I can help with this, I will run a MASVS-aligned audit (static + dynamic via MobSF, Frida, Objection, Burp), produce a CVSS-scored vulnerability report with remediation steps, and pair with your devs to close gaps. Audits map to OWASP MASVS (L1 baseline, L2 sensitive data) tested against MASTG. Common gaps: Android SharedPreferences without EncryptedSharedPreferences, missing certificate pinning on both, runtime tampering bypass via Frida/Objection. MobSF for baseline plus manual instrumentation. Questions: 1) Audit scope: black-box (no source) or grey-box (source + build access)? 2) MASVS level target: L1 (baseline), L2 (sensitive data), or full? 3) Stack: native (Swift/Kotlin), React Native, Flutter? Affects reverse-engineering surface. Send me a message and we can go over the details. Best regards, Faizan

Hey there I can take this on. Mobile security is one of those areas where small gaps can turn into real problems fast so it’s good you’re addressing it properly. I will start by performing a full security assessment of both iOS and Android builds focusing on common attack surfaces like API exposure local storage handling and authentication flows. I'll then run structured penetration testing to identify vulnerabilities including insecure data storage improper session handling and weak transport security while mapping everything back to real exploit scenarios. I will also work with your dev team to harden secure coding practices and ensure fixes are applied consistently across both platforms instead of patching issues in isolation. I will prepare a clear security report with prioritized risks remediation steps and practical recommendations that your team can actually implement without disrupting release cycles. Mobile App Development Penetration Testing Data Protection around 8 years experience working on application security audits and mobile security hardening for production apps. I will make sure the app is not only tested but structurally improved so user data stays protected under real world conditions.

Hi there. Securing the app starts with a focused iOS and Android assessment covering data storage, API traffic, authentication, permissions, and build configuration. Key risks are insecure local storage, weak certificate handling, exposed API keys, broken auth flows, unsafe logs, and missing jailbreak or root checks. I would first review the app builds and API traffic, then run static and dynamic tests and document each finding with fix steps. Do you have test builds for both iOS and Android ready? Are the backend APIs in scope for testing?
