Military US Base Systems In Afghanistan And Iraq Hit By A Virus, At Least One Classified Network Penetrated

The ‘malware’ strike, thought to be from inside Russia, hit combat zone computers and the U.S. Central Command overseeing Iraq and Afghanistan. According to a report from Washington, the incursion 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. The invasive software, known as agent.btz, has circulated among nongovernmental U.S. computers for months. But only recently has it affected the Pentagon’s networks. It is not clear whether the version responsible for the cyber-intrusion of classified networks is the same as the one affecting other computer systems.

The malware is able to spread to any flash drive plugged into an infected computer. The risk of spreading the malware to other networks prompted the military to ban the drives.

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.

Military electronics experts have not pinpointed the source or motive of the attack and could not say whether the destructive program was created by an individual hacker or whether the Russian government may have had some involvement. Defense experts may never be able to answer such questions, officials said.

Suspicions of Russian involvement come at an especially delicate time because of sagging relations between Washington and Moscow and growing tension over U.S. plans to develop a missile defense system in Eastern Europe. The two governments also have traded charges of regional meddling after U.S. support for democratic elections in former Soviet states and recent Russian overtures in Latin America.

The offending program has been cleansed from a number of military networks. But officials said they did not believe they had removed every bit of infection from all Defense Department computers.
