Hacking the Predator drone: Cheaper than dinner and a movie

1 Predator drone: $4.5 million

Intercepting video from the Predator drone's unprotected communications link: $25.95

Predator drones are built by General Atomics Aeronautical Systems Inc. of San Diego. Some of its communications technology is proprietary, so widely used encryption systems aren't readily compatible, said people familiar with the matter.

Fixing the security gap would have caused delays, according to current and former military officials. It would have added to the Predator's price. Some officials worried that adding encryption would make it harder to quickly share time-sensitive data within the U.S. military, and with allies.

Today, the Air Force is buying hundreds of Reaper drones, a newer model, whose video feeds could be intercepted in much the same way as with the Predators, according to people familiar with the matter. A Reaper costs between $10 million and $12 million each and is faster and better armed than the Predator. General Atomics expects the Air Force to buy as many as 375 Reapers.
