Carnivore, later renamed DCS1000, was a system implemented by the Federal Bureau of Investigation that was designed to monitor email and electronic communications. It used a customizable packet sniffer that can monitor all of a target user’s Internet traffic. Carnivore was implemented in October 1997. By 2005 it had been replaced with improved commercial software.
In June of 2018, I requested all FBI documents about the system. In July of 2018, I received the first release of records. The request is still open for additional records to be released. This page will be updated once complete.
