About Operation 404

The operation was launched as a massive anti-piracy campaign at the end of 2019. Brazilian law enforcement agencies launched this operation and dubbed it Operation 404 after the HTTP error code.

Authorities have been working with law enforcement in the UK and US. Since then, several waves of operations have followed one another under the names of operation 404.2 and operation 404.3. The operation spanned eleven states. So far, hundreds of pirate sites and streaming app domain names have been blocked.

The latest wave of the operation was titled Operation 404.4. However, authorities never named the suspects or the removed sites, but they did confirm that the apps alone had been downloaded ten million times. Sources have also confirmed that all of them are music-related apps.
