http://arstechnica.com/security/2013/12 ... o-zombies/Serial hacker Samy Kamkar has released all the hardware and software specifications that hobbyists need to build an aerial drone that seeks out other drones in the air, hacks them, and turns them into a conscripted army of unmanned vehicles under the attacker's control.
I love this idea, it is a simple hack, I have used all the technology they are using for the hack (Ie other than the quadcopter), but it will work reliably and quickly to hack any drone of that model. The army drones will be a bit harder, but we have already seen they are hackable. Anything is hackable.
