Cr3dOv3r Credential reuse attack


Cr3dOv3r This tool checks your credentials on different websites and looks for if your email is in some data leak.

Your best friend in credential reuse attacks.

You give Cr3dOv3r an email then it does two simple useful jobs with it:

  • Search forreuse attack public leaks for the email and returns the result with the most useful details about the leak
  • Now you give it a password or a leaked password then it tries these credentials against some well-known websites (ex: Facebook, Twitter, Google…), tells if the login was successful and if there’s captcha somewhere blocking our way!

Some of the scenarios Cr3dOv3r can be used in it

  • Check if the targeted email is in any leaks and then use the leaked password to check it against the websites.
  • Check if the target credentials you found are reused on other websites/services.
  • Checking if the old password you got from the target/leaks is still used on any website.
