The latest documents from the National Security Agency leaked by Edward Snowden show that government spies are capable of listening in on mobile phone calls that use a common form of encryption, according to a Washington Post report.

The Post on Friday published confidential government documents provided by Snowden that show that the NSA can “process” cellular phone calls on GSM networks, even if they are encrypted. GSM, which stands for Global System for Mobile communications, is the world’s most widely used cellphone technology — though several large networks, notably Verizon and Sprint, rely on an older network technology called CDMA.

Smith pledged to “pursue a comprehensive engineering effort to strengthen the encryption of customer data across our networks and services.” That includes major communications, productivity, and developer services such as Outlook.com, Office 365, SkyDrive, and Windows Azure.
