North Korea was indeed behind the cyberattacks that targeted dozens of Web sites in the U.S. and South Korea over the past week, a U.S. defense official told Fox News Wednesday afternoon. The unnamed Pentagon official added that the attack did not penerate the Department of Defense's computer systems, which are constantly being probed from outside. Some defense officials complained privately that the Department of Homeland Security was taking the lead on protecting government agencies from cyber attacks, and yet the Pentagon wasn't informed about the attacks until Wednesday — by hearing about it from the media. Another source told Fox News that the attacks actually began a week ago, not Saturday as previously reported. • Click here to learn how a brute-force cyber attack works. • Cli
