Security analysis testing for secure instant messaging in android with study case: Telegram

Instant messaging activity plays a major role in our life. With increasing usage of mobile phones and instant messaging users, vulnerabilities against these devices raised exponentially. In this paper, we propose a security analysis testing for secure instant messaging apps in Android which is designed using a threat analysis, considering possible attack scenarios and vulnerabilities specific to the domain. To demonstrate the testing methodology, we subsequently analyze one of the popular instant messaging that promises security and privacy for its users, Telegram. Therefore, we give detailed discussion about vulnerabilities that help developer to design for further secure application developments.
