[JURIST] The FBI [official website] has been forced to shut down part of the e-mail system it uses to communicate with the public because of a security breach. The FBI is investigating the source of the intrusion, although there is no indication that internal communications have been effected. The breach comes one day after the FBI released its response [FBI letter] to a report [DOJ website] by US Department of Justice Inspector General Glenn Fine [DOJ profile] that criticized the bureau's information technology management. The report said that the FBI's Virtual Case File System [FBI report; audio backgrounder from Bob Chiaradio, FBI Executive Assistant Director for Administration], designed to better manage criminal and terrorism cases, does not work and will have to be replaced. AP has more.
