I follow a tutorial about the race condition exploit.I made a copy of my /etc/shadow file.And then replace all the contain by one lineroot::1:99999:::::However. My old password doesn't work anymore when I'm trying to use the command su. :/I kept my old shadow file but try to restore it. However I can't because I'm not su and can't become su anymore.Does anyone know if it's possible to deduce which is the new su's password only with the line I provided above ?I'm currently on Linux Mint 18.
Recover su password after modifying /etc/shadow
linux;login;root;su;system recovery
