Perpetrators are using Web sites in China to breach computer networks in the Department of Defense (DoD) and other U.S. agencies, according to U.S. officials.
While classified systems have not yet been breached, officials are concerned because bits of information pieced together can provide an enemy with useful windows into the U.S. government’s methods, U.S. officials told the Washington Post.
Government officials characterized the scope of the hacks, which have been occurring for the last few years, as “surprisingly big,” according to the Post. The perpetrators are also trying to hack into the State, Energy and Homeland Security departments.
