maximum LEDs.

Explore F5 partner booths at Black Hat 2025 to progressively unlock sections of your badge.

To submit CTF flags, press and hold the CTF key, then enter the flag in binary using the 1 and 0 switches. Press and hold the MODE key to change the LED blinking pattern.

Every challenge reveals a binary flag. Submit the correct flag to instantly unlock that challenge's LEDs on your badge. Challenges can be completed in any order.

To reset your CTF progress, press and hold both the 1 and 0 keys simultaneously for a few seconds.
