The weakest point is the "human" webmaster!
They hack your site through any well known bug (adultcms/phpBB,whatever), place a shell (mostly .php / .gif / .jpg ) and search for your .htpass file or your sql details. Once your .htpass is stolen its easily decrypted with the right tools. (Generated user/pass combinations are also more hard to decrypt then normal combos like "user123 : 321user")
Bruteforcing was 1990...
So better keep your stuff updated and check for suspect files on your server.
