Mobile Application Security

Mobile applications present a unique attack surface, with threats targeting user data, backend services, and device-level security. As mobile apps continue to evolve, so do the techniques adversaries use to exploit vulnerabilities in iOS and Android platforms.

SilentGrid’s Mobile Application Penetration Testing evaluates your apps from source code to runtime, identifying vulnerabilities that could lead to data leakage, unauthorised access, and compromised user privacy. Our comprehensive assessments ensure that both client-side and backend components are secure, safeguarding users and maintaining trust in your mobile ecosystem.

Testing Standards and Frameworks

SilentGrid’s mobile penetration testing aligns with industry standards to ensure comprehensive, recognised testing methodologies:

• OWASP Mobile Application Security Verification Standard (MASVS)
• OWASP Mobile Security Testing Guide (MSTG)

By adhering to these frameworks, SilentGrid ensures thorough testing that meets the highest security benchmarks.

Methodology

Our methodology evaluates vulnerabilities across application code, device interactions, and backend communications.

1. Static Analysis and Code Review

   • Decompiling and analysing app code to uncover hardcoded secrets, insecure configurations, and weak cryptographic implementations.
   • Identifying security flaws at the code level for iOS and Android.
   • Reverse engineering to understand app logic and data flows.

2. Dynamic Testing

   • Testing the application during runtime to identify vulnerabilities through reverse engineering, API manipulation, and runtime analysis.

3. API and Backend Service Testing

   • Assessing the security of APIs, server communications, and data flows.
   • Testing for unauthenticated access, weak authorisation and injection vulnerabilities.

4. Device and Local Data Storage

   • Evaluating how sensitive data is stored on the device.
   • Testing for data leakage, insecure local storage, and unprotected files or databases.

5. Network Communication and Encryption

   • Analysing network traffic to ensure encryption standards are followed.
   • Testing for man-in-the-middle (MITM) vulnerabilities and insecure transport protocols.

6. Platform-Specific Vulnerabilities

   • iOS Keychain and Android Keystore analysis.
   • Biometric authentication bypass testing.
   • App permissions and privacy controls review.
   • Deep linking and URL scheme testing.
   • WebView security assessment.
   • Push notification and background services security.

Deliverables

SilentGrid’s mobile assessments provide detailed insights to developers and product teams, ensuring vulnerabilities are addressed swiftly and securely.

You will receive:

• Comprehensive Vulnerability Report – Detailing vulnerabilities in the mobile app and backend services.
• Proof of Concept (PoC) – Demonstrations of exploitable weaknesses and attack paths.
• Remediation Guidance – Actionable steps for developers to resolve vulnerabilities across mobile platforms.
• Executive Summary – High-level overview highlighting risks and the overall security posture of the application.
• Consultation and Support – Post-assessment guidance to help development teams address issues effectively.

Why Mobile Security Matters

Mobile applications are increasingly targeted by adversaries due to their access to sensitive user data, device functionality, and backend services. A single vulnerability can compromise:

• User data privacy
• Corporate intellectual property
• Reputation and user trust

Proactive testing not only protects against these risks but also ensures compliance with privacy regulations and app store security requirements.
