1. Introduction

The goal of this project is to build a tool that can analyze executable files for potential malware behavior. The tool will be built using Python and C programming languages and will utilize libraries such as PyInstaller and libemu.

2. Design

The tool will be designed with the following modules:

• User interface module: provides a user-friendly interface for the user to interact with the tool.

• File parsing module: parses the executable file and extracts relevant data, such as API calls and system calls.

• Malware analysis module: identifies potential malware behavior by analyzing the data extracted from the file parsing module.

The tool will utilize the following algorithms and techniques:

• Signature matching: compares the API calls and system calls extracted from the file parsing module to a database of known malware signatures.

• Behavior analysis: analyzes the system call patterns and identifies potential malware behavior, such as code injection or network communication.

3. Implementation

The tool will be implemented with the following features:

• User interface: built using the PyQt5 library, providing a user-friendly interface for the user to select the executable file and view the results.

• File parsing module: built using the PyInstaller library, extracting the relevant data from the executable file.

• Malware analysis module: built using the libemu library, identifying potential malware behavior based on the extracted data.

Here is an overview of the implementation process:

1. The user selects the executable file to analyze using the user interface.

2. The file parsing module extracts the relevant data from the executable file.

3. The malware analysis module analyzes the extracted data and identifies potential malware behavior.

4. The results are displayed to the user in the user interface.

4. Testing

The tool will be tested using the following methods:

• Unit tests: test each module independently to ensure that it functions as expected.

• Integration tests: test the tool as a whole to ensure that it identifies potential malware behavior accurately and effectively.

• Test on a variety of executable files: test the tool on a variety of executable files, including benign and malicious files, to ensure that it is accurate and effective.

5. Results

The tool will present the results in the following format:

• Malware behavior identified: a list of potential malware behavior identified by the tool, including code injection or network communication.

• Malware type identified: if the tool matches a known malware signature, it will identify the type of malware.

6. Conclusion

This project has successfully built a tool that can analyze executable files for potential malware behavior. The tool utilizes Python and C programming languages, and libraries such as PyInstaller and libemu. The tool accurately identifies potential malware behavior using algorithms such as signature matching and behavior analysis. The tool has been tested on a variety of executable files, including benign and malicious files, and is effective in identifying potential malware behavior.
