Tested like an attacker. Fixed like an engineer.

CREST-aligned iOS and Android penetration testing to OWASP MASVS/MASTG — covering the app binary, local storage, and the API backend it talks to.

Who this is for

Apps that carry sensitive data or payments

01

Banking & fintech apps

Mobile apps handling payments, banking, or sensitive customer data on iOS and Android.

Health & wellness apps

Apps storing PHI or operating in regulated healthcare contexts.

03

App store reviews

Apps needing security evidence to satisfy Apple or Google app store security review processes.

What is mobile app penetration testing?

The structured assessment of iOS and Android applications for exploitable security weaknesses.

It combines static analysis of the application binary, dynamic analysis of the running application (instrumented via Frida or similar), local storage and IPC review, and network traffic analysis against the API backend.

What mobile testing delivers

Coverage from the binary to the backend

  • OWASP Mobile Top 10 coverage across iOS and Android
  • Static and dynamic binary analysis
  • Local storage and keychain security review
  • Certificate pinning and TLS implementation review
  • API backend testing for the mobile-specific attack surface
  • Remediation guidance directly actionable by mobile devs
Modern mobile testing must cover both the on-device application and the API backend — testing one without the other misses most exploitable issues.
Why mobile testing matters

Devices attackers can root, instrument and decompile

Mobile apps now carry an outsized share of customer interaction and sensitive data flow. They handle authentication credentials, payment tokens, personal health information and direct API access to backend systems — all on devices that attackers can root, jailbreak, instrument and decompile.

Mobile weaknesses regularly enable serious incidents: stolen API tokens enabling account takeover, hardcoded secrets in shipped binaries, bypassable certificate pinning enabling MITM, weak local encryption exposing offline data. These issues are findable with proper testing and fixable with proper guidance.

  • API tokens stolen from insecure local storage
  • Hardcoded API keys and secrets in shipped binaries
  • Bypassed certificate pinning enabling MITM attacks
  • Sensitive data exposure in offline storage
  • Authentication bypass via local manipulation
  • Compliance failures across PCI DSS and HIPAA
Who needs mobile app testing?

Any app handling sensitive data, payments or authentication

Apple and Google app store review processes do not constitute security testing — they check policy compliance, not exploitable vulnerabilities. Dedicated mobile pentesting is the only meaningful pre-release security gate.

How we work

Our mobile testing methodology

CREST-aligned methodology aligned to OWASP MASVS and MASTG. Typical engagement: 5–8 days for a single platform, 10–15 days for combined iOS + Android testing with a shared backend.

  1. 01

    Scoping & build acquisition

    We agree the in-scope app (iOS, Android or both), test builds, test accounts and any out-of-scope features.

  2. 02

    Static binary analysis

    Decompilation and static analysis hunting for hardcoded secrets, weak cryptography, insecure dependencies and code-level flaws.

  3. 03

    Local storage review

    Keychain entries, shared preferences, SQLite databases, files and IPC mechanisms examined for sensitive data exposure.

  4. 04

    Runtime instrumentation

    Dynamic analysis with Frida, Objection or similar — bypassing client-side controls and examining crypto operations.

  5. 05

    Certificate pinning & TLS

    Testing pinning effectiveness, TLS configuration and the scenarios that bypass typical pinning implementations.

  6. 06

    API backend testing

    Testing the backend the app talks to — typically where most exploitable issues live.

  7. 07

    Reporting & developer walk-through

    Platform-specific reproduction steps, code-level remediation guidance and a live walk-through with your mobile team.

  8. 08

    Remediation retest

    Critical and high findings re-tested in a new build, with documented validation for compliance evidence.
