Your remote shell will need a listening netcat instance in order to connect back, a simple way to do this is using a cloud instance / VPS - Linode is a good choice as they give you a direct public IP so there is no NAT issues to worry about or debug, you can use this link to get a $100 Linode voucher. If you want other ways (and this way is included) read the canonical ropnop article.

During penetration testing if you’re lucky enough to find a remote command execution vulnerability, you’ll more often than not want to connect back to your attacking machine to leverage an interactive shell.īelow are a collection of reverse shells that use commonly installed programming languages, or commonly installed binaries (nc, telnet, bash, etc).
