Overview

Client is a leading technology services provider that offers scalable and IT and computing solutions. Client operates with a mission of providing world-class IT infrastructure and powerful networking solutions. They are providing superior customer experiences and innovative solutions.

Client Requirement

Client required someone to analyze the security emails they were getting for vulnerabilities in one of their mobile applications. The android application that they had developed had not been updated since it was developed. Client wanted experts to take a thorough look at the code and test it for vulnerabilities and also perform penetration testing so as to ensure that the application can be secured and used without any potential threat. Client was looking for a VAPT service provider in India to take a look at the Android application and offer expert advice and solutions.

How did ECS provide a solution?

  • It was necessary to analyze the application and identify the vulnerabilities and risks involved.
  • Code Vulnerability Assessment was done and after thoroughly understanding the loopholes or errors, ECS was able to draw up a plan to minimize the errors that could lead to major cyberattacks.
  • The current security settings weren’t enough and safeguards needed to be put into place.
  • A detailed plan for remediation by detecting existing flaws or malicious code was prepared.

ECS performed two types of analysis

1. Static Analysis

We decompiled the entire codebase and checked the code manually. We also used tools such as MobSF and JADX-GUI to detect any flaws in the code.

2. Dynamic Analysis

  • We used tools such as BURP SUITE to find vulnerabilities.
  • ECS followed a checklist and created a custom checklist under the guideline of OWASP Top 10 Vulnerabilities
  • We were able to cover all the security loopholes.
  • Documentation and daily reporting enabled client to patch all vulnerabilities and monitor how VAPT (Vulnerability Assessment and Penetration Testing) is done.

Results

After a thorough analysis, ECS performed VAPT (Vulnerability Assessment and Penetration Testing) for the customer’s Android mobile application. Penetration testing allowed the identification of several vulnerabilities.

  • We discovered very critical security weaknesses in the mobile application
  • ECS helped tighten the Mobile app protection level
  • Our Team has also prepared a customized plan for regular testing and updates of the app.

Following are the vulnerabilities found by ECS after Dynamic Analysis:

  • OTP Bypass
  • IDOR (In-direct Object Reference)
  • Hard coded Google API Keys

The Customer was satisfied with the approach that ECS took for securing the application and expressed their intention to continue collaboration with ECS as a trusted provider of vulnerability assessment penetration testing services. ECS is one of the leading firms offering VAPT Services in India.

Conclusion

ECS not only helped securing the mobile application, but also helped the customer by preparing a detailed security plan that includes regular audits that should be conducted. Retest phase included patching the app with appropriate updates and then recheck the functionalities. Day-to-day reports and a final report with all the findings and the implemented solution was submitted. Client was able to use the Android application without any fear of a possible vulnerability that could put their entire data at risk. We successfully made sure that the code is threat-free.

FAQ’s

1. What is mobile app VAPT?

Mobile app VAPT combines vulnerability assessment and penetration testing to identify and validate security weaknesses in mobile applications such as Android apps.

2. What is Android VAPT?

Android VAPT is the security testing of Android applications to identify vulnerabilities in areas such as authentication, APIs, data storage, encryption, network communication and application logic.

3. Why is Android app security testing important?

Android app security testing helps organizations identify security weaknesses that could expose sensitive data, compromise accounts or allow attackers to abuse application functionality.

4. What does mobile application VAPT test?

Mobile application VAPT can assess authentication, authorization, APIs, local data storage, encryption, network communication, session management, business logic and application security controls.

5. What is the difference between vulnerability assessment and penetration testing?

Vulnerability assessment identifies potential security weaknesses, while penetration testing validates vulnerabilities through controlled security testing to determine their practical impact.

6. What is the Android VAPT testing process?

A typical Android VAPT process includes reconnaissance, APK analysis, static and dynamic testing, API testing, network testing, vulnerability validation, reporting and retesting.

7. Which tools are used for Android VAPT?

Common Android security testing tools include MobSF, JADX, apktool, Frida, Objection, Burp Suite, OWASP ZAP and ADB, depending on the testing scope.

8. How is Android VAPT different from web application VAPT?

Android VAPT includes mobile-specific testing such as APK analysis, local storage, reverse engineering and mobile platform security, while web VAPT focuses primarily on web applications and their supporting infrastructure.

9. How does mobile VAPT help protect sensitive data?

Mobile VAPT can identify weaknesses in local storage, encryption, authentication, authorization and network communication that may expose sensitive application or user data.

10. How often should a mobile application undergo VAPT?

Mobile applications should be tested regularly and after significant application changes, major releases, security changes or new APIs are introduced. Organizations may also align testing with their risk and compliance requirements.

11. How do I choose a mobile VAPT company in India?

Look for a provider with mobile security expertise, manual and automated testing capabilities, API testing, detailed reporting, remediation guidance and post-remediation retesting.

12. Does Android VAPT include API security testing?

Yes. API security testing is an important part of mobile application VAPT because mobile applications commonly rely on backend APIs for authentication, data access and business functionality.

13. What does an Android VAPT report contain?

A professional report generally includes the scope, methodology, identified vulnerabilities, severity ratings, evidence, business impact, technical details, remediation recommendations and retesting results.

14. How much does mobile app VAPT cost in India?

Mobile app VAPT pricing varies based on application complexity, testing scope, number of APIs, testing approach, manual testing requirements and retesting needs.

15. Can VAPT be performed on both Android and iOS applications?

Yes. Mobile application VAPT can be performed on Android and iOS applications, although the testing approach and platform-specific security considerations differ.
