Using Google To Crack MD5 Passwords

stern writes "A security researcher at Cambridge was trying to figure out the password used by somebody who had hacked his Web site. He tried running a dictionary through the encryption hash function; no dice. Then he pasted the hacker's encrypted password into Google, and voila — there was his answer. Conclusion? Use no password that any other human being has ever used, or is ever likely to use, for any purpose. I think."

    That's not true. The user can generate a string with something like dd if=/dev/urandom bs=21 count=1|openssl base64 , store that string, and append it the the true password each time the log in. This has exactly the same results as the site correctly implementing salting. So what you are saying is the best defense is to use a crazy fucking password?

    And sure enough, if you read the comments to the blog, there is a site called http://md5.rednoize.com/ that reveals that the hash is "Anthony." So although Google helped, there appears to be resources online for it (if you don't have your own Rainbow Table mega database).

    Another reverse md5 hash lookup

    I have to agree with everyone else so far, pass the Salt.

    Crap. From their "about" page:

    Additionaly everytime when you enter a non-md5 hash string into the search field, the md5 result for that search strings gets stored in our database for future use. Thanks for warning me. I tested to see if my password was in there... it is now!!!
