I used this weakness whilst working at British Telecom to legally break into some NT boxes on behalf of a FTSE 100 company whos system my team got asked to take over. They had had a bad break up with another supplier and had lost access. I used our Art directors MAC to break in - I did consider setting up a diy cracking farm using all our suns and running it over night but I suspect that the security department might not have approved.
