FBI Carnivore Surveillance System

Record	OBS-0079
Category	Government/Surveillance
Status	PARTIALLY SUBSTANTIATED
Summary	Carnivore, later renamed DCS1000, was an FBI packet-sniffing system installed at ISPs to monitor email and internet traffic of criminal suspects under court order. Critics feared it could be used for mass surveillance, while the FBI maintained it was targeted and court-authorized. The system was used from 1997 to 2005, when it was replaced by commercial software.
Origin	Developed by the FBI in the late 1990s, publicly revealed in 2000, and used until 2005.
Claimed	Carnivore could monitor all internet traffic of a target user, including email and web activity. The FBI could use Carnivore to spy on the public without proper oversight. Carnivore was attached to major network backbones to scan all internet traffic for suspicious keywords. The FBI refused to release the source code, hiding its true capabilities.
Evidence / consensus	Carnivore was a real surveillance tool used by the FBI, but independent review found it did not have the capability to spy on almost everyone with an email account. It was used only with court orders, and its design was targeted rather than mass surveillance. However, privacy concerns were valid due to lack of transparency.

> OBSERVER NOTE:
A classic early-2000s surveillance panic. The tool existed, but the 'Big Brother' fears outpaced the technical reality. The name change to DCS1000 did little to calm the public.
