Token Reverser
Words list generator to crack security tokens.
Installation
$ git clone https://github.com/dariusztytko/token-reverser.git
Example use case
-
You are testing reset password function
-
Reset password token was sent to your email box (e.g. 582431d4c7b57cb4a3570041ffeb7e10)
-
You suppose, it is a md5 hash of the data you provided on registration
-
On registration you entered the following data:
- First name: Foo
- Last name: Bar
- Email: [email protected]
- Birth date: 1985-05-23
- Phone: 202-555-0185
- Address: 3634 Forest Drive
-
In addition, you have an access to the following extra data:
- Application user ID: 74824
- Date of the reset password HTTP request ("Date" response header): Tue, 10 Mar 2020 17:12:59 GMT
-
Use Token Reverser to generate words list from the known data:
python3 token-reverser.py --date "Tue, 10 Mar 2020 17:12:59 GMT" Foo Bar [email protected] 1985-05-23 202-555-0185 "3634 Forest Drive" 74824 > words -
Use hashcat to crack reset password token:
hashcat64.exe -m 0 582431d4c7b57cb4a3570041ffeb7e10 words hashcat (v5.1.0) starting... [...] 582431d4c7b57cb4a3570041ffeb7e10:[email protected]!1583860379 Session..........: hashcat Status...........: Cracked Hash.Type........: MD5 Hash.Target......: 582431d4c7b57cb4a3570041ffeb7e10 [...] -
Now you know that reset password tokens are generated as follows:
md5(user ID!first name!last name!email!current timestamp)
