NSA collects millions of text messages daily in ‘untargeted’ global sweep
The National Security Agency has collected almost 200 million text messages a day from across the globe, using them to extract data including location, contact networks and credit card details, according to top-secret documents.
The untargeted collection and storage of SMS messages – including their contacts – is revealed in a joint investigation between the Guardian and the UK’s Channel 4 News based on material provided by NSA whistleblower Edward Snowden.
The documents also reveal the UK spy agency GCHQ has made use of the NSA database to search the metadata of “untargeted and unwarranted” communications belonging to people in the UK.
The NSA program, codenamed Dishfire, collects “pretty much everything it can”, according to GCHQ documents, rather than merely storing the communications of existing surveillance targets.
The NSA has made extensive use of its vast text message database to extract information on people’s travel plans, contact books, financial transactions and more – including of individuals under no suspicion of illegal activity.
An agency presentation from 2011 – subtitled “SMS Text Messages: A Goldmine to Exploit” – reveals the program collected an average of 194 million text messages a day in April of that year. In addition to storing the messages themselves, a further program known as “Prefer” conducted automated analysis on the untargeted communications.
