A study of the Athens affair, surely the most bizarre and embarrassing scandal ever to engulf a major cellphone service provider, sheds considerable light on the measures networks can and should take to reduce their vulnerability to hackers and moles.
It's also a rare opportunity to get a glimpse of one of the most elusive of cybercrimes. Major network penetrations of any kind are exceedingly uncommon. They are hard to pull off, and equally hard to investigate. (((Given the cozy relationship of AT&T and the NSA, isn't this statement a little ingenuous? Major network penetrations are a fact of life, not "exceedingly uncommon.")))
Even among major criminal infiltrations, the Athens affair stands out because it may have involved state secrets, and it targeted individuals—a combination that, if it had ever occurred before, was not disclosed publicly. The most notorious penetration to compromise state secrets was that of the “Cuckoo's Egg,” a name bestowed by the wily network administrator who successfully pursued a German programmer in 1986. The programmer had been selling secrets about the U.S. Strategic Defense Initiative (“Star Wars”) to the Soviet KGB. (((A punk-ass German hippie hacker – he wasn't anywhere near the league of these spooks loose in Athens. This wasn't a "hacker penetration," it was the big-leagues.)))
But unlike the Cuckoo's Egg, the Athens affair targeted the conversations of specific, highly placed government and military officials. Given the ease with which the conversations could have been recorded, it is generally believed that they were. But no one has found any recordings, and we don't know how many of the calls were recorded, or even listened to, by the perpetrators. Though the scope of the activity is to a large extent unknown, it's fair to say that no other computer crime on record has had the same potential for capturing information about affairs of state.
