What secret does snowden know?

Mr Snowden claims that, to date, he has revealed less than 10 per cent of the information he already has.Snowden, a former cia intelligence analyst and contractor for the national security agency, stole more than 1.5 million classified N.S.A. documents.Since June 2013, some of his files have been exposed.Among the secrets already known to the world are the following:

The United States has monitored some 122 international dignitaries, the embassies of 38 countries, numerous international organizations including the United Nations and many international conferences, such as the G8 and G20 summits.They also monitored the cellphone conversations of ordinary citizens in many countries, including Norway, the Netherlands, Belgium, France, Spain, Italy, the Vatican, Russia and the Middle East.

Britain and the United States have a joint project, code-named "subversion".The two partners, the UK's directorate of communications and the us national security agency, share data, information and other intelligence.Britain's directorate of communications has hacked into fibre-optic cables across the world, easily intercepting the data they want.

The nsa has a program codenamed "tailor made operation," which organizes a group of top hackers to infiltrate computer terminals around the world to obtain the information they need, or to use malware and viruses to attack the individuals and systems they want to attack.In 2011 alone, the N.S.A. launched 231 targeted cyberattacks.

The proverbial prism program, which combines American Internet giants such as Google, Microsoft, apple, facebook, and others, mines and USES user data on all of these Internet platforms.Using a tool called digital men in black, they can tell almost everything people do on the Internet, including chatting, shopping, and searching.

In addition to the UK, the us also works with countries such as Canada, Sweden, Germany, Israel, Australia and Indonesia to intercept hundreds of millions of short messages and hundreds of millions of emails every day.The data is what the agency calls "a gold mine for personal data mining."And phone and computer encryption, in the agency's view, is not at all an obstacle to their access to information.
