Mobile Security

Mobile Application Security

iOS and Android penetration testing that validates what an attacker can do after your app is installed on a device they control

Most mobile apps assume the device is trustworthy. An attacker doesn't give you that assumption. We test your app with root/jailbreak bypass, runtime instrumentation, and certificate manipulation — then confirm whether your backend holds up when the client is fully compromised.

Engagement Duration

5-10 business days

Primary Outcome

A complete finding set covering both client-side weaknesses and backend API trust failures — with platform-specific remediation your iOS and Android developers can implement directly.

How This Engagement Works

Scope and Threat Modeling

Human-led

We define your attack surface, trust boundaries, and the most likely attacker goals before testing begins.

AI-Assisted Discovery

AI-assisted

Automation expands coverage and surfaces anomalous patterns worth manual attention — no finding ships without human review.

Manual Exploit Validation

Human-led

Every finding is manually reproduced and confirmed by a senior analyst before it appears in your report.

Remediation and Free Retest

Collaborative

We provide developer-ready fix guidance and retest at no additional cost after your patch window closes.

What We Commonly Uncover

01

Authentication tokens persisted insecurely and accessible to other apps or attackers with device access

02

Sensitive data left in local storage, logs, or crash reports after sessions end

03

Client-side security controls that can be bypassed with basic runtime manipulation

04

Backend APIs that trust device-supplied values an attacker can freely forge

Client Runtime and Data Protection

A jailbroken or rooted device gives an attacker direct access to your app's runtime, memory, and local storage. We test from that position to find what's exposed when device trust assumptions break.

Local data handling in keychain/keystore and app storage

Transport protections including pinning behavior validation

Root/jailbreak and runtime tamper resistance checks

Sensitive artifact exposure in logs, cache, and backups

Mobile-to-API Trust Validation

Client-side controls are never enough. We validate whether your backend APIs enforce authorization independently — or silently trust data only a compliant client would send.

Token lifecycle integrity and session invalidation behavior

Backend authorization independence from client-side controls

Parameter tampering, replay, and sequencing abuse

Error handling and metadata leakage under adversarial requests

Reporting and Retest

Client-Side Findings

Validated issues in local storage, runtime controls, and transport behavior — with steps to reproduce on both platforms.

Backend Trust Findings

Evidence of API vulnerabilities that only surface when the client is compromised — the findings most teams never find.

Platform-Specific Remediation

Actionable fixes aligned to iOS and Android implementation realities, not generic mobile security advice.

Free Retest Validation

After remediation, we retest to confirm both client and API trust findings are fully closed.
