Officials from the Federal Bureau of Investigation (FBI) say Cuba ransomware operators earned at least $ 43.9 million this year.
In an emergency warning released the other day, the FBI writes that the Cuba group has “compromised at least 49 organizations in five critical infrastructure sectors, including the financial and public sector, healthcare, manufacturing and IT.”
Law enforcement officials say they tracked Cuba’s attacks on systems infected with the Hancitor malware, which uses phishing emails, compromised credentials, or brute-forcing RDP to access vulnerable Windows machines and exploits vulnerabilities in Microsoft Exchange. After Hancitor is infected, access to such a system is leased to other hackers using the Malware-as-a-Service model.
While a McAfee report on Cuba last year found no link between the two groups, the FBI document says that now there appears to be a new partnership between the MaaS vendor and the ransomware. The published FBI document describes how a typical Hancitor-to-Cuba infection occurs and lists indicators of compromise.
The Record writes that before encrypting the victims’ data, Cuba operators steal information and then threaten to publish these files on their website on the darknet if the victim does not pay the ransom. According to data compiled by analysts at Recorded Future, the site has already listed 28 companies that have refused to pay.
Let me remind you that we also reported that Hive ransomware infected by MediaMarkt and its operators demand $ 240 million.
