Geeks win millions for teaching computers to battle each other

The event, known as the Cyber Grand Challenge, concluded Thursday evening in a Las Vegas convention center ballroom after a digital battle among software programs running on seven supercomputers on a stage in a Las Vegas ballroom.

Thousands of geeks watched as announcers presented a play-by-play account of the competition. It took place ahead of Friday's start of Def Con, a hacking convention expected to draw more than 20,000 people to two sprawling Las Vegas convention centers.

The hacking competition was sponsored by DARPA, or the Defense Advanced Research Projects Agency, the U.S. military laboratory credited with creating the Internet.

DARPA dubbed it the world's first "capture the flag" hacking contest played solely by computers.

Its goal was to stimulate development of technologies for automating the process of protecting computer networks against cyber attacks.

Previous DARPA contests include one for self-driving vehicles that is widely credited with kick-starting the now robust autonomous-vehicle industry.

The hacking challenge included 96 rounds in which computers were charged with examining software programs, identifying bugs, patching them and finding ways to attack rival machines.

DARPA said it hoped the contest would speed the slow process of identifying and patching real-world bugs. It can take more than a year from the time a vulnerability is uncovered until a vendor releases a software patch, according to DARPA.

That delay gives hackers time to attack unprotected systems, one factor that security experts say has contributed to the surge in cyber attacks.

"Mayhem" was provisionally named winner of the competition. Organizers said they would review the results overnight and confirm the results on Friday.

The winning program was created by a team of eight computer experts from San Francisco and Pittsburgh, Pennsylvania, who are affiliated with Carnegie Mellon University.

Mayhem will compete with teams of humans in the Def Con capture the flag contest, which starts on Friday. It is the first time the elite competition has included a computer.

Second place went to a program dubbed Xandra, created by security experts from the University of Virginia and GrammaTech Inc, earning them a $1 million prize.

A program known as Mech Phish, which was born at the University of California, placed third, earning its creators $750,000.
