It seems that the "old technologies" are approaching their end. This guy got caught by having too many physical contacts: -- walking into the Soviet embassy (well-known to be under surveillance) -- presumably using dead drops to exchange documents and money -- relying on a physical contact with an unknown person (whom he thought to be KGB, incorrectly) Digital dead drops and digital cash will eventually revolutionize spying. The digital dead drops are here now, though not the digital cash. --Tim May Tuesday October 13 11:49 AM EDT Ex-U.S. Army Analyst Arrested On Spy Charges WASHINGTON (Reuters) - A former U.S. Army intelligence analyst has been arrested on charges of spying for Russia by allegedly passing to KGB agents highly classified documents from 1988 to 1991, federal law enforcement officials said Tuesday. They said David Sheldon Boone, who worked for the military's super-secret National Security Agency, was scheduled to appear in federal court in Alexandria, Virginia, later Tuesday. According to the criminal complaint, Boone, who was arrested Saturday, began spying in 1988 after he walked into the Soviet embassy in Washington and volunteered his services. He was charged with meeting his Russian handler about four times a year between late 1988 and when he retired from the Army in 1991. Boone allegedly was paid more than $60,000 for the highly sensitive, top-secret documents he gave them. He allegedly gave the Russians documents about the capabilities and movements of Soviet forces and about Soviet tactical nuclear weapons. He also allegedly gave the Russians a document based on information that the National Security Agency, which conducts eavesdropping operations around the world, had intercepted. Boone was arrested after he was contacted in September by an individual who worked on behalf of the FBI, but whom he believed to be a Russian agent. According to the complaint, he had agreed to resume his espionage activities.
