Edward Snowden ισχυρίζεται ότι η NSA και η GCHQ κατάφεραν να παραβιάσουν τα δίκτυα της Gemalto, the world's largest SIM card manufacturer. With this particular hack, they gained access to the encryption keys of the cards.
The hack as we mentioned above was carried out by a team of NSA and GCHQ. The information about the attack revealed by a 2010 GCHQ document.
Gemalto manufactures SIM cards for companies AT&T, T-Mobile, Verizon, Sprint and many more. In total it manufactures cards for around 450 telecommunication providers worldwide.
According to his leak Edward Snowden, stolen encryption keys allow secret services to monitor unlicensed mobile communications from phone companies. They also overshoot the need for a warrant and intercept without leaving traces that can be detected by wireless providers.
Gemalto, for her part, says she did not know about the hack until it was published by Intercept.
"I'm very upset and worried about what has happened," said Paul Beverly, Gemalto 's executive vice president. "What I want you to understand is what kind of impact it will have on any of our customers."
