12/31/2022 0 Comments Netcat reverse shell![]() ![]() The attacker’s workstation would listen on a port that most firewalls allow, such as port 80 (the web server port) or 443.Īs we previously stated, one of the benefits of reverse shells is that most firewalls do not block outbound traffic, and in most circumstances, a firewall cannot distinguish between a user surfing the web and a backdoor communicating back to the attacker’s machine:īut there is a caveat. Rather than acting as a server and listening for the client’s commands, the victim machine takes on the role of a client and connects back to the penetration tester’s system. As you can imagine, this thing is used after the exploitation of a vulnerability (for example, RCE) to fix it on the attacked machine and conveniently interact with it.Ī reverse shell is a typical way to get around firewalls. That is, you execute a command on some machine, after which this machine connects to another and provides access along with this connection. ![]() Reverse - denotes the type of shell, the thing is that the meaning of such a shell is to connect (connect) with a remote host and constantly interact with it. What is reverse shell? #Īs the name suggests, this is some kind of shell (some kind of access to certain resources), like SSH to access a remote machine, or a regular console in Linux, which is also a kind of shell. ![]() Once we are able to execute code remotely, for example, using a known RCE-vulnerability it is important to continue further with more advanced post-exploitation phases. In this post we will find out what a reverse shell is and look at practical implementation examples using netcat. ![]()
