BlackBasta Ransomware Detection (YARA)

This YARA rule detects the BlackBasta ransomware by identifying specific byte patterns within executable files. The patterns correspond to various functionalities commonly found in ransomware, such as enumerating files, interacting with system volumes, dropping ransom notes, excluding certain files from encryption, and the encryption routines themselves. The rule looks for two main variants of these functionalities, indicating different versions or implementations of BlackBasta.
