The FBI and international partners have at least temporarily disrupted the network of a prolific ransomware gang they infiltrated last year, saving victims including hospitals and school districts a potential $130 million in ransom payments, Attorney General Merrick Garland and other US officials announced Thursday.
“Simply put, using lawful means we hacked the hackers,” Deputy Attorney General Lisa Monaco said at a news conference.
Officials said the targeted syndicate, known as Hive, is among the world’s top five ransomware networks and has heavily targeted health care. The FBI quietly accessed its control panel in July and was able to obtain software keys it used with German and other partners to decrypt networks of some 1,300 victims globally, said FBI Director Christopher Wray.
How the takedown will affect Hive’s long-term operations is unclear. Officials announced no arrests but said, to pursue prosecutions, they were building a map of the administrators who manage the software and the affiliates who infect targets and negotiate with victims.
“I think anyone involved with Hive should be concerned because this investigation is ongoing,” Wray said.
On Wednesday night, FBI agents seized computer servers in Los Angeles used to support the network. Two Hive dark web sites were seized: one used for leaking data of non-paying victims, the other for negotiating extortion payments.
“Cybercrime is a constantly evolving threat, but as I have said before, the Justice Department will spare no resource to bring to justice anyone anywhere that targets the United States with a ransomware attack,” Garland said.
He said the infiltration, led by the FBI’s Tampa office, allowed agents in one instance to disrupt a Hive attack against a Texas school district, stopping it from making a $5 million payment.
It’s a big win for the Justice Department. Ransomware is the world’s biggest cybercrime headache with everything from Britain’s postal service and Ireland’s national health network to Costa Rica’s government crippled by Russian-speaking syndicates that enjoy Kremlin protection.
