Once you have a reverse shell, you may want to consider dropping a SSH key so that you can return at a later time. This guide intends to serve as a quick tutorial on how to do this.
From the Compromised Remote Host:
Navigate to and/or create the following directory.
Change into it, and then run the following command.
ssh-keygen -f id_rsa
This should generate a private key along with a public key. You’ll want to create an “authorized_keys” file by running the following command.
cat id_rsa.pub > authorized_keys
Then you’ll want to take your private key to your local system by running the following command and copying the contents.
On Your Local System:
Create a new file by running the following command and pasting the contents of your clipboard.
Then make the appropriate file permissions changes.
chmod 600 id_rsa
That’s it! You should now be able to SSH in.
