“It’s no (longer a) secret that the NSA has planted its feelers deep into the very foundation of the Internet. Allegedly, the US spy agency has even obtained access to Google’s data centers, though it’s not clear whether this happened with Google’s cooperation.
When it can’t legally force its way onto private systems, the NSA does its best to sneak in – case in point, a pilot program called Irritant Horn, that saw the NSA and its allies attempt to hijack the connection between a target smartphone and the Play Store (then called Android Market).”
