Sim CardThe stolen encryption allowed the agencies to decode data that passes between mobile phones and cell towers all over the world, the website says

US and British intelligence agencies illegally hacked into a major manufacturer of Sim cards to steal codes and facilitate eavesdropping on mobiles, a US news website says.

The Intercept website said that the information came from former American intelligence contractor Edward Snowden.

The company allegedly targeted - Gemalto - says it is taking the allegations "very seriously".

It operates in 85 countries and has more than 40 manufacturing facilities.

The Intercept says that "the great Sim heist" gave US and British surveillance agencies "the potential to secretly monitor a large portion of the world's cellular communications, including both voice and data".

It says that among the clients of the Netherlands-based company are AT&T, T-Mobile, Verizon, Sprint and "some 450 wireless network providers around the world".

Highly embarrassing

The Intercept claims that the hack organised by Britain's GCHQ and America's National Security Agency took place in 2010. Neither agency has commented on the allegations.

TabletsExperts say that the alleged hack is a major compromise of worldwide mobile phone security

The stolen encryption allowed the agencies to decode data that passes between mobile phones and cell towers. They were able to un-garble calls, texts or emails intercepted out of the air.

A Gemalto spokeswoman told the Reuters news agency that while the company was not targeted "per se", there was "an attempt to try and cast the widest net possible to reach as many mobile phones as possible".

"We take this publication very seriously and will devote all resources necessary to fully investigate and understand the scope of such highly sophisticated techniques to try to obtain Sim card data," she said.

Correspondents say that the revelations are highly embarrassing for the agencies, because they give the impression that they will do whatever is required to improve their surveillance powers, even if that means stealing data from law-abiding Western firms.

Gemalto makes Sim cards for mobile phones and furnishes service providers with encryption codes to keep the data on each phone private.

The Intercept claims that by first cyber-stalking employees at Gemalto and then penetrating their emails, the spy agencies were able to steal thousands of encryption keys at source.

The BBC's Naomi Grimley in Washington says that this would allow them to eavesdrop easily on phone calls and texts without seeking permission from telecoms companies or foreign governments, and without leaving a trace.

The Intercept cites as its source documents leaked by Edward Snowden, the former NSA contractor who is currently living in Russia.
