We also evaluate our method with different scenarios in WhatsApp forensics to prove its feasibility and efficiency. Our approach is based on the wiretapping, decrypting WhatsApp databases, open source intelligence and WhatsApp Web communication analysis. In this paper, we propose a forensic approach to create real-time insight in the WhatsApp communication. This paper identified that gap in available scenarios for law enforcement investigations and identified a gap in methods available for forensic acquiring and processing these scenarios. Therefore, it provides only historical data or metadata while law enforcement officers want a continuous stream of live and substantive information.

Existing research to recuperate the position of law enforcement is limited to a single field of investigation and often limited to post mortem research on smartphone or computer while wiretapping is limited to metadata information. Early 2016 WhatsApp introduced end-to-end encryption for all users, immediately keeping law enforcement officers around the world in the dark. At the beginning, WhatsApp communication between smartphone and server used to be in plain-text and therefore visible to law enforcement during a wiretap. Among them, WhatsApp is one of the most common smartphone applications for communication, both criminal as well as legal activities. Normal smartphone, computer or network investigations do no longer provide the contents of the communication in real-time when suspects are using apps like WhatsApp, Signal or Telegram. Regardless of the benefits for all law abiding citizens, this is considered to be the downside for criminal investigations.

These mobile applications replaced SMS-messaging and evolved the last few years from plain-text data transmission and storage to an encrypted version. On a daily basis, law enforcement officers struggle with suspects using mobile communication applications for criminal activities.
