About Black Basta

Black Basta is a RaaS that emerged in early 2022 and is assessed by some researchers to be an offshoot of the disbanded Conti and REvil attack groups. The group routinely exfiltrates sensitive data from victims for additional extortion leverage. Black Basta engages in highly targeted attacks and is assessed to only work with a limited group of highly vetted affiliate attackers. Black Basta has quickly became one of the most prolific attack groups in 2023 and was observed leveraging unique TTPs for ingress, lateral movement, data exfiltration data, and deployment of ransomware payloads.

Ransom Demands and Revenue

Ransom demands vary depending on the targeted organization with reports that they can be as high as $2 million dollars. It is estimated that Black Basta exceeded $107 million in ransom revenue from more than 90 victims in less than two years.

Technical Details of Black Basta Ransomware

Black Basta continues to evolve their RaaS platform, with ransomware payloads that can infect systems running both Windows and Linux systems. Black Basta is particularly adept at exploiting vulnerabilities in VMware ESXi running on enterprise servers. Black Basta ransomware is written in C++, can target both Windows and Linux systems, encrypts data with ChaCha20, and then the encryption key is encrypted with RSA-4096 for rapid encryption of the targeted network. In some cases, Black Basta leverages malware strains like Qakbot and exploits such as PrintNightmare during the infection process. Black Basta also favors abuse of insecure Remote Desktop Protocol (RDP) deployments, one of the leading infection vectors for ransomware.

Targeted Sectors and Double Extortion

Black Basta typically targets manufacturing, transportation, construction and related services, telecommunications, the automotive sector, and healthcare providers. Black Basta also employs a double extortion scheme and maintains an active leaks website where they post exfiltrated data if an organization declines to pay the ransom demand.
