First brought to my overtaxed attention by Bruce Schneier, comes this extraordinary story (actually two takes on the same story - ed.) of the first cyberattack against a network; via Bruce's monthly Crypt-O-Gram, of which, a gratis monthly subscription is waiting for you here... Read Paul Ducklin's piece at Sophos, and Tom Standage's tremendous prose on the same subject. You'll Be Quite Joyful You Did, I'll Wager!
