Disclosure context

About Cuba

The Cuba ransomware group is a financially-motivated cybercriminal organization that emerged in February 2021 and has since conducted attacks against at least 105 known victims globally. The group operates as an independent ransomware operation with suspected ties to Russian-speaking cybercriminals, though their exact country of origin remains unconfirmed by law enforcement agencies. Cuba ransomware operators primarily gain initial access through compromised Remote Desktop Protocol (RDP) credentials, exploitation of Microsoft Exchange vulnerabilities, and phishing campaigns, subsequently deploying their custom Cuba ransomware payload which encrypts victim files while exfiltrating sensitive data before encryption as part of their double extortion strategy. The group has particularly targeted organizations in the United States, United Kingdom, France, Australia, and Belgium, with a notable focus on critical infrastructure sectors including healthcare, financial services, manufacturing, and energy companies. According to FBI reporting, the Cuba ransomware group has demanded ransom payments ranging from hundreds of thousands to millions of dollars from their victims. As of recent threat intelligence assessments, the Cuba ransomware group remains active and continues to pose a significant threat to organizations across multiple sectors and geographic regions. The group has been linked to 105 public disclosures across our corpus. First observed on a leak site on February 3, 2021; most recent post February 1, 2024. The operation is currently inactive.

Government agency records likely contain PII of workers, employers, and inspectors, and exposure of regulatory/enforcement data poses significant public and institutional harm.

The Cuba ransomware group claims to have attacked VDI and has published data ('data_published' status), though the leak post excerpt does not detail whether encryption, exfiltration, or both were performed; no ransom amount or data size has been specified.
