Top-secret national security documents disclosed to the Guardian by Edward Snowden show United States and British intelligence have long attempted to crack the Tor anonymizer network used by human rights workers, journalists, cybercriminals and others.
On Friday, the Guardian published leaked documents attributed to the former intelligence contractor revealing how the US National Security Agency and Britain’s Government Communications Headquarters, or GCHQ, have worked extensively towards compromising the computers of people who browse the Internet with Tor, a program that routes traffic through multiple nodes in an effort to help mask the identities of its users.
