- US Government to Pay $2 Million for Automatic Hacking and Patching System. From Softpedia. At this year’s DEF CON security conference scheduled to be held in Las Vegas at the start of August, the Defense Advanced Research Projects Agency (DARPA) will be giving away a total of $4 million to seven teams participating in the Cyber Grand Challenge (CGC). Started in 2014, the Cyber Grand Challenge is a classic CTF (Capture The Flag) competition, but with a kink. Instead of pinning two teams of security researchers against each other in an attempt to hack and/or protect a network or device, the CGC will have the seven teams battle using automated computer programs that are built to hack other systems and to automatically detect and fix weaknesses on their own.
