COSTELLO: A six-year investigation by an American security firm reports it observed a group of hackers called the "Common Crew," stealing information from hundreds of organizations and firms worldwide. It says the hackers were apparently connected to the Chinese government. CNN's David McKenzie is keeping an eye on this from Beijing. Good morning, David.</s>DAVID MCKENZIE, CNN INTERNATIONAL CORRESPONDENT: Morning, Carol. Yes, it's quite extraordinary. Most of those 140 companies that Mandian, the Virginia-based company said were attacked were in fact in the U.S., including national security companies like aerospace companies, high-tech, I.T. They say that this group of hackers, not just tens, but hundreds potentially working out of Shanghai in China saying that they were not just working alone, they were working in cooperation with the Chinese military. And in fact, under direction from the Chinese government here in Beijing, it's a very serious allegations of terra bytes, hundreds of terra bytes of cooperate espionage, spying done from here in China -- Carol.</s>COSTELLO: I mean, what can the United States do about this?</s>MCKENZIE: The United States, particularly senators and congressmen in the committees, which look at this have said for some time now that the next real threat could be a cyber threat. Not necessarily just a nuts and bolts terrorist attack, but attacks coming from state- responsive groups and hacking groups. Mandian, the U.S. company, said that the way that these attacks happened say that it had to be state-sponsored. The Chinese government for their part is denying it saying that this is rubbish and in fact that they are getting attacked. So certainly tit for tat arguments are going across from China and the U.S. definitely not the last we've heard of this -- Carol.</s>COSTELLO: David McKenzie, thanks so much, reporting live from Beijing. There's a big concern right now, could we soon see our skies filled with drones? Not just military and police aircraft, but drones that happen to belong to your neighbor? And your neighbor could fly those drones over your house. I will ask one outspoken drone owner why he needs one.
