Black Basta v2

Description
For more information, please see the entry on Black Basta.
As you can probably guess, Black Basta v2 is the second iteration of the Black Basta ransomware. It appeared sometime in November 2022. It could be argued that it's the third or fourth considering that the first known samples were titled "no_name_software" and were the first samples created by the group based on compilation times and debugging behaviors upon execution. They also made a Linux encryptor for VMware ESXi servers, which we found a handful of and listed among the samples in the Black Basta entry. The Black Basta v2 ransomware targets Windows systems and has a few different characteristics than its predecessor.
The most obvious difference is the name of the ransom note. Instead of "readme.txt," the group changed the ransom note name to "instructions_read_me.txt." They also altered the encryption mechanism to encrypt files. Initially, it was a combination of ChaCha20 and RSA-4096. This time, it uses a different combination - XChaCha20 and the NIST P-521 elliptical curve algorithm, respectively. Another technical difference is the file extension used. Black Basta used the stereotypical self-named file extension on encrypted files - ".basta." Now, the file extension is a random 9-letter alphanumeric sequence.
Otherwise, most of the other details about Black Basta v2 are similar to Black Basta, including the same extortion page, Ransomware-as-a-Service approach, and threat actors such as QBot to begin their breaches. However, the authors implemented increased command-line flexibility, including variability in the number of threads used, mutex creation, and path specification.
