Mobile App Security Testing

A mobile app is two attack surfaces in one: the binary running on a device you don’t control, and the backend API behind it. Attackers decompile the app, read hardcoded secrets, bypass certificate pinning and instrument the runtime to defeat client-side controls – then turn that understanding on the API. We test both halves as a single surface: static analysis of the binary, dynamic testing on jailbroken and rooted devices, and runtime manipulation with Frida and Objection to hook functions, bypass jailbreak/root detection and break SSL pinning.

Coverage is aligned with the OWASP Mobile Application Security Verification Standard (MASVS), with the MASTG used as a testing reference, producing a structured and repeatable report. We assess local storage, keychain and keystore use, cryptography, embedded secrets and API keys, transport security, platform use and resistance to tampering. Where included in scope, we also assess backend APIs for authorisation and authentication weaknesses such as BOLA, BFLA and authentication bypass. This can be combined with API Security Testing for end-to-end client and server coverage.
