Cr3dOv3r – Best friend in credential reuse attacks

What is Cr3dOv3r?

Cr3dOv3r simply you give it an email then it does two simple jobs (but useful) :
– Search for public leaks for the email and if there’s any, it returns with all available details about the leak (Using hacked-emails site API and now haveibeenpwned API too).
– Now you give it this email’s old or leaked password then it checks this credentials against 13 websites of well-known websites (ex: facebook, twitter, google…) then it tells you if login successful in any website!

Some of the scenarios Cr3dOv3r can be used in it

  • Searching for a targeted-email for leaks and then use the leaked password to check it against the websites.
  • Testing an email and an old password you found on the websites.
  • You got a target email and password and want to check if he uses the same password on other websites.


To make the tool work at its best you must have :
– Python 3.x or 2.x (preferred 3).
– Linux or Windows system.
– Worked on some machines with MacOS and python3 (Thanks for @MansoorMajeed and needs to others to confirm that)
– The requirements mentioned in the next few lines.
