The Rise of Black Basta Ransomware Group


The Black Basta ransomware group has attacked Doyon, compromising 700GB of data. Doyon Drilling operates on the North Slope of Alaska with nine oil and gas land drilling rigs specially designed to drill oil wells in extreme conditions. The company currently has over 300 employees, with the main office located in Anchorage, Alaska.

Emergence of 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.

Modus Operandi

Black Basta 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 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

Black Basta continues to evolve its RaaS platform with ransomware payloads that can infect systems running both Windows and Linux. The 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.

Targeted Sectors

Black Basta typically targets manufacturing, transportation, construction, and related services, as well as telecommunications, the automotive sector, and healthcare providers. The group also favors abuse of insecure Remote Desktop Protocol (RDP) deployments, one of the leading infection vectors for ransomware.

Double Extortion Scheme

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.

Recent Ransomware Attacks

The Recent Ransomware Attacks (RRA) site acts as a watchtower, providing you with near real-time ransomware tracking of attacks, groups and their victims. Given threat actors’ overarching, lucrative success so far, ransomware attacks have become the most ubiquitous, and financially and informationally impactful cyber threat to businesses and organizations today.

The site’s data is generated based on hosting choices of real-world threat actors, and a handful of other trackers. While sanitization efforts have been taken, we cannot guarantee 100% accuracy of the data. Attack updates will be made as source data is reported by reputable sources. By viewing, accessing, or using RRA you acknowledge you are doing so at your own risk.
