A group of crackers calling themselves MOD, or Masters of Downloading, say that since October of last year they've been exploiting unsecured connections to the Internet to successfully break into US computer systems that control military satellites.
What's more, the group appears to have stolen software that the US Department of Defense uses for monitoring and controlling the systems that make up the Defense Information Systems Network.
Screen shots of the software and interviews with members of MOD were posted at AntiOnline, a Web site that tracks high-profile computer break-ins.
In the interview, one of the group's 15 members says the software gives MODsters the ability to bring down the Defense Department's entire network. The unidentified cracker also noted that terrorists or governments would be interested in acquiring the data, but he said MOD has no intention of selling the information.
A Defense spokesperson said military officials are "aware of the intrusion and looking into the matter."
