Understand the client's requirements, objectives, and specific concerns regarding their mobile application's security.

Define the scope of the penetration testing, including the mobile platforms (iOS, Android, etc.), application versions, and functionalities to be tested.

Gather information about the mobile application, including its architecture, technologies used, APIs, endpoints, and potential attack vectors.

Analyze potential threats and vulnerabilities based on the information gathered, including OWASP Mobile Top 10 vulnerabilities. Conduct a static & dynamic analysis of the mobile application's code and configuration files to identify potential security flaws.

Generate a comprehensive technical report detailing the methodology, findings, exploitation steps, and proof-of-concept demonstrations. Provide an executive summary highlighting key findings, risk assessment, and actionable recommendations in non-technical language.

Once the remediation has been completed, the tester may conduct a retest to verify that the vulnerabilities have been successfully addressed and that the application is now secure.
