The U.S Central Command is now infected with the worm and a high-classified network has been hit also.
It is unclear if the author of the article thinks that an infection is the same things as an ‘attack’ though. From the article:
“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.”
This infection has been report at the beginning of the month. This might just be sensationalism ofrcomplete ignorance from the author who might think than an infection by a worm made in Russia is a deliberate attack.
Officials would not describe the exact threat from agent.btz, or say whether it could shut down computers or steal information. Some computer experts have reported that agent.btz can allow an attacker to take control of a computer remotely and to take files and other information from it.
