Have Apple OS X users taken the blue pill?

As any fan of the The Matrix trilogy of films will tell you, the Keymaker is a character in The Matrix Reloaded who has the keys to provide Neo access to the system mainframe and by so doing hopefully save Zion from the ongoing sentinel attack. In the movie, the Keymaker was a little old Chinese man who held the keys to every door, every escape route, everything. In Apple OS X the equivalent is the Gatekeeper, a key technology which prevents malware from running on machines using that operating system. It does this by effectively locking the doors to applications which are not legit and digitally signed to prove it. Or at least it should. Now a researcher reckons the Apple Gatekeeper isn't all that. Indeed, Patrick Wardle who is the Director of Research at Security-as-a-Service specialists Synack, says that it is "trivial for any attacker to bypass the security tools on Macs."
