Cyber Attack on U.S. Defense Department Computers Raises Concerns

Julian E. Barnes writes in The Los Angeles Times:

Senior military leaders took the exceptional step of briefing President Bush this week on a severe and widespread electronic attack on Defense Department computers that may have originated in Russia -- an incursion that posed unusual concern among commanders and raised potential implications for national security.

Defense officials would not describe the extent of damage inflicted on military networks. But they said that the attack struck hard at networks within U.S. Central Command, the headquarters that oversees U.S. involvement in Iraq and Afghanistan, and affected computers in combat zones. The attack also penetrated at least one highly protected classified network.

Military computers are regularly beset by outside hackers, computer viruses and worms. But defense officials said the most recent attack involved an intrusive piece of malicious software, or "malware," apparently designed specifically to target military networks.

"This one was significant; this one got our attention," said one defense official, speaking on condition of anonymity when discussing internal assessments.

Although officials are withholding many details, the attack underscores the increasing danger and potential significance of computer warfare, which defense experts say could one day be used by combatants to undermine even a militarily superior adversary.

Bush was briefed on the threat by Navy Adm. Michael G. Mullen, chairman of the Joint Chiefs of Staff. Mullen also briefed Defense Secretary Robert M. Gates.
