Mobile Application Penetration Testing
Mobile app pentesting, proven with exploits
Our certified testers put your iOS and Android builds through the full OWASP MASTG, prove every finding with a working exploit, and map each one to the compliance controls you answer for.
A mobile app ships its own attack surface: the binary sits on a device you don't control, talks to backends over networks you don't trust, and stores secrets an attacker can pull apart at leisure. SiegePoint tests the whole thing, the compiled app, its local storage, its transport, and the APIs behind it, the way a real attacker with a rooted phone and a decompiler would. Human testers validate and sign off every finding; our AI engine widens coverage so nothing quiet slips through.
What we test
Where we focus.
Insecure data at rest
Secrets in Keychain, Keystore, SQLite, plists, SharedPreferences, caches and backups.
Weak transport security
TLS misconfiguration, cleartext traffic, and certificate pinning we bypass with Frida.
Hardcoded secrets
API keys, tokens and credentials recovered from the binary, resources and strings.
Reverse engineering and tampering
Decompilation, patched binaries, and defeated root/jailbreak and anti-hooking checks.
Insecure IPC and deep links
Exported Android components, intent injection, and abusable iOS URL schemes and universal links.
Authentication and session handling
Biometric and PIN bypass, token storage, session fixation and reuse across devices.
Backend and API of the app
BOLA/IDOR, broken auth, mass assignment and business-logic flaws on the server side.
Client-side leakage
Sensitive data in logs, crash reports, screenshots, pasteboard and WebView storage.
How it works
From scope to retest.
Scope on a short call
We walk your iOS and Android builds, backends, user roles and platform versions, then fix the price and timeline before any work starts, no open-ended hourly meter.
Test against MASVS/MASTG
Testers instrument the app with Frida and objection on rooted and jailbroken devices, inspect storage and traffic, decompile the binary, and exploit the APIs behind it end to end.
Report with working proof
Every finding lands with a reproducible proof-of-concept, the exact device and build, business impact, a concrete fix, and a mapping to your SOC 2, ISO 27001, PCI DSS or HIPAA controls.
Retest once you fix
After your team ships remediations, we re-exploit each finding to confirm it's actually closed and reissue a clean report, included, not a paid add-on.
What you get
In your report.
- ✓A prioritized findings report, each issue rated by real exploitability, not scanner severity
- ✓A working proof-of-concept for every finding, with the device, build and steps to reproduce
- ✓Findings mapped to SOC 2, ISO 27001, PCI DSS and HIPAA controls for your auditors
- ✓Clear, developer-ready remediation guidance for iOS, Android and the backend APIs
- ✓A free retest after fixes and a clean re-issued report for customers and auditors
Questions
Answers, up front.
Do you need our source code, or just the app?
Either works. We can test purely black-box from the store or an .ipa/.apk, but sharing source and builds gets deeper coverage of business logic and secrets in the same fixed timeline.
Can you get past our root, jailbreak and pinning defenses?
Usually, yes, and that's the point. We use Frida, objection and patched binaries to bypass those controls, then show you exactly where they held and where they didn't.
Does this cover the app's backend and APIs?
Yes. The server-side APIs your app calls are in scope by default; we test them for BOLA/IDOR, broken authentication and business-logic flaws, since that's where the highest-impact bugs usually live.
