In Australia, our cyber security laws are very strong. There is no way I'd attempt to access services on random IP's to test if they use no password with common usernames for those services. Any semi compotent prosecutor could argue I accessed a computer without permission and they'd be 100% correct. The only way I can see myself accessing a computer and not breaking a law is through a genuine mistake i.e. mistyping an IP/url and somehow having the right username + password. I prefer to stay 100% on the legal side. The only way I'll touch a computer is with a signed document from the owner giving me permission and with clear instruction on what I can and cannot do.
