Keep 'em guessing. Typical cold war mentality still exists and will never change.
There's not a chance in hell that any hacker is going to find a single file with anything more than weather balloons or swamp gas.
That's my 2 cents,.
That is the thing, it was no super security system, it was a fresh install of Windows Terminal Services, and some numpty forgot to Password the Admin account.
Google "XP Password Admin Account". By default XP has no Admin pasword. All McKinnon had to do was walk through the door. It was not locked. McKinnon thought he was some sort of computer super hacker and left messages of Bravado on peoples screens. It would not have taken much to catch him. The whole thing is so stupid, that in a way, it is funny. He was not clever, he got lucky and thought he was clever.
And you can download the Terminal Services access client for free from Microsoft. Howzat. They give them the system, and the public the keys! I wonder how Bill Gates managed to keep his nose clean through all this.
