$15 billion is estimated by US intelligence officials to have been lost in 2009 due to cyber espionage. The issue was a subject of the recent report issued by the office of the director of National Intelligence to raise awareness of the threat of cyber spying. Report says China has been the key culprit. Russia has also been named as a source of theft. Wayne Rash,a writer for eWEEK and Washington bureau chief, believes China is aggressively going after data that they can use – some for military advantage but in a variety of cases to commercial advantage. However, he sees no indication that Russia breaks into computers or networks to gain commercial advantage for its companies.
