“The United States’ National Security Agency intelligence-gathering operation is capable of accessing user data from smart phones from all leading manufacturers. Top secret NSA documents that SPIEGEL has seen explicitly note that the NSA can tap into such information on Apple iPhones, BlackBerry devices and Google’s Android mobile operating system.

Mini-programs, so-called “scripts,” then enable additional access to at least 38 iPhone features.

After the Canadian company acquired another firm the same year, it changed the way in compresses its data.
