Re: Seen this before
I used to be site gardener on a big it/com's site,I got to know the in house it admin and his crew (useful for advice and freebies,their hardware skip was amazingly productive!!)
I was given written instructions that when on morning litter pick/site inspection to keep eyes open for Ian sticks etc and if found take them to only one guy in the it crew,it turned out their idiot co-employees kept "finding" Ian sticks etc in car parks etc and then just plugging into anything but their own machines to see what or who's data they had found,the it guy showed me the box that was half full of "compromised" sticks,some of which he reckoned did not contain the kind of malware etc that you would expect to pickt up from even the most "esoteric" porn site,he had a totally UN-connected bodge pc locked in a cupboard,which was used to check the sticks etc,he reckoned it must be one of the most badly infected machines he knew of,even though they used to flash a fresh image back to it every so often,and another box of sticks an bits the crew had removed from machines or folk and the state of some that folk had tried to plug in,usually having bin driven over a few times from the look of them !!
He reckoned that folk trying things like that had made them so much extra work that they ignored orders not to and blocked every Ian port in they could find in the entire building of three big floors !!2500 + machines,they reckoned to get away with it by pointing out how much money/time would be saved not having to firefight their co-workers idiot behaviours...
