Abstract

Whatsapp is a messaging application for smartphones that can be used across platforms including Apple iOS, Android, Windows Phone, etc. popularity Whatsapp's among the public can be misused for negative purposes for the development of society itself. One example of a case that often occurs in the community is extortion through the application Whatsapp. This study will carry out a scenario of a crime of extortion that occurs using Whatsapp Web, Whatsapp runs on the Chrome Browser, this research uses the NIJ stage. The stages of the forensics National Institute of Justice (NIJ)are preparation, collection, examination, analysis, and reporting. This research uses a laptop with a condition that is connected to the internet and accesses Whatsapp via the Chrome browser. The process of collecting digital evidence through forensic tools, namely Belkasoft RAM Capturer, FTK Imager, Browser History Capturer, and Browser History Examiner. This research produces digital evidence, namely information on profile photos of perpetrators and victims, when accessing WhatsApp Web, WhatsApp Weblinks accessed via Chrome, as well as evidence of extortion chats that have been deleted by the perpetrators. The percentage of results obtained from the results of imaging data analysis using the FTK Imager tool is 50% in the form of a WhatsApp Web link and chat from the perpetrator to the victim, while the results from the Browser History Examiner are 50% in the form of a cache of the photo perpetrator, as well as the access time WhatsApp.This research uses the stages of the National Institute of Justice (NIJ), it is hoped that future research can use other stages. This research uses OS Windows 10, so it is hoped that for further research it can use OS Linux or macOS.
