U.S. infiltrates large ransomware gang along with international partners
by Associated Press
Criminals using Hive's ransomware-as-a-service tools targeted a wide range of businesses and critical infrastructure, including government, manufacturing and especially health care.
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 U.S. officials announced on Jan. 26.
“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 Jan. 25, 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.
The criminals lock up, or encrypt, victims’ networks, steal sensitive data and demand large sums. Their extortion has evolve to where data is pilfered before ransomware is activated, then effectively held hostage. Pay up in cryptocurrency or it is released publicly.
As an example of a Hive sting, Garland said it kept one Midwestern hospital in 2021 from accepting new patients at the height of the COVID-19 epidemic.
The online takedown notice, alternating in English and Russian, mentions Europol and German law enforcement partners. The German news agency dpa quoted prosecutors in Stuttgart as saying cyber specialists in the southwestern town of Esslingen were decisive in penetrating Hive’s criminal IT infrastructure after a local company was victimized.
In a statement, Europol said companies in more than 80 countries, including oil multinationals, have been compromised by Hive and that law enforcement from 13 countries was in on the infiltration.
A U.S. government advisory last year said Hive ransomware actors victimized over 1,300 companies worldwide from June 2021 through November 2022, netting about $100 million in payments. Criminals using Hive’s ransomware-as-a-service tools targeted a wide range of businesses and critical infrastructure, including government, manufacturing and especially health care.
