Researchers have exploited a weakness in a particular strain of the Black Basta ransomware to release a decryptor for the malware, but it doesn’t recover all of the files encrypted by the prolific cybercriminal gang.
Security research and consulting firm SRLabs released the tool —appropriately named Black Basta Buster — which exploits a vulnerability in the encryption algorithm of a Black Basta ransomware strain used by the group around April last year. However, there are some limitations on whether a file is fully or partially recoverable based on plaintext requirements and size, the researchers noted.
