I want my Flutter app thoroughly tested against the OWASP Mobile Security Testing Guide so I can certify it has zero security bugs. For this engagement I’m concentrating specifically on Authentication—everything from credential handling to session management. Key points • Scope: full review of authentication workflows in the current production build of the Flutter app (Android + iOS). • Standard: follow the official OWASP methodology; no additional in-house policies need to be considered. • Deliverables: – Executive summary highlighting discovered issues (ideally none) and overall risk posture. – Detailed technical report with proof-of-concept steps, affected code paths, and recommended fixes for every finding. – Retest results that confirm the fixes and document the final “0 bugs” status. I will supply the signed APK/IPA, dummy credentials, and any backend endpoints you need. Please indicate which tools you plan to use (e.g., Burp Suite, MobSF, Frida) and estimate the turnaround time for the initial report and the follow-up retest.
