Outlook by default blocks .url attachments and not .htm – why?

Any dangerous URL that could be in .url file, could also easily be in a .htm file and could be launched using javascript automatically. I see the same risk with both attachments, but Microsoft treats it differently. Am I missing something here? How is a .htm file safer than .url?

What else could be in .url file that a hacker could not put in .htm file?

Maybe there is a known vulnerability with .url files which would cause contained data to be interpreted without user interaction. –  Oliver Salzburg Feb 28 '12 at 12:59

You can disable scripts and redirects through browser security settings if you desire to do so.

You'd need to disable .url file support completely for some protection against those.
