National Security Agency (NSA)

US intelligence officials used Twitter to send "nearly a dozen" coded messages to a Russian spy who claimed to have in his possession the National Security Agency (NSA) data stolen by the hacking group called Shadow Brokers, the media reported. The Russian was known to American and European officials for his ties to Russian intelligence and cybercriminals -- two groups suspected in the theft of the NSA and the Central Intelligence Agency (CIA) hacking tools in the past, The New York Times reported this week.
