- Research, design, and improve anti-cheat systems for Android games.
- Perform static and dynamic analysis using industry-standard reverse engineering tools.
- Investigate game modifications, memory hacks, injection techniques, and runtime manipulation.
- Develop detection mechanisms for rooted devices, debuggers, emulators, hooking frameworks, and code tampering.
- Perform security assessments of backend APIs, authorization mechanisms, and business logic.
- Analyze network traffic to identify protocol vulnerabilities, replay attacks, packet manipulation, and unauthorized communication.
- Build internal automation tools for security analysis, reverse engineering, and vulnerability detection.
- Collaborate with development teams to implement secure coding practices and security-by-design principles.
- Document vulnerabilities, proof-of-concepts, mitigation strategies, and security recommendations.
- Stay up to date with the latest game hacking techniques, Android security research, and anti-cheat technologies.
