MOBILE APP PENETRATION TESTING

Ship the app. Don’t ship the secrets.

We test the build on real devices, then the backend it talks to. Insecure storage, weak crypto and missing certificate pinning.

The app on the store is a copy in every attacker’s hands.

COVERAGE

What a mobile app pentest covers

Every item below is tested by hand, not just scanned. Nothing here is a checkbox exercise.

Tested againstOWASP MASVS / MASTG
  • Insecure data storage
  • Hardcoded secrets & keys
  • Weak or broken cryptography
  • Insecure transport & certificate pinning
  • Reverse engineering & tampering
  • Authentication & session on device
  • Inter-process & deep-link abuse
  • Backend API (shared with API testing)

WHY IT MATTERS

What this stops before it happens.

These are the outcomes we are actually testing for. Not theory, these are the paths we take on real engagements.

  1. Secret extraction

    Attackers decompile the build and pull hardcoded keys and secrets.

  2. Client-side auth bypass

    Controls enforced only on the device are trivially bypassed.

  3. Traffic interception

    Missing certificate pinning lets attackers read and modify traffic.

HOW IT RUNS

Six phases, no surprises.

  1. 01ScopeTargets, access and rules of engagement, agreed in writing.
  2. 02ReconMap the real attack surface the way an attacker would.
  3. 03ExploitManual, hands-on testing. Flaws chained, impact proven.
  4. 04ReportCVSS, proof, business impact and a concrete fix per finding.
  5. 05RemediateWe support your engineers through every fix.
  6. 06RetestEvery fixed finding re-tested, at no extra cost.

FAQ

Questions we get about mobile app pentest

What do you need to test a mobile app?

The app builds (IPA/APK), test accounts, and any backend documentation. Backend API testing is often bundled in.

Do you test on real devices?

Yes, including jailbroken/rooted devices to assess storage, tampering and pinning under realistic attacker conditions.

Does this cover the backend too?

The mobile backend API is frequently the real attack surface. We can include it, aligned with our API testing.

What standards do you follow?

The OWASP Mobile Application Security Verification Standard (MASVS) and testing guide (MASTG).

What happens after the report?

You get a prioritized remediation roadmap and a free re-test of fixed findings.
