Gemalto, the world's largest sim card manufacturer, is checking the latest documentation provided by The Intercept. The document, which was provided by former NSA employee Ed Snowden, noted that the NSA, in conjunction with GCHQ (the United Kingdom Government Communications Headquarters), had hacked into Gemalto's internal computer network, stealing keys to protect the privacy of global mobile communications. These keys enable the intelligence agencies to decrypt voice and data-form mobile communications without authorization or eavesdropping, or even to unlock encrypted communications that were intercepted but not decrypted. Users, network operators and the government will not know.

It is reported that GCHQ 2010 secret documents in detail recorded the cyber incident. The NSA named the theft program X-keyscore. With Gemalto operations in 85 countries, customers include around 450 wireless network providers around the world, including At&t, T, Verizon and Sprint, producing about 2 billion SIM cards a year, The move gives the NSA and GCHQ the ability to secretly monitor most of the world's mobile communications. In 2009 they had the ability to crack 12 million to 22 million secret keys per second, according to the NSA's confidential documents.

Gemalto said it had no knowledge of the infiltration of intelligence agencies in the United Kingdom and the US into its system. At this stage, it is not yet possible to determine whether the document is true, but the company takes the information seriously and makes every effort to conduct an in-depth investigation.

"There are other ways to hack into the network for 2G networks, but the 3G, 4G, and LTE networks are not easy to crack, so the key is particularly important," says Green, a Johns Hopkins University's password-cracking expert. ”
