FBI Liaison Alert System Reports

Overview
Working with its interagency partners and the Intelligence Community writ large, the FBI works to declassify both contextual and technical information for dissemination to private industry through FBI Liaison Alert System (FLASH) reports. FLASHes convey industry-specific details about current or emerging cyber threats and trends, along with high-level analytical or technical information of use to the recipient to identify the threat. FLASH reports provide technical reporting to interagency and industry for immediate action against an ongoing threat and contribute to investigative efforts. Additionally, the FBI, along with other agencies, disseminates unclassified Joint Intelligence Bulletins (JIBs), which also provide cyber threat information.
