Anonymous is taking credit for a confirmed breach of security at the U.S. Department of Justice, although the exact contents of the data bounty are not yet known. “Today we are releasing 1.7 GB of data that used to belong to the United States Bureau of Justice, until now,” reads an Anonymous press release, referring to the Department of Justice. “Within the booty you may find lots of shiny things such as internal emails, and the entire database dump.”

The hacktivist collective has been known to make bold claims, but a Department of Justice spokeswoman confirmed to Reuters that Anonymous members did indeed access a server that hosts the Department’s statistical data, including cybersecurity records. Anonymous released the data dump online through their usual torrent-based delivery system, but an attempted download of the data for further examination failed to complete.
