Mobile Application Penetration Testing Services

We test login mechanisms, biometric authentication implementation, token handling, and session persistence for weaknesses that could allow unauthorized access. Authorization testing confirms users can only access data and functionality appropriate to their account and role, including checks for privilege escalation.

Mobile apps often maintain long-lived sessions for user convenience, which can introduce risk if not implemented securely. We test session token handling, expiration, and revocation, alongside broader access control logic, to identify gaps that could allow session hijacking or unauthorized persistent access.

This is one of the most critical areas of mobile testing. We examine how sensitive data is stored locally on the device (databases, shared preferences, keychains, cache files) and how data is transmitted between the app and backend services, checking for unencrypted storage, insecure transmission, and data leakage through logs, backups, or clipboard exposure.

Mobile apps rely heavily on backend APIs, and testing the app in isolation without examining those APIs leaves significant risk unassessed. We test the APIs the mobile app depends on for authentication weaknesses, improper access controls, and data exposure, since backend flaws are frequently more damaging than issues in the app itself.

We assess how the app handles network communication, including whether it properly validates SSL/TLS certificates, implements certificate pinning where appropriate, and resists man-in-the-middle interception attempts that could expose data in transit.

Weak or improperly implemented cryptography is a common mobile vulnerability. We evaluate how encryption is used for data storage and transmission, how cryptographic keys are generated and stored, and whether the app relies on outdated or insecure algorithms.

We analyze the compiled application binary for hardcoded secrets (API keys, credentials, tokens), insufficient obfuscation, debug code left in production builds, and reverse-engineering risks that could expose business logic or backend infrastructure details to an attacker.

Every engagement is mapped against the OWASP Mobile Top 10, ensuring systematic coverage of the vulnerability categories most commonly found in real-world mobile applications, including insecure data storage, insufficient cryptography, insecure authentication, and reverse engineering risks.

Each finding is documented with severity ratings based on exploitability and business impact, supported by technical detail for developers and a clear executive summary for stakeholders who need to understand risk without technical depth.

We provide specific, actionable remediation guidance tailored to the platform and framework your app is built on, giving your development team clear direction rather than generic advice that doesn't account for mobile-specific constraints.

Findings are validated through controlled testing wherever safe and appropriate, confirming that identified weaknesses represent genuine, exploitable risk rather than theoretical concerns. This gives you an accurate, prioritized view of what actually needs attention.

HashRoot includes retesting after remediation to confirm vulnerabilities have been properly fixed and are genuinely closed, not just marked resolved. This closes the loop between finding, fixing, and confirming your app is actually more secure than before.
