Break your mobile app before someone else does.
We manually pentest your Android and iOS apps: decompiling binaries, instrumenting them at runtime, and attacking the APIs behind them. Tested against OWASP MASVS and MASTG, so you see exactly what an attacker can reach, exploit, and exfiltrate. Every engagement ends with a fix-focused report and a verification retest.

Manual, exploit-driven pentesting for iOS and Android apps, aligned to OWASP MASVS.
Mobile Security is a full penetration test of your mobile app and its supporting back end. We combine static analysis and reverse engineering of the compiled binary with dynamic, on-device testing: hooking the running app, intercepting its traffic, and manipulating its behavior to find flaws that automated tools consistently miss. The goal is not a checklist; it is a set of proven, exploitable findings with the evidence to reproduce them and the guidance to close them.
Mobile apps carry a different risk surface than web apps: the client is in the attacker's hands. Secrets embedded in the binary, data cached in insecure storage, weak or homegrown crypto, bypassable root/jailbreak checks, and over-trusted APIs are all reachable once the app leaves your control. If your app handles money, health data, identity, or payments, these are the exact weaknesses that lead to account takeover, data exposure, and fraud.
Our testing is led by senior engineers with hands-on reverse-engineering, exploit development, and secure-coding backgrounds. We map every finding to the OWASP Mobile Application Security Verification Standard so your team, and your enterprise customers, can see exactly what was covered and where you stand.
What we test and deliver
Depth over checklists. Every capability below is hands-on work performed and validated by our engineers.
Static analysis and reverse engineering
We decompile and inspect the APK/IPA and native libraries for hardcoded secrets, API keys, debug endpoints, exported components, and insecure logic, recovering the app's real behavior even when it is obfuscated or shipped as compiled code.
Dynamic and runtime testing
On real devices and rooted/jailbroken environments we instrument the running app (Frida/Objection-style hooking), intercept and tamper with traffic, and manipulate runtime state to force the app down unsafe paths and prove exploitability.
Insecure data storage assessment
We examine everything the app persists (Keychain/Keystore usage, SQLite databases, shared preferences, plists, caches, logs, and backups) to find sensitive data (tokens, PII, financial records) stored unencrypted or recoverable from the device.
Cryptography review
We assess algorithms, key generation and storage, TLS configuration, and how crypto is actually used in code, flagging weak ciphers, hardcoded keys, predictable IVs, and homegrown schemes that give a false sense of protection.
Client-side control resilience
We attempt to bypass certificate pinning, root/jailbreak detection, and anti-tampering and anti-debugging controls to determine whether these protections withstand a determined attacker or merely slow one down.
API, back-end, and IPC testing
We attack the server-side APIs the app depends on (authentication, authorization, IDOR, and business-logic flaws) and test inter-process communication (deep links, intents, exported activities, custom URL schemes) for injection and unauthorized access.
Who it's for
- Fintech, neobank, and payments teams shipping apps that move money or store financial data
- Digital health and medtech products handling patient data and sensitive PII
- Consumer apps at scale with logins, wallets, or in-app purchases worth attacking
- Startups facing enterprise security due diligence or a customer security questionnaire before a deal
- Product and engineering teams that need MASVS-aligned assurance before a major release or app-store submission
Why HACK KAP
- Manual, exploit-driven testing: we prove impact by exploiting issues, not just flagging what a scanner reports
- Genuine reverse-engineering depth: senior engineers who read decompiled and native code, not only surface behavior
- Testing across real devices and rooted/jailbroken environments and multiple OS versions, not a single emulator
- A verification retest is included, so you leave with confirmation that fixes actually hold
- Senior-led engagements with direct access to the testers: the people who found the bug explain how to close it
Exactly what you receive
No vague promises. Each engagement produces concrete, shareable artifacts your team, auditors, and customers can rely on.
Scoping and threat-model document
A written plan agreed before testing begins: in-scope platforms and builds, target APIs, test accounts, assumptions, and the attacker profiles we will simulate, so there are no surprises about what we touch.
Technical findings report
Every vulnerability documented with a severity rating, business impact, step-by-step reproduction, request/response and code evidence, and a concrete, developer-ready remediation for each issue.
Executive summary
A concise, non-technical readout for founders, CISOs, and boards: overall risk posture, the themes behind the findings, and what to prioritize, suitable to share with stakeholders and prospective customers.
MASVS coverage mapping
An appendix mapping our testing to OWASP MASVS control groups and MASTG test cases, so you can evidence exactly what was assessed and demonstrate methodology alignment to auditors and enterprise buyers.
Remediation walkthrough
A live session with your engineers to explain root causes, answer questions, and agree fixes, turning the report into resolved issues rather than an unread PDF.
Verification retest and letter
After you remediate, we re-test the reported issues to confirm they are actually fixed and issue a summary letter you can share with customers, partners, or auditors.
Our engagement methodology
A transparent, repeatable process. You always know what's happening, what's next, and where you stand.
- 01
Scoping and threat modeling
We agree platforms, builds, in-scope APIs, and test accounts, sign an NDA, and model the attacker profiles and abuse cases most relevant to your app, mapping the plan to OWASP MASVS before any testing starts.
- 02
Environment and build setup
We provision test devices and rooted/jailbroken environments across relevant OS versions, load the target build, and confirm connectivity to your staging or test back end so testing is realistic and safe.
- 03
Static analysis and reverse engineering
We decompile and review the binary and its resources, hunting for secrets, insecure configuration, and weak logic, to build a map of the attack surface before we go dynamic.
- 04
Dynamic testing and exploitation
We run the app under instrumentation, intercept and manipulate traffic, bypass client-side controls, probe storage and crypto, and attack the APIs and IPC, chaining findings into real, demonstrated exploits.
- 05
Reporting and readout
We deliver the technical report and executive summary, then walk your team through each finding, its impact, and the recommended fix in a live remediation session.
- 06
Remediation support and retest
As you fix issues we stay available for questions, then re-test the reported vulnerabilities to verify they are resolved and issue your retest letter.
Questions, answered
The things teams most often ask before an engagement. Don't see yours? Just reach out.
Typically a test build (APK/IPA) or store/TestFlight access, credentials for a few test accounts across relevant roles, and connectivity to a staging or non-production back end. We define scope together up front (platforms, target APIs, and any exclusions) and capture it in a written scoping document. We sign an NDA before kickoff, so you can share builds and details safely.
