Researchers use Hive ransomware's own encryption algorithm to find master decryption key
Security researchers have managed to use the encryption algorithm used by the Hive ransomware to determine the master key needed to decrypt files for free.
Ordinarily, victims of a Hive ransomware attack would have to pay up to receive their individual decryption key. But a team of researchers from the Department of Financial Information Security, at Korea's Kookmin University, have been able to calculate the master key. This has then been used in what is believed to be the "first successful attempt at decrypting Hive ransomware"
