Trend Micro researchers are currently looking into samples of a new variant of the hard drive-locking ransomware family, HDDCryptor. Early in September, researchers found a HDDCryptor (detected by Trend Micro as RANSOM_HDDCRYPTOR.A) variant exhibiting unique routines.
While the new variant (detected by Trend Micro as RANSOM_HDDCRYPTOR.F) shares a number of similar characteristics with its predecessor, initial analysis show that this version differs in how it was packed. As with the first version of HDDCryptor, this variant drops similar components, but in a different folder, %systemroot%\Users\ABCD. On system reboot, the file encryption of the infected machine’s disk drive ensues, before replacing the screen with a note that informs the victim that the computer has been compromised.
Further analysis of discovered samples is still ongoing to see whether this is an upgraded variant or one that is simply based on the earlier version of the said ransomware family.
