ShinyHunters hackers claim breach of Florida "DAVID" DMV database

DAVID is the "Driver and Vehicle Information Database" platform operated by the Florida Highway Safety and Motor Vehicles (FLHSMV) agency, used by law enforcement and officials to look up information about a particular driver. As proof of the breach, the threat actors released a screenshot of Jeffrey Epstein's record in the DAVID system. This record includes the person's address, Social Security number, birth date, driver's license ID, issuance and expiration dates, and registered vehicles. The system also has tabs for additional information, including driver's license transactions, addresses, insurance, prior vehicles, and parking permits. They claim to have stolen 200,000 records. (I would also like to note that DAVID was one of the tools a Florida police officer recently used to stalk a woman after she turned him down for a date.)
