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

Among them, WhatsApp one most common smartphone communication, both as well legal At beginning, between server used therefore visible during wiretap. Early 2016 introduced end-to-end encryption users, immediately keeping around world dark. Existing research recuperate position limited single field investigation often post mortem on while wiretapping metadata information. Therefore, it provides only historical want continuous stream live substantive This paper identified that gap available scenarios methods forensic acquiring processing these scenarios. In paper, we propose approach create insight communication. Our based wiretapping, decrypting databases, open source intelligence Web analysis. We also evaluate our method different forensics prove its feasibility efficiency. Through scenarios, found by providing such profile pictures, their activity, voice video call behaviour including location remote access suspect account, conversations messages (live) geolocation, shared contacts, documents, images videos made accessible. Hence, corresponding can agencies reinforce interception.
