The Guardian reports: Britain is exporting surveillance technology to countries run by repressive regimes, sparking fears it is being used to track political dissidents and activists.

The UK’s enthusiastic role in the burgeoning but unregulated surveillance market is becoming an urgent concern for human rights groups, who want the government to ensure that exports are regulated in a similar way to arms.

Much of the technology, which allows regimes to monitor internet traffic, mobile phone calls and text messages, is similar to that which the government has controversially signalled it wants to use in the UK.

The campaign group, Privacy International, which monitors the use of surveillance technology, claims equipment being exported includes devices known as “IMSI catchers” that masquerade as normal mobile phone masts and identify phone users and malware – software that can allow its operator to control a target’s computer, while allowing the interception to remain undetected.

Trojan horse software that allows hackers to remotely activate the microphone and camera on another person’s phone, and “optical cyber solutions” that can tap submarine cable landing stations, allowing for the mass surveillance of entire populations, are also being exported, according to the group.
