Hi All,
a customer has got hit by a weird ransomware, the file extensions are random 6 letters.
the ID tool couldn't detect what is it.
If anyone knows what this ransomware is would be great.

Did you find any ransom notes and if so, what is the actual name of the note?
Did the cyber-criminals provide an email address to send payment to? If so, what is the email address?

ID Ransomware cannot properly identify the ransomware without a ransom note since there are several different ransomware infections which append a random 4, 5, 6, 7, 8, etc character extension to the end of all affected filenames (i.e. CTB-Locker, Crypt0L0cker, CryptON (Cry9, Cry36, Cry128, Nemesis), Maktub Locker, Alma Locker, Princess Locker, Locked-In, Mischa, Goldeneye, Al-Namrood 2.0, Cerber v4x/v5x and some Xorist variants).

The best way to identify the different ransomwares that use "random character extensions" is the ransom note (including it's name), samples of the encrypted files, any obvious extensions appended to the encrypted files, information related to any email addresses used by the cyber-criminals to request payment and the malware file responsible for the infection. If you have not done so, suggest you try uploading both encrypted files and ransom notes together at ID Ransomware since that provides a more positive match.

Looks to be new. The ransom note uploaded by the user was "How_To_Decrypt_Your_Files.html", and it just has an iframe to another page.

We'll need a sample of the malware to analyze. I've added identification to ID Ransomware as "Skull Ransomware", pointing victims to this topic.
