Penetration Testing Ten Popular Swedish Android Applications

Sammanfattning: As more services previously conducted physically are being conducted on mobiles, the security of mobile applications has become a more important part of the development. These mobile applications may handle sensitive information for the user such as payment data, health data, and other information that can have value for malicious actors. Therefore, it is crucial that the applications are secure against a various array of cybersecurity threats. This includes following data protection standards to secure the IT infrastructure surrounding the application from intrusion. This thesis aims to provide a general overview of the security for ten popular Android applications that are aimed at the Swedish Android user base. To evaluate the security of the applications, the process of ”penetration testing” was used to try find and exploit vulnerabilities. The results of the penetration testing process yielded no proper vulnerabilities in terms of being specific for the Android application software. Noticeable findings during the testing were business logic errors, meaning that they do not enable for further hacking and software exploitation. Our analysis of the results concluded that the main causes for the lack of vulnerabilities found likely has to do with rigorous software testing before release and the security practices in place when development applications of the scale tested.
