The U.S. Federal Bureau of Investigation (FBI) published a flash report that states that at least 60 entities worldwide have been breached by BlackCat ransomware (aka ALPHV and Noberus) since it started its operations in November.
“The Federal Bureau of Investigation (FBI) has released a Flash report detailing indicators of compromise (IOCs) associated with attacks involving BlackCat/ALPHV, a Ransomware-as-a-Service that has compromised at least 60 entities worldwide.” reads the flash advisory. “CISA encourages users and administrators to review the IOCs and technical details in FBI Flash CU-000167-MW and apply the recommended mitigations.”
The BlackCat/ALPHV a Ransomware was first discovered in December by malware researchers from Recorded Future and MalwareHunterTeam. The malware is the first professional ransomware strain that was written in the Rust programming language.
BlackCat can target Windows, Linux, and VMWare ESXi systems, but at this time the number of victims is limited. The popular malware researcher Michael Gillespie said that the BlackCat ransomware is “very sophisticated.
Recorded Future experts speculate that the author of the BlackCat ransomware, known as ALPHV, was previously involved with the REvil ransomware operations.
ALPHV has been advertising the BlackCat Ransomware-as-a-Service (RaaS) on the cybercrime forums XSS and Exploit since early December. Like other ransomware groups, the gang also implements a double-extortion model, threatening to leak the stolen data if the victims don’t pay.
ALPHV is attempting to recruit affiliates for its operations, offering them between 80% and 90% of the final ransom, depending on its value. The BlackCat operations only hit a small number of victims at this time in the USA, Australia, and India.
Ransom demands range from a few hundreds of thousands up to $3M worth of Bitcoin or Monero.
The alert includes indicators of compromise (IoCs) associated with BlackCat/ALPHV, as of mid-February 2022.
The FBI is seeking any information that can be shared related to the operations of the BlackCat ransomware operation.
Below are recommended mitigations included in the alert:
