Security has been a commonly misunderstood problem as early as that unfortunate incident at Troy, an ancient city in what is now western Turkey. The Trojans thought their walls were impenetrable, and they felt secure, but like modern social platforms, they underestimated the social-engineering abilities of their adversaries. The Greeks withdrew from battle and left a tall wooden horse as a gift. The Trojans loved the gesture and took the horse inside their walls to cherish it. At midnight, the Greek soldiers hidden in the hollow horse got out and opened the gates, letting the Greek armies in and causing the downfall of the city. At least, that’s what we know from the postmortem blog posts of Homeros, possibly the first instance of irresponsible disclosure in history.
