Mobile Assessment

Methodology

Our Approach

We assess a mobile app as a complete system, the code running on the device and the services it talks to, mapping both to the OWASP MASVS/MASTG standard so nothing gets tested in isolation.

On-Device Testing

// the client

Static & dynamic analysis: we examine the app at rest and while running to surface flaws the two views expose together.
Insecure data storage: auditing how sensitive data is written, cached, and left behind on the device.
Weak cryptography: reviewing algorithms, key handling, and how encryption is actually applied in practice.
Hardcoded secrets: hunting for embedded keys, tokens, and credentials shipped inside the binary.
Certificate pinning & jailbreak/root checks: testing the strength of transport validation and device-integrity defenses.
IPC & deep-link handling: probing inter-process communication and deep-link routes for abuse and injection.
Reverse-engineering resistance: gauging how well the app resists tampering, repackaging, and inspection.

API & Backend Testing

// behind the app

Authentication & session handling: validating login flows, token lifecycles, and how sessions are issued and revoked.
Authorization & access control: confirming users can only reach the data and actions they are entitled to.
Business-logic abuse: chaining legitimate features in unintended ways to break workflows and assumptions.
Server-side APIs: testing the backend services the app depends on, where much of the real risk lives.
MASVS/MASTG alignment: grounding every backend test in the OWASP Mobile Application Security standard.

Why Arcanum

Depth you can act on

Mobile is its own discipline. Our team brings full-stack coverage and a standards-aligned method to every engagement.

Full-Stack Coverage

We test the app and the APIs behind it as one system, so client-side and server-side risk are never assessed apart.

MASVS-Aligned Methodology

Every engagement maps to the OWASP MASVS/MASTG standard, giving you repeatable, defensible, industry-recognized coverage.

Both Platforms

iOS and Android alike, static and dynamic analysis tuned to the quirks and defenses of each ecosystem.

Bug-Hunter Depth

A team steeped in real-world bug hunting goes past checklists to the logic flaws and chains that automated tools miss.
