Penetration Testing
Your app is installed on millions of devices. An attacker who reverse-engineers it and finds a hardcoded API key or a broken session token has everything they need. We find these weaknesses before your app hits the store review.
About This Service
In-depth security assessment of your iOS and Android applications — testing the app binary, data storage, network communication, and backend APIs for real-world exploitable vulnerabilities.
Mobile apps process sensitive data, authenticate users, and communicate with backend APIs — all of which represent attack surface that is rarely tested with the same rigour applied to web applications. Vulnerabilities in mobile apps often expose the same backend systems your web app testing covers.
OWASP MASVS, OWASP MSTG
Typical Timeline: 5–10 days depending on app complexity
Report: Executive summary + full technical findings
Retest: Complimentary, included in every engagement
NDA: Signed before any technical discussion
Deliverables
Risk overview for product and security leadership
All findings mapped to OWASP MASVS categories with screenshots, proof-of-concept, and CVSS scores
Documented results of binary analysis including hardcoded secrets and insecure configurations
Runtime testing results including traffic interception, storage analysis, and authentication testing
Platform-specific fix guidance for iOS and Android developers
Confirms critical and high findings resolved after remediation
Scope
Insecure data storage — cleartext credentials, PII in logs, unprotected files
Insecure authentication and session management
Broken cryptography and weak key management
Insecure network communication — cleartext traffic, certificate pinning bypass
Client-side injection vulnerabilities
Hardcoded secrets and API keys in the app binary
Reverse engineering and tampering resistance
Backend API security for mobile endpoints
Third-party SDK and library risks
Android-specific: exported components, intent vulnerabilities
iOS-specific: keychain misuse, ATS configuration, Plist exposure
Process
Every engagement follows a defined, transparent process — no surprises, no hidden scope changes, and no invoice for work you did not agree to.
Obtain app builds (APK/IPA), test accounts, and backend API documentation.
Reverse engineer the app binary to find hardcoded secrets, insecure configurations, and code-level issues.
Run the application in a test environment and intercept traffic, monitor file system activity, and test runtime behaviour.
Assess all backend API communication for security weaknesses.
OWASP MASVS/MSTG-mapped findings with proof-of-concept and remediation guidance.
Verify critical findings have been resolved.
Why Us
Automated tools find known signatures. Our certified consultants find the chained attack paths, logic flaws, and context-specific vulnerabilities that no scanner will surface. Every finding we report is manually verified — zero false positives.
Every finding includes a proof-of-concept, a CVSS risk score, the affected system or endpoint, and step-by-step remediation guidance written for the team that has to fix it. Your developers and your board both get a report they can use.
We sign a formal NDA before any technical discussion begins. Your vulnerabilities, your architecture, and your engagement findings are treated with the same confidentiality as attorney-client communications. We have never disclosed client information.
Every engagement includes a complimentary retest once your team has addressed the findings. We verify that the vulnerabilities are genuinely closed — not surface-patched — and issue a formal retest certificate you can share with clients and auditors.
Many firms offer mobile testing that only covers network traffic. We conduct full static analysis of the app binary — decompiling and reverse engineering to uncover secrets, logic, and misconfigurations baked into the code itself — combined with live dynamic testing on real devices.

FAQ
Yes. We test both platforms. iOS testing uses real devices and the Frida framework for dynamic analysis. Android testing includes APK analysis, root/emulator-based testing, and traffic interception.
No. We conduct both black-box (binary only) and grey-box (with partial source) engagements depending on your preference. Source code access improves depth of finding.
We follow the OWASP Mobile Security Testing Guide (MSTG) and Mobile Application Security Verification Standard (MASVS).
Yes. Certificate pinning bypass is part of our standard mobile testing methodology for dynamic analysis and network traffic interception.
