The FUNT (shorten from Fast and UNTraceable) is a cryptokey used to hack electronic computer systems. It is only spotted in game files and not implemented in the game.

In-game description
"This powerful cryptokey is considered to be one of the highest caliber hacking tools available. Long rumored to have been originally designed for Advocacy use, these difficult to acquire devices have only recently been making its way into the hands of criminals. Most who have used them say they are worth the effort to acquire. With the cryptokey's official Advocacy designation unknown, the name FUNT is a shortening of the device's common descriptor - 'fast and untraceable.'"
