Mobile Application Penetration Testing

Your mobile app is running on a device you don't control, handed to users you can't fully trust. We test it as if it's already in the hands of someone trying to take it apart.

Penetration Testing[ MOB ]

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 applies

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
  • Apps embedding an on-device or hosted AI model
  • 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.

  1. 01

    Static Analysis & Reverse Engineering

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

  2. 02

    Dynamic Runtime Analysis

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

  3. 03

    API & Backend Communication Testing

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

  4. 04

    Local Storage & Data-at-Rest Review

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

  5. 05

    Business Logic & Abuse Testing

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

  6. 06

    Reporting & Remediation Validation

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

Standards & compliance

Aligned with mobile-specific and industry frameworks.

  • OWASP MASVS
  • OWASP Mobile Top 10
  • PCI-DSS (payment apps)
  • GDPR / Data Privacy
  • ISO 27001
