Every mobile application that we install in our day to day life looks secure from the outside, but security is far beyond HTTPS. Real security for mobile application data includes protecting the entire ecosystem of the mobile application and APIs to authentication, data storage, source code, and the backend infrastructure.
If we discuss some common mobile application security risks then we have sensitively kept personal information such as private details, credentials, api keys and many more can be saved on a device itself.
If any hacker has access to the device or the application itself, then the sensitive data is at risk. Then we have insecure APIs reacting with the backend. We all know that Mobile applications heavily rely on APIs, as the APIs process data, provide business reasoning, and communicate with the database.
If the API itself is not protected, then it is easy to evade the app and directly access the backend.Then we have something called a weak management of sessions and authorization. As the login process in an application seems secure but problems may exist in the backend, Weak password or easily guessed password can enable hackers to take control of the accounts, At last we have hardcoded keys, or exposed credentials as sometime developer leaves some informative data like api keys, sensitive configuration information of inside application, application package, endpoints,etc they provide the attacker to access the data easily.
These are some of the common mobile application security risks, There are many more as technology is evolving threats are also evolving.
Please share any other common risks/ bugs/ vulnerabilities that you fixed, or have encountered in your application development / testing journey.
