The Telegraph ran what appeared to be something of an exclusive this week, reporting that GCHQ are telling business to consider stripping smart phones from staff in order to avoid cyber attacks. Ben Riley-Smith bragged about documents “seen by The Telegraph” that warn firms that their employees are the weakest link in the security chain.

Where did the Telegraph get hold of these top secret documents? Surely they’re not this publicly available advice first published by GCHQ three years ago?
