Voice over Internet Protocol (VoIP) applications, such as WeChat, Whatsapp, or LINE, have gained increasing popularity during the last few years. Packets analysis of VoIP is one of the critical criminal investigation strategies for law enforcement agencies (LEAs). Due to its convenience and multi-functionality, the WeChat application is accessible by a massive amount of people in Asia, especially in Taiwan and China. Therefore, this study uses Wireshark to reveal the tool marks behind the WeChat messages and voice calls. It will be an excellent help for LEAs to identify cybercriminals and bring them to justice.
