Our Mobile Application Testing services identify vulnerabilities in your iOS and Android applications, protecting user data and ensuring secure mobile experiences.
ReactiveZero offers specialized Mobile Application Security Testing for iOS and Android platforms. We identify vulnerabilities specific to mobile environments, including insecure data storage, weak authentication, and ansecure communication, helping you protect user data and ensure your mobile applications are resilient against attacks.
We work down through the application's layers, from the shipped build to the platform beneath it, the way a real attacker would.
We pull the shipped IPA and APK, decompile with jadx and Hopper, and map every screen, entry point and hardcoded secret.
On jailbroken and rooted devices we hook the app with Frida, bypass pinning and root detection, and abuse deep links and IPC.
We inspect the Keychain, Keystore, SQLite and preference files for tokens, credentials and personal data left readable on the device.
Proxying live traffic through Burp, we test transport security, then probe the backend APIs for broken authorisation, IDOR and weak sessions.
Finally we review OS-level controls — permissions, biometrics, backup and anti-tampering — and deliver a severity-rated report with prioritised fixes.
We test iOS apps against the OWASP Mobile Application Security Verification Standard (MASVS). Our consultants examine local data storage in the Keychain, files and databases, check certificate pinning and transport security, and probe authentication, session handling and biometric flows. We assess resistance to reverse engineering and runtime tampering on jailbroken devices, and inspect how the app handles sensitive data in memory, logs and backups. Every finding is reported with a proof-of-concept, its real impact and a concrete fix, followed by a retest once your developers have remediated.
We test Android apps to the OWASP MASVS, starting where attackers do: the APK itself. We review exported activities, services and content providers, over-broad permissions, insecure local storage and weak inter-process communication, then examine authentication, deep-link handling and transport security. Using dynamic analysis and reverse engineering on rooted devices, we assess obfuscation, root detection and runtime manipulation. You receive clear, reproducible findings ranked by exploitability, remediation guidance your developers can apply directly, and a free retest to confirm each issue is resolved.
A mobile app is only as secure as the API behind it, so we test both together. We map every backend endpoint the app calls — including hidden and undocumented ones — and probe them for broken object-level and function-level authorization (IDOR), authentication weaknesses, mass assignment, injection and business-logic abuse, guided by the OWASP API Security Top 10. Testing the API directly, not just through the app, uncovers issues the interface hides. Findings arrive with proofs-of-concept and prioritised fixes, and complement our wider web and API penetration testing.
