\r\n\t

About Our Client<\/h3>

The client is one of the largest financial service providers and they offer comprehensive suite of financial products and their business includes Retail, Corporate and International Banking services, Insurance, Mutual Funds, Mortgage services and other financial services.<\/p>

Objective<\/h3>

The client sought Varutra for advice on securing their Mobile Applications from security threats which can lead to loss of Confidentiality, Integrity and Availability (CIA) of the data. Client wanted to ensure that their Mobile Applications meet all the security standards.<\/p>

The Challenge<\/h3>

Our Client\u2019s business requirement was to provide mobility to all their customers for all finances. To fulfil the same, Android & iOS applications were developed to provide mobility to the customers via cross-platform support.<\/p>

Major concern was to secure the customer\u2019s sensitive data, client being from financial background has developed applications considering all secure configurations like SSL Pinning and root detection implemented.<\/p><\/div><\/div>\r\n\t<\/div>\r\n\r\n\r\n\t\t\r\n\r\n<\/div>\r\n\r\n

Our Approach<\/h3><\/div><\/div>\r\n\r\n
\r\n\t

Varutra\u2019s methodology involves assessing the security posture of the mobile applications to find out vulnerabilities (if any). To check the security of mobile application and server systems from an attacker\u2019s point of view; specifically, as an internet malicious user, determine if the mobile application and server could be compromised to gain access impacting Confidentiality, Integrity and Availability of data.<\/p>

  • Pentest activity started with gathering information for the mobile application and technologies used on frontend and backend systems.<\/li>
  • Reverse engineering the iOS and Android mobile application in order to better understand the interactions between the application layer and server.<\/li>
  • Pentesting via Black box testing methodology which helped to gain more knowledge about technologies used.<\/li>
  • At the end of Black box testing, many critical and high vulnerabilities be discovered which includes authentication bypass and 2FA bypass and others.<\/li>
  • Test cases were prepared by Pentesters to test critical modules of the application.<\/li>
  • Pentesters initiated Grey box testing wherein they checked internal storage and business logic.<\/li><\/ul><\/div><\/div><\/div><\/div>\r\n\t<\/div>\r\n\r\n\r\n\t\t\r\n\r\n<\/div>\r\n<\/div>\n\n\t<\/div>\r\n<\/section>\r\n\r\n

    Key Findings & Observations<\/h3>

    Varutra, with its skilled Pentesters, was able to break into the mobile application by finding multiple Critical vulnerabilities such as,<\/p>

    • SSL Pinning Bypass<\/li>
    • Improper Export of Android Application Components<\/li>
    • Authentication Bypass<\/li>
    • Sensitive data in local storage and logs<\/li><\/ul><\/div><\/div>
      • Application allows runtime debugging<\/li>
      • SQL Injection<\/li>
      • Cross-Site Scripting (XSS)<\/li>
      • Improper Session Management<\/li><\/ul><\/div><\/div><\/div><\/div>

        The complete assessment was done with the automated testing using commercial and open source tools as well as extensive manual testing for verification and validation. This was the most important phase of a penetration test because it effectively demonstrates the impact of breach for the concern organization. Main targets in this phase were sensitive information revealed by the mobile application which includes sensitive API Keys, Hard coded credentials, Credit card details transmitted via logs.<\/p><\/div><\/div>\r\n\t<\/div>\r\n\r\n\r\n\t\t\r\n\r\n<\/div>\r\n<\/div>\n\n\t<\/div>\r\n<\/section>\r\n\r\n

        Conclusion<\/h3><\/div><\/div>\r\n\r\n
        \r\n\t

        Penetration testing is often done for varying reasons. Two of the key goals we and our client aimed for, were to increase upper management awareness of security issues and to test intrusion detection and response capabilities. After conducting the Pentest and compromising the organization & engaged the client in a controlled offensive\/defensive threat detection challenge, allowing the client several days to identify and remediate active threats within their systems.<\/p>

        Post completion of the assessment, Varutra was appointed to conduct training for the key internal security team like secure code development as well as further advisory on remediation tactics. In the end our client was able to meet the highest level of compliance and regulation standards, develop better security practices and reassure their customers, employees, and board of their continued dedication to best business practices and continued growth.<\/p>

        After mitigating all security risks by following all remediations suggested by Varutra, the client mobile application was secure from all possible risks uncovered by Varutra and effectiveness of these vulnerabilities can be verified by conducting Reassessment activity on same target mobile applications to analyze strength and the security posture. <\/p><\/div>\r\n\t<\/div>\r\n\r\n\r\n\t\t\r\n\r\n<\/div>\r\n<\/div>\n\n\t<\/div>\r\n<\/section>\r\n<\/p>","protected":false},"excerpt":{"rendered":"
