Offensive Security

Mobile Application Testing

Android and iOS application testing against the OWASP Mobile Application Security Verification Standard — insecure storage, transport, reverse engineering and platform misuse.

Request this test → See our methodology

Overview

Security that travels with the device.

Mobile apps run on devices you don’t control, which changes the threat model entirely. Data left on the device, weak transport security and apps that can be reverse-engineered or tampered with all create real risk.

We test both the client and its server-side APIs against the OWASP MASVS, using static and dynamic analysis on real devices to surface issues across storage, communication, authentication and platform interaction.

What we test

Focus areas of the assessment.

The core areas we examine in a mobile application testing engagement.

Insecure data storage

Sensitive data cached, logged or stored unprotected on the device.

Insecure communication

Transport security, certificate validation and pinning weaknesses.

Authentication & session handling

Credential storage, token handling and session lifecycle on mobile.

Reverse engineering & tampering

Resistance to decompilation, code tampering and runtime manipulation.

Platform interaction & IPC

Misuse of platform features, exported components and inter-process channels.

Cryptography usage

Weak or misapplied cryptographic controls protecting app data.

Who needs this

Regulatory drivers

Why this is required

Mobile apps handle credentials, payments and personal data on devices outside your control, which places them squarely within payment and privacy obligations; testing to the OWASP MASVS is the recognised benchmark.

PCI DSS / PCI MPoC

Mobile apps that capture or transmit payment data are subject to payment-security and testing requirements.

RBI / NPCI

Mobile banking and payment apps carry specific security expectations across the regulated payments ecosystem.

DPDPA & GDPR

Require safeguards for personal data stored or processed on mobile devices, including secure storage and transmission.

OWASP MASVS

The recognised standard against which mobile application security is verified.

How we work

A disciplined testing methodology.

A repeatable, standards-based process that balances depth with operational safety.

Scoping & build intake

Receiving the iOS/Android build and agreeing platforms and scope.

Static analysis

Inspecting the binary, local storage, secrets and insecure configurations.

Dynamic & runtime testing

Runtime testing for tampering, hooking and insecure behaviour.

Backend & API testing

Assessing the APIs and services the app communicates with.

Exploitation & data-leakage validation

Confirming data leakage and exploitable issues with evidence.

Reporting & retest

Findings mapped to the OWASP MASVS, with remediation and a retest.

FAQ

Common questions

Do you test the backend APIs too?

Yes. A mobile assessment includes the server-side APIs the app depends on, since many of the most serious issues live behind the app rather than in it.

Do you need source code?

Not required — we can test the compiled app. Source access (white-box) deepens coverage and is recommended where available.

Which devices do you test on?

We test on representative real devices and operating-system versions for each platform, rather than emulators alone, so results reflect real-world behaviour. Where your user base concentrates on particular devices or OS versions, we align the test set to match. Both Android and iOS builds are covered where applicable.
