What is mobile app penetration testing?

What is mobile app penetration testing?

Mobile app penetration tests uncover and exploit vulnerabilities or misconfigurations in Android, iOS and other cross-platform applications. By revealing security flaws affecting mobile app architecture, mobile app pen tests provide actionable insights for building security by design features into your SDLC - ensuring compliance, protecting user data, and safeguarding your reputation. Our Android and iOS penetration testing services help secure mobile applications against unauthorised access, data breaches, and evolving threats.

Benefits of Mobile App Penetration Testing

  • Identify & Fix Security Flaws

    Uncover vulnerabilities such as insecure data storage, input validation issues, and weak authentication

  • Comply with Regulations

    Meet regulatory requirements related to mobile app security, such as GDPR, HIPAA, or industry-specific standards

  • Improve User Trust

    Demonstrating strong mobile app security reassures users and strengthens your organisation's reputation

How does mobile app pen testing work?

How does mobile app pen testing work?

During a mobile app pen test a qualified Bulletproof penetration tester takes on the role of a hacker and attempts to exploit a mobile application using the latest tools and technologies. The goal is to discover, document and prioritise all security flaws so that they can be remediated before cyber criminals exploit them.

We do this by using all methods available, including dynamic and static application security testing, DAST and SAST. SAST source-code reviews are insightful ways to uncover coding errors that could introduce security vulnerabilities. SAST can also help secure the software development lifecycle (SDLC), protecting data and preventing breaches at the earliest stages.

Mobile application penetration testing benefits

Mobile application penetration testing benefits

With mobile apps being prime targets for cybercriminals, security flaws can lead to data breaches, financial loss, and reputational damage. Mobile penetration testing helps you uncover the risks of your mobile application with minimal business disruption – ensuring your app is secure before release.

If your app collects or processes UK/EU user data, penetration testing is crucial for GDPR compliance. Regular mobile app security assessments strengthen your SDLC (Software Development Lifecycle) by identifying risks early.

  • Identify & exploit mobile security flaws before attackers do
  • Expose insecure functionality in your mobile app
  • Improve security throughout development & deployment

We know the threat landscape is dynamic and constantly evolving which is why we offer 12-months of free vulnerability scanning with every penetration test package.

Bulletproof mobile app pen testing methodology

Bulletproof follows industry standard best practices for our mobile penetration testing methodology

Scope definition & pre-engagement interactions

Based on your defined goals, we’ll work with you to develop a tailored testing strategy.

Intelligence gathering & threat modelling

In this reconnaissance stage, our experts use the latest groundbreaking techniques to gather as much security information as possible about the mobile apps in the scope.

Vulnerability analysis

This is the stage where our penetration testers use industry leading tools and sector knowledge to detect exploitable weaknesses in your mobile app’s architecture.

Exploitation

Using a combination of pre-existing software and custom-made exploits, our mobile pen testers will attempt to identify real-world attack vectors - without disrupting your business.

Post-exploitation

The team will determine the risks and pivot to other systems and networks if within the scope of the test. All compromised systems will be thoroughly cleaned of any scripts.

Reporting

Our security team will produce a comprehensive report with their findings. Once received, we’ll invite you for a collaborative read through. You’ll have the opportunity to ask questions and request further information on key aspects of your test.

Mobile app pen testing FAQs

Bulletproof mobile app penetration tests combine advanced automated tools with manual expertise to uncover security weaknesses, including OWASP Top 10 mobile vulnerabilities:

  • Improper Platform Usage
  • Insecure Data Storage
  • Insecure Communication
  • Insecure Authentication
  • Insufficient Cryptography
  • Insecure Authorisation
  • Client Code Quality
  • Code Tampering
  • Reverse Engineering
  • Extraneous Functionality

Yes, we conduct mobile penetration testing on both Android and iOS apps, covering platform-specific vulnerabilities and security risks. As Android and iOS apps have different security models, our penetration tests are tailored accordingly.

Integrating mobile app pen testing into your SDLC is the best way to ensure continuous security. As a minimum, it’s recommended to pen test your mobile app during its development and additionally just before you launch the app. It’s also recommended that mobile applications are tested at least once a year as well as after any significant UI or software updates.

  • Small mobile apps: 2-3 days
  • Medium mobile apps: 5-10 days
  • Larger mobile apps: 10 days+

All tests are tailored to you so use this as a guide.

Testing can be performed against a non-production replica of your live environment, such as a UAT/QA environment, to ensure no risk to your live services. If testing against production is unavoidable, we can coordinate our testing activities to minimise the impact. You can also specify things like no denial of service (DoS), meaning tests will have a negligible impact on your day-to-day operations.
