Mobile App Security Penetration Test

I need a seasoned penetration tester to probe the security of my production-ready mobile app on both Android and iOS. The first priority is the app itself; backend and API endpoints can follow only if weaknesses in the binaries point that way.

My single, overriding goal is to find out whether an attacker could access or steal sensitive user data—specifically photos, messages, location details, and contact information that the app stores or transmits. I expect you to approach the assessment exactly as a real-world adversary would, using recognised methodologies such as OWASP Mobile Top 10, dynamic analysis, and code review where possible.

Deliverables
• A clear, reproducible vulnerability report for each issue, including risk rating and affected OS/version
• Proof-of-concept evidence (screens, logs, or video) showing how data could be compromised
• Actionable remediation steps ranked by priority

I’m happy to provide test accounts, current builds, and any required certificates once we agree on scope and timeline.
