Ed Snowden has revealed to the Guardian that the GCHQ ( Government Communications Headquarters) in the United Kingdom, which is responsible for the security of key government communications and systems, had spied on foreign officials at two G20 summits in London back in 2009. The story, which broke on June 16, stated that:
the disclosure raises new questions about the boundaries of surveillance by GCHQ and its American sister organisation, the National Security Agency, whose access to phone records and internet data has been defended as necessary in the fight against terrorism and serious crime. The G20 spying appears to have been organised for the more mundane purpose of securing an advantage in meetings. Named targets include long-standing allies such as South Africa and Turkey.
There have often been rumours of this kind of espionage at international conferences, but it is highly unusual for hard evidence to confirm it and spell out the detail. The evidence is contained in documents – classified as top secret – which were uncovered by the NSA whistleblower Edward Snowden and seen by the Guardian. They reveal that during G20 meetings in April and September 2009 GCHQ used what one document calls "ground-breaking intelligence capabilities" to intercept the communications of visiting delegations.
• Setting up internet cafes where they used an email interception programme and key-logging software to spy on delegates' use of computers;
• Penetrating the security on delegates' BlackBerrys to monitor their email messages and phone calls;
• Supplying 45 analysts with a live round-the-clock summary of who was phoning who at the summit;
• Targeting the Turkish finance minister and possibly 15 others in his party;
• Receiving reports from an NSA attempt to eavesdrop on the Russian leader, Dmitry Medvedev, as his phone calls passed through satellite links to Moscow.
The documents suggest that the operation was sanctioned in principle at a senior level in the government of the then prime minister, Gordon Brown, and that intelligence, including briefings for visiting delegates, was passed to British ministers.
There's a reason why government secrecy is toxic. It makes everyone paranoid.
