WhatsApp Group Chat Analysis using ELK

The Elastic Stack is becoming increasingly popular with security analytics with any form of log inputs.¬† In this post, we learn about how ELK can be used for analyze the messages in a WhatsApp group and to generate some interesting visualizations and reports. The “Email chat” feature is used to send the group chat messages to an email with media omitted and the text file containing the chat messages is downloaded from the email and copied to a filebeat installation folder. Once the file is copied the messages from the text file are pushed to the logstash beat sensor.
