Mobile Application Penetration Testing
iOS and Android testing against OWASP MASVS — local data storage, certificate pinning, and the backend the app talks to once client-side controls are bypassed.
What it covers
A mobile app runs on a device you do not control, in the hands of someone who may be the attacker. Anything the app trusts the client to enforce can be bypassed with the right tools, so the real questions are what the app stores locally, what it leaks, and how the backend behaves once the client-side protections are gone. We test both halves against the OWASP Mobile Application Security Verification Standard.
What we test
Every engagement is scoped to your environment, but these are the areas a Mobile Application test engagement covers.
Local data storage
What the app writes to the device — tokens, PII, cached data — and whether it is protected.
Transport and pinning
TLS configuration and certificate pinning, and whether pinning can be bypassed to inspect traffic.
Authentication and session
How the app authenticates, stores tokens, and handles logout and biometric gating.
Reverse engineering
What a decompiled build reveals — hard-coded secrets, endpoints, and logic meant to stay hidden.
Backend API
The API behind the app, tested once client-side controls are removed — usually where the real risk sits.
How the engagement runs
The same defensible sequence every time.
Scoping and a fixed-price quote, reconnaissance and threat modeling, manual exploitation with same-day escalation of critical findings, a report your engineers and auditors can both use, and a free retest once fixes ship.
Mobile Application test, answered
Do you test both iOS and Android?
Yes, and they differ enough to warrant it — storage, keychain/keystore behavior and pinning are platform-specific. Scope can cover one or both.
Do you need the source or just the build?
A build (IPA or APK) is enough for a grey-box test. Source access enables deeper coverage and is used where higher assurance is required.
