Re: Logic bombs are unprofessional
Some companies create their own logic bombs by following procedure.
I seem to recall a large beverage company going offline after discovering that their DNS name was being paid on an individuals expenses credit card. Person leaves or is "downsized" then no one pays the bill then watch the entire organisation go dark until someone can work out how to deal with it.
I don't advocate non-process initiated logic bombs though. As said elsewhere, that can indeed get you into a lot of trouble.
