It was revealed last week that the GCHQ and the NSA conducted a joint operation that resulted in the theft of thousands of encryption keys from the world’s largest manufacturer of cellphone SIM cards which may have granted the two spy agencies access to the communication information of millions of people. The company, known as Gemalto, has been playing damage control ever since and, while it hasn’t denied that the hack occurred, it claims that things aren’t as bad as they seem. Many cybersecurity experts beg to differ, however.
