Training Course on App Store Forensics and Malicious App Analysis

Training Course on App Store Forensics and Malicious App Analysis

Introduction

This specialized training course is meticulously designed for digital forensic investigators, cybersecurity analysts, mobile security researchers, and incident response teams tasked with navigating the complex landscape of app store ecosystems and combating malicious mobile applications. With billions of apps available on platforms like Google Play Store and Apple App Store, and a growing threat of repackaged malware, adware, banking Trojans, and sophisticated spyware, the ability to effectively analyze these applications for forensic artifacts and malicious intent is paramount. Training Course on App Store Forensics and Malicious App Analysis provides the advanced knowledge and hands-on techniques required to extract, reverse engineer, and analyze digital evidence from mobile devices, cloud platforms, and application binaries, crucial for uncovering cybercrime, intellectual property theft, data breaches, and other security incidents.

The curriculum delves into the inner workings of both Android (APK) and iOS (IPA) application packages, exploring their file structures, code obfuscation techniques, and common persistence mechanisms. Through extensive practical labs, dynamic and static malware analysis, sandboxing, and mobile forensics tool utilization, participants will gain proficiency in identifying relevant data sources, extracting user activity logs, sensitive data (e.g., credentials, contacts), network communications, and obfuscated malicious code. The course also critically addresses the significant privacy implications of app data collection and the complex legal frameworks (including Kenya's Data Protection Act 2019) governing app store data acquisition and analysis, ensuring that all investigative practices are forensically sound, legally admissible, and ethically compliant, empowering investigators to combat the evolving threat of malicious mobile applications.
