Emilien Girault is a seasoned software security engineer with 14 years of hands-on experience in reverse engineering, vulnerability research and penetration testing across government, enterprise and consumer platforms. Currently at Apple, he focuses on security assessments of software and hardware protections, including DRM technologies, after earlier roles at ANSSI and boutique security firms where he audited critical infrastructures and developed exploit techniques for PLCs, firmwares and proprietary protocols. He has a strong build-and-break mindset, demonstrated by developing anti-reverse-engineering kernel protections, pentest automation tools and PoC projects such as an unofficial Google Play Python API that parsed Android .proto files to optimize bulk app queries and reviews retrieval. Comfortable with low-level reverse engineering and practical security engineering, he also writes tooling and research that bridges audits and automation. Based in France, Emilien pairs deep technical craft with real-world red-team experience and a subtle focus on making protections resilient against determined, hardware- and software-focused attacks.

Contributions summary:Emilien primarily focused on reverse engineering and analyzing the Google Play API. Their contributions included developing a Python script using the Androguard library to extract and analyze `.proto` files from Android APKs, likely to understand the API's data structures. They extended the API functionality by implementing a method for fetching multiple app details in a single request, optimizing API calls. Additionally, the user added features for retrieving app reviews and incorporated localization support.
