A high-ranking colonel deep within Air Force Cyberspace Command tells me his folks lost a Predator unmanned aircraft on April 4 to an elite squad of Al Qaeda hackers.  "The only way they could have destroyed the UAV (unmanned aerial vehicle) is to have used a highly classified DAOS (distributed accrual of service) attack.  We suspect they acquired a KG-175A device from an underground reseller at the local bazaar near Balad air base."  The colonel couldn't tell me anything else, as it was all highly classified.
