Why It Matters

Client-side code is attacker-accessible code.

Unlike a server, a mobile app's binary lives on the attacker's own device — fully available for reverse engineering, tampering, and traffic interception. Hardcoded secrets, weak local storage, and unauthenticated APIs are routinely found sitting in production apps that passed a basic app-store review.

Where It's Useful

Any app that touches money, identity, or sensitive data.

Banking, lending, and fintech applications
Healthcare apps handling patient data
Consumer apps storing personal information
Enterprise and BYOD internal apps
Apps with in-app purchases or wallet features
Pre-launch app-store submission review
Our Methodology

We take the app apart the way a real attacker would.

Automated mobile scanners catch surface-level issues. We go further — manually reverse engineering the binary and testing the app's actual runtime behavior, not just its static code.

01

Static Analysis & Reverse Engineering

Decompiling and analyzing the application binary for hardcoded secrets, weak cryptography, and insecure logic.

02

Dynamic Runtime Analysis

Testing the app while it runs — instrumentation, tampering resistance, jailbreak/root detection bypass.

03

API & Backend Communication Testing

Intercepting and testing the traffic between app and server for authentication, authorization, and injection flaws.

04

Local Storage & Data-at-Rest Review

Checking exactly what sensitive data the app leaves behind on the device itself.

05

Business Logic & Abuse Testing

Testing app-specific workflows — payment flows, referral abuse, account recovery — for manipulation.

06

Reporting & Remediation Validation

Clear findings mapped to both the mobile client and backend, with a retest once fixes are in place.

Compliance & Standards Alignment

Aligned with mobile-specific and industry frameworks.
