Edward Snowden is back with one of the biggest revelations about the government's widespread surveillance program.
The US National Security Agency (NSA) and British counterpart Government Communications Headquarters (GCHQ) hacked into the networks of the world's biggest SIM card manufacturer, according to top-secret documents given to The Intercept by former NSA-contractor-turned-whistle blower, Edward Snowden.
OPERATION DAPINO GAMMA
The leaked documents suggests that in a joint operation, the NSA and the GCHQ formed the Mobile Handset Exploitation Team (MHET) in April 2010, and as the name suggests, the unit was built to target vulnerabilities in cellphone.
Under an operation dubbed DAPINO GAMMA, the unit hacked into a Digital security company Gemalto, the largest SIM card manufacturer in the world, and stole SIM Card Encryption Keys that are used to protect the privacy of cellphone communications.
Gemalto, a huge company that operates in 85 countries, creates about 2 Billion SIM cards each year for AT&T, T-Mobile, Verizon, Sprint and about 450 manufacturers worldwide. The SIM card manufacturer giant also produces banking cards, electronic passports, identification cards and other digital security solutions.
