BlackByte blends tried-and-true tradecraft with newly disclosed vulnerabilities to support ongoing attacks
Aug. 28, 2024, 2:35 p.m.
Description
The BlackByte ransomware group continues leveraging established tactics and vulnerable drivers to bypass security controls, while also incorporating newly disclosed vulnerabilities and using stolen credentials for propagation. A new iteration of their encryptor appends the 'blackbytent_h' extension to encrypted files, drops four vulnerable drivers, and employs Active Directory credentials for self-propagation. The group appears more active than its data leak site suggests, rapidly adapting its techniques.
