Mobile-first attack surface

Mobile Application Security Assessment

We test iOS and Android applications from device to backend to uncover weaknesses in data, APIs, communications, and client-side controls.

Why this matters for iGaming

The Device You Don't Control Now Handles the Money

Deposits, gameplay, identity checks, and withdrawals now happen on devices outside your control. An attacker with the app can decompile it, inspect stored data, and study its communication with your backend without ever touching your infrastructure.

That creates specific risks for iGaming. Client-side controls such as geolocation, jurisdiction and verification can be bypassed, while cloned or modified apps can expose players to fraud, credential theft and manipulated transactions.

What we assess

Tested the Way an Attacker Actually Gets In.

A mobile assessment moves from the iGaming app on the device outward to the systems it talks to, so what comes back reflects a real attack path, not a checklist of unrelated findings.

Reverse engineering resistance

What decompiling the binary hands an attacker, and whether obfuscation and anti-tampering hold up under pressure.

On-device storage

Session tokens, credentials, player data, payment and KYC information cached in storage, caches, logs or backups, and whether any of it is recoverable from a lost, shared or compromised device.

Network communication

TLS configuration and certificate pinning, and whether the app-to-backend channel resists interception and manipulation.

Client-side controls

Geolocation and jurisdiction enforcement, root and jailbreak detection, tamper detection and biometric gating, and what it takes to bypass each one.

Platform integration

Deep links, WebViews, inter-process communication, and insecure use of OS-level features

Backend and API interaction

How the app authenticates and exchanges data with server-side systems, and what that exchange exposes.

Wallet and payment flows

For operators supporting crypto deposits or payouts, wallet-connection and transaction-signing flows are assessed as a direct route into player funds.

In practice

Five Questions Worth Answering.

Every engagement is built around a specific, business-critical question rather than an open-ended hunt for bugs. Scenarios run under agreed rules of engagement, with each one designed to return a definitive yes or no.

/01

Can location and jurisdiction checks be bypassed?

If enforcement lives on the client, testing shows whether a player, or a fraud operation, can make the app believe they're somewhere they aren't. The scenario with the most direct licensing consequences.

/02

What's recoverable from a lost or compromised device?

Researchers work through local storage, caches, logs, and backups for session tokens, credentials, and player data left exposed at rest.

/03

Can the app-to-backend channel be intercepted?

Testing shows whether weak or absent certificate pinning lets an attacker sit between the app and your servers, read requests, and probe what's behind them.

/04

Can root and tamper detection be defeated?

Researchers work to run the app in an instrumented environment and manipulate its behavior at runtime, past the protections meant to stop exactly that.

/05

Can the app be cloned and put back into the world?

This scenario tests how easily the app can be repackaged and redistributed, the basis of fake-casino-app fraud and credential phishing.

Our methodology

How the Work Actually Gets Done.

A methodology built for teams that need to trust the process, not just the report. Each element below is designed to withstand technical scrutiny from CTOs, CISOs, and engineering leads. Rules of engagement, scope boundaries, prohibited actions, stop conditions, and handling of any sensitive data encountered are agreed and locked in advance, so testing is performed on agreed builds and test accounts, never live player accounts or funds.

Static analysis and reverse engineering

The app binary is decompiled and inspected for hardcoded secrets, weak cryptography, and insecure storage patterns.

Dynamic and runtime analysis

Instrumentation and runtime manipulation test whether client-side controls and tamper resistance hold up on a hostile device.

Network analysis

Interception testing against TLS and certificate pinning, alongside inspection of the app's API interactions for exposure and manipulation.

Senior researchers, every engagement

Every engagement is led start to finish by experienced offensive researchers, with consistent ownership across the full duration of the work.

AI extends reach, judgment stays human

AI accelerates reverse engineering and surfaces data-flow patterns across complex mobile architectures, while judgment and decision-making stay with the engineer at every step.

Results Your Team Can Benchmark

Methodology maps to the OWASP Mobile Application Security Verification Standard (MASVS) and Mobile Application Security Testing Guide (MASTG), keeping results legible to your team and comparable engagement over engagement.

Scope

The Full Path, From Device to Backend

Each layer of coverage feeds into a single picture of exposure across the app, scoped with your team before testing starts.

What the engagement covers

iOS application, native and/or React Native, including WebView layers
Android application, native and/or React Native, including WebView layers
On-device surface: local storage, keychain/keystore, caches, logs and backups
App-to-backend channel: transport security, pinning, API authentication
Client-side controls: geolocation, root/jailbreak, tamper and biometric gating
Distribution integrity: resistance to reverse engineering, repackaging and cloning
Wallet and payment integration, where crypto deposits or payouts are in scope

WHAT YOU RECEIVE

Findings with severity classification and business impact
Reproduction steps and evidence for your engineers to verify each finding
Remediation guidance covering both app-side and backend fixes
Executive summary for decision-makers
Retesting, included in the engagement

Why GameGuardz

The Sharper Questions Are the Licensed Ones

Standard mobile testing focuses on the application itself. We also test the controls behind it, from jurisdiction and account restrictions to wallet connections and other logic specific to iGaming operations.
That means testing whether those controls still hold when the app is modified, manipulated or used in unintended ways, connecting technical weaknesses to the operational risks they can create.

Faq

QUESTIONS WE GET ASKED

Yes. Coverage includes native iOS and Android builds and React Native implementations, including their WebView layers.

Yes, when jurisdiction or location enforcement runs on the client, testing it is a standard part of the assessment, not an add-on.

A web app runs on infrastructure you control. A mobile app runs on a device you don't, so the assessment adds reverse engineering, on-device storage and client-side control bypass on top of the backend and API testing shared with a web engagement.

The built app is enough. Source access can speed up parts of the review where it's available, but it isn't required.

Methodology maps to the OWASP MASVS and MASTG, so results stay legible to your engineering team and comparable across engagements.

Yes, when an operator supports crypto deposits or payouts, wallet-connection and transaction-signing flows are tested as direct paths to player funds.

Assess the iGaming app on the attacker's terms.

A short scoping call is enough to confirm platforms, builds, and the client-side controls most worth pressure-testing.
