A foreign computer intrusion two years ago reached classified Pentagon
computer networks, prompting a reorganization of offensive and defensive
cyberwarfare efforts, the commander of the new U.S. Cyber Command said
Army Gen. Keith Alexander, who is also director of the National Security
Agency (NSA), the electronic spying service, said in a speech that the
compromise took place in late 2008 in what he described as "a serious
intrusion into our classified networks."
As a result, the Pentagon combined two cyberwarfare units under NSA to
harmonize "offensive and defensive cybercapabilities" and build on NSA
intelligence work on "understanding of the threat and the ability to
respond to it," Gen. Alexander said in a speech to the Center for
Strategic and International Studies.
The four-star general provided no details on the classified information
Pentagon officials said later that Gen. Alexander was referring to the
compromise of classified networks through a computer "thumb" drive that
planted a virus into classified networks in the fall of 2008.
