Mobile App Penetration Testing
Mobile application penetration testing is a manual, expert-led assessment of your Android and iOS apps — and the backend APIs behind them — that finds and safely exploits vulnerabilities before attackers do. Aligned to the OWASP MASVS, we test insecure storage, weak cryptography, hardcoded secrets, insecure communications, authentication and session flaws, and reverse-engineering resistance, then give you a risk-rated report, remediation guidance, and a free retest.
The OWASP Mobile Top 10 — and beyond
The mobile-specific flaws that most often expose users and data.
Insecure data storage
Sensitive data left unprotected on the device — plaintext in SQLite, shared preferences, plists, logs, caches, or backups that an attacker with device access can read.
Weak cryptography
Hardcoded keys, weak or home-grown algorithms, and poor key management that let an attacker decrypt stored data or forge trusted values.
Hardcoded secrets
API keys, credentials, and tokens baked into the app binary that fall out under reverse engineering and hand attackers direct access to your backend.
Insecure communications
Missing TLS, disabled certificate validation, and no certificate pinning — allowing man-in-the-middle interception of traffic between the app and your servers.
Authentication & session flaws
Broken login, insecure token handling, weak biometric or PIN gating, and session management flaws that let attackers become other users.
Reverse engineering & tampering
Absent root/jailbreak detection, no anti-tampering, and easily patched binaries that let an attacker modify logic, bypass controls, or clone the app.
A proven, MASVS-aligned process
Scope
We agree the platforms (Android, iOS), builds, test accounts, and rules of engagement in writing — so testing is safe, authorized, and focused on what matters.
Static analysis
We decompile and inspect the binary and resources for hardcoded secrets, insecure storage, weak crypto, and dangerous configuration before it ever runs.
Dynamic analysis
Aligned to the OWASP MASVS/MASTG, we run the app on real and rooted/jailbroken devices, hook runtime behavior, and inspect data at rest and in transit.
Backend & API testing
The mobile app is only half the story. We test the APIs it talks to for broken authorization, injection, and data exposure — where real breaches often happen.
Report
A clear report with an executive summary, risk-rated findings, evidence, and step-by-step remediation your engineers can act on.
Retest
After you fix the findings, we retest and confirm closure — so you can show auditors, app stores, and customers the issues are resolved.

Deliverables that drive action
Professional report
Every finding documented with proof-of-concept evidence, affected components, and reproduction steps — plus a plain-language executive summary.
Remediation guidance
Actionable, developer-ready fixes for each finding across the app and its backend — not just a list of problems, but how to close them.
Free retest & attestation
We re-verify remediated findings and provide a letter of attestation you can share with customers, partners, auditors, and app stores.
