Definition

What Is Mobile Penetration Testing?

Understand how mobile application penetration testing assesses iOS and Android apps, local data and backend interactions.

Mobile penetration testing is a controlled, manual security assessment where CREST-certified ethical hackers simulate real-world attacks against your iOS and Android applications, mobile APIs and backend services. The goal is to identify exploitable mobile vulnerabilities such as insecure storage, weak authentication, poor session handling, SSL pinning bypass, exposed secrets, reverse engineering risks and account takeover paths before attackers find them.

Unlike automated mobile scanning, a true mobile penetration test validates how the app behaves on real devices, rooted or jailbroken environments, intercepted traffic, manipulated API requests and abused user workflows. A skilled tester chains mobile, API and logic weaknesses into high-impact attack paths and produces a short, prioritised list of confirmed, exploitable findings with proof-of-concept evidence, business impact and developer-ready remediation guidance.

For Australian businesses, mobile penetration testing is strong evidence for ISO/IEC 27001:2022 controls A.8.8 and A.8.29, SOC 2 Trust Services Criterion CC7.1, PCI DSS Requirement 11.4, APRA CPS 234, and customer security reviews.

Use Cases

When You Need a Mobile App Pentest

Most Australian businesses engage Penva Security for one of six clear mobile app risk triggers; each maps to a compliance requirement, customer assurance request, app release, or high-impact security event.

Pre-Launch Assurance

Before launching a new product, customer portal, or major feature release. Identifies vulnerabilities while remediation is cheapest - pre-production.

Annual Compliance

ISO 27001, SOC 2, and PCI DSS all expect at least an annual web application pentest. Auditors require a CREST-certified report as evidence.

After Major Changes

New authentication flows, payment integrations, role/permission changes, or framework upgrades - PCI DSS Req. 11.4 mandates testing after any significant change.

Vendor Security Questionnaires

Enterprise procurement and government supply-chain customers increasingly demand evidence of independent CREST-accredited penetration testing before signing.

APRA CPS 234

Financial services entities regulated by APRA must regularly test the effectiveness of information security controls - and demonstrate that testing to the regulator.

Post-Incident Review

After a near-miss, breach, or suspicious activity. Validates whether the underlying cause has been remediated and identifies adjacent weaknesses.

Coverage

Mobile Penetration Testing Approach

Every Penva Security mobile engagement follows OWASP MASVS, OWASP MASTG, OWASP ASVS, NIST SP 800-115, and PTES. We test iOS apps, Android apps, mobile APIs and backend workflows the way attackers do: by chaining client-side, device, network, authentication and API weaknesses to demonstrate real business impact.

Local Storage and Sensitive Data

Check app files, logs, caches and backups for exposed credentials, personal data and session tokens.

Authentication and Account Recovery

Test sign-in, multi-factor authentication, password resets and account recovery for bypasses and account takeover paths.

Session and Token Handling

Review token storage, expiry, refresh and logout behaviour across the app and its backend.

Mobile API Access Controls

Test whether users can read or change another account's records, cross tenant boundaries or call privileged API functions.

Network Traffic and TLS

Inspect app traffic, certificate validation and transport security to identify data exposure and interception risks.
Application security testing coverage

Reverse Engineering and Exposed Secrets

Inspect application packages for hard-coded keys, sensitive configuration and information that could help an attacker.

Platform Permissions and Components

Review Android exported components, iOS URL schemes, deep links and permissions for unintended access.

Runtime and Device Security

Assess security controls on rooted or jailbroken test devices and check how the app handles runtime manipulation.

Business Logic and Payment Workflows

Test the agreed payment, approval and account workflows for request manipulation, replay and missing server-side checks.

WebViews and Third-Party Integrations

Review embedded web content, JavaScript bridges and integrations for unsafe trust boundaries and data handling.
