The Qardio Arm iOS application exposes sensitive data such as usernames and passwords in a plist file. This allows an attacker to log in to production-level development accounts and access an engineering backdoor in the application. The engineering backdoor allows the attacker to send hex-based commands over a UI-based terminal.
