Re: Website "Scanner"

What does legality have to do with it?  Is it technically possible or 
not?  Are there tools freely available to do it or not?  Plenty of 
things are illegal to do with security tools if you are not the owner of 
the system or authorized by the owner of the system.  But these same  
tools can be used by penetration testers to demonstrate why a site owner 
shouldn't rely on obscurity of filenames or paths.

I am also not convinced that accessing a file that is not explicitly 
linked from other published files on a web server is illegal in the 
first place.  They have been cases of people guessing URLs for upcoming 
corporate press releases, finding prepublished information and sending 
it to reporters.  I have never heard of charges being filed in any of 
these cases.

Cheers,

Chris
