TOP THREE MOBILE APP VULNERABILITIES YOU SHOULD KNOW
1) Unauthorized Access: only install reputable apps and pay attention to access permissions requested by the application. Once permitted, apps can access sensitive data and upload it to a remote server without your knowledge.
2) No Encryption: many social networking apps transmit your contacts, calendar, and other data in plain text or un-encrypted. Anyone looking for it can obtain that information.
3) Authentication: some apps do not enforce strong authentication policies, allowing users to create weak or no passwords at all. Hence communication between the app and remote server can be compromised resulting in access to the server holding your data.
