Securing iOS and Android Applications

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)

Comprehensive security requirements for mobile apps

OWASP Mobile Security Testing Guide (MSTG)

Industry-standard testing methodology for mobile applications

Methodology

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

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

Dynamic Testing

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

API and Backend Service Testing

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

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

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

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
