Monitoring WhatsApp and Facebook user activity is a simple process for the FBI, according to recently obtained and published agency document.
The document obtained by "Rolling Stone" magazine outlines ways in which the agency legally obtains messages and metadata on communication apps also including Telegram and Viber.
The document appears to show iMessage and WhatsApp are the services that provide the FBI with the most access to data including content and history of messages sent and received.
WhatsApp, in fact, was revealed to be the only one of the apps included in the document that produces certain user metadata every 15 minutes, meaning that even without a request from law enforcement for message content, WhatsApp's metadata clocks who and when someone is messaging, in addition to which contacts a user keeps in their address book.
