mobile & apps security

Mobile devices are the front door to your services—protect every interaction. NotLAN’s Mobile Security tests Android and iOS apps end-to-end: from static code review and dynamic analysis to threat modeling and API/backend assessments. We examine data storage, secure communication, OS integrations, and third-party libraries. Combining automated scans with manual validation, we deliver prioritized findings and actionable fixes to harden your mobile ecosystem against real-world threats.

Our Mobile Security Services

Full-Scope Mobile Application Pentesting

• Dynamic runtime analysis of mobile apps in real device environments

• Reverse engineering and binary analysis (Android APK, iOS IPA)

• Authentication flows, token management, and session hijacking

• Insecure storage of credentials, keys, and sensitive data

• Code obfuscation bypass and anti-debugging evasion

API & Backend Testing

• Full testing of backend APIs consumed by the mobile app

• Abuse of API business flows, improper authorization, and privilege escalation

• Token reuse, IDORs, insecure session management, and replay attacks

• SSL pinning bypass to simulate attacker-in-the-middle scenarios

Client-Side Logic Abuse

• Manipulation of client-side logic to bypass restrictions

• Tampering with in-app purchases, feature flags, and subscription logic

• Abuse of hidden debug features and developer backdoors left in production

Data Leakage & Privacy Violations

• Identification of sensitive data stored insecurely on the device

• Insecure keychain, shared preferences, or SQLite database storage

• Analysis of data exfiltration through telemetry, analytics, or 3rd-party SDKs

Advanced Threat Simulation

• Malware drop scenarios, reverse shell payload delivery

• Rogue mobile app clone deployment

• Side-loaded app tampering and modification attacks

• Emulation of sophisticated nation-state-level attack vectors

Methodologies & Standards We Follow

Our mobile security assessments are grounded on established international standards:

     • OWASP Mobile Application Security Verification Standard (MASVS)

     • OWASP Mobile Top 10 (latest version)

     • OWASP ASVS (for APIs integrated into mobile apps)

     • PTES methodology applied to mobile attack surface

     • Custom adversarial testing scenarios based on client industry and threat profile

We adapt to regulated environments (e.g. finance, healthcare, critical infrastructure, Web3 wallets).

Why Work With NotLan?

✅ We attack mobile apps like real-world adversaries, not like compliance auditors.

✅ Full end-to-end testing: from the app code to backend APIs, authentication, and business logic.

✅ Advanced reverse engineering capabilities for both Android and iOS.

✅ Business logic flaw detection, beyond what automated tools can ever catch.

✅ Tailored remediation and advisory support for your development team.

Your mobile app is not just an app, it's part of your attack surface.
