Did you see this? http://www.wired.com/dangerroom/2011/10/drone-virus-kept-quiet/
Don’t think its a Worm. The thinking is the Worm is some monitoring software installed by some branch of US Gov,just never reported to people who need to know. Taking the drone over the way Iranian is describing, is much simply technically than the Worm. So my bet is the Iranian is not BS’ing. The classified networks are Air Gabbed,even if you have Worm on it you can’t control it real-time to do bad stuff.
