Project Title: Android HIV: A Study of Repackaging Malware for Evading Machine-Learning Detection
#
Project Description
The proliferation of mobile devices and applications has resulted in a significant increase in malware targeting Android platforms. One of the most sophisticated techniques employed by cybercriminals is repackaging malware—an approach that modifies legitimate applications to include malicious payloads while retaining the application’s original functionality. This project, titled “Android HIV: A Study of Repackaging Malware for Evading Machine-Learning Detection,” aims to explore, analyze, and understand the mechanisms behind repackaging malware and develop strategies to enhance the detection capabilities of existing machine-learning models.
#
Objectives
1. Understanding Repackaging Techniques: The primary objective is to comprehensively understand the various techniques and tools used in the repackaging of Android applications for malicious purposes, including code obfuscation, resource manipulation, and the use of frameworks that facilitate this process.
2. Analyzing Malware Behavior: Analyze the behavior of repackaged malware in real-world scenarios to assess how these applications function, their potential impact on user devices, and their evasion tactics against machine-learning detection systems.
3. Machine Learning Model Evaluation: Evaluate the effectiveness of current machine learning models in detecting repackaged malware. This includes assessing false positives and false negatives in existing detection mechanisms.
4. Development of Robust Detection Mechanisms: Develop and propose enhancements to existing machine-learning models based on the findings from the previous objectives, thereby increasing their resilience against such evasion techniques.
5. Awareness and Education: Create awareness about the risks associated with downloading and installing repackaged applications and provide practical recommendations for users and developers on secure app deployment practices.
#
Methodology
1. Literature Review: Conduct a thorough review of existing literature on Android malware, particularly focusing on repackaging techniques and machine-learning detection methods.
2. Malware Collection and Analysis: Utilize automated tools to collect a substantial dataset of legitimate and repackaged Android applications. Conduct dynamic and static analysis to observe their behavior and modifications made during repackaging.
3. Model Training and Testing: Train various machine-learning algorithms (e.g., Decision Trees, Random Forests, Neural Networks) on the collected dataset. Implement experiments to test the efficacy of these models in detecting repackaged malware versus clean applications.
4. Enhanced Detection Framework: Based on the analysis results, develop an enhanced detection framework that integrates advanced techniques such as feature extraction, deep learning, and ensemble methods to improve detection rates.
5. Field Testing: Deploy the enhanced detection system in a controlled environment and conduct field tests to evaluate performance against emerging threats in real-world scenarios.
#
Expected Outcomes
1. Comprehensive Insights: A detailed report on the state of repackaging techniques in Android malware, including common patterns and trends observed.
2. Performance Metrics: Quantitative metrics on the performance of existing machine-learning models in detecting repackaged malware, which can be used to benchmark future models.
3. Enhanced Detection Framework: An open-source enhanced detection system that can be adopted by developers, researchers, and cybersecurity professionals to improve app security.
4. Public Awareness Material: Creation of educational materials, including guides and best practices, to inform Android users about the risks associated with malicious applications and the importance of app security.
5. Research Publications: Several research papers highlighting the findings of this study presented at relevant cybersecurity conferences and published in peer-reviewed journals.
