Since the php script connects back to us, it is important that no firewall on our own system blocks it. Also if you are on a LAN behind a router then you need to configure port forwarding properly. That is the ip address and the port number it needs to connect to. There are many php reverse shell scripts out there and we are going to try a few of them in this post.
Step-by-Step: Setting Up a Reverse Shell with Netcat
{
- {
- First, start the listener on the attacking PC (Kali Linux) using the command below.
- A user (Client) establishes a connection to the remote server and requests services.
- If the system is running php then a php file can be uploaded to it which will give us a reverse shell.
- Once netcat receives the connection close the wget session as well.
- One kind of shell when the attacker’s machine is connected to the target machine again is called a reverse shell.
- Other configuration options include the ip address and the port.

If you are new to netcat then I suggest you read up my tutorial on netcat first. If the system is running php then a php file can be uploaded to it which will give us a reverse shell. There are many web based shell scripts but getting a terminal based shell is far more neater. First, start the listener on the attacking PC (Kali Linux) using the command below. Use the commands below depending on what is your Victim machine. The victim’s computer becomes the server while the attacker’s computer becomes the client.
A Brief Insight on Netcat
A user (Client) establishes a connection to the remote server and requests services. Python is one of the most popular scripting languages and comes preinstalled on most Linux distributions. In our case, we are using Windows as our Victim machine. To install Netcat on Windows, download the Netcat zip file from their official website and extract it on your system.
Netcat (if installed)
- {
- The victim’s computer becomes the server while the attacker’s computer becomes the client.
- There are many php reverse shell scripts out there and we are going to try a few of them in this post.
- If your ports are connectable from the outer internet then they are OK.
- First launched in 1995, Netcat is one of the most popular and lightweight command-line network security tools to date.
- Since the php script connects back to us, it is important that no firewall on our own system blocks it.
- This is because the script actually creates a separate process for the shell by forking.

From all the examples listed above of creating Reverse Shells, it’s the attacking machine (Kali Linux) that’s always on listening mode. Malicious software that comes with a backdoor mainly utilizes the Bind shells. First launched in 1995, Netcat is one of the most popular and lightweight command-line network security tools to date. One kind of shell when the attacker’s machine is connected to the target machine again is called a reverse shell. If your ports are connectable from the outer internet then they are OK. There is another php reverse shell script hosted at github.
