Miia – Ransomware
Miia is a harmful software application functioning as typical ransomware. Michael Gillespie, the popular virus researcher, very first discovered this new name in the DJVU ransomware family.
Miia was created for the sole purpose to encrypt all popular file types. Realistically, as quickly as the file encryption is successfully achieved, the users are not able to get access to them. Miia virus adds its own “.miia” to all the encrypted data. For example, the file “price_list.xls”, when crypted by Miia, will be entitled as “price_list.xls.miia”. As soon as the encryption is accomplished, Miia puts its own unique text document (_readme.txt) into all the folders that keep the encrypted files.
The alert specified by text file asking for the random os very similar to the notifications provided by other ransomware threats belonging to the DJVU family. The caution generally shows that the files have been encrypted and the only service to get access to it is to use a distinct standalone key. Regretfully, this statement is absolutely real.
The technique to encrypt the files used by Miia is not totally researched. Nevertheless, there is no doubt that each computer system owner might be released an unique decryption key, which is definitely unique. It is exceptionally difficult to recover the information without the suitable type in location.
“Don’t worry, you can return all your files!”, from _readme.txt message:
One more peculiarity of the Miia ransomware is that the users are not able to get access to the key. The decrypting key is hosted on a special server under the total control by the crooks who have released the Miia infection into the world wide web. In order to obtain the key and bring back the essential data, the users are told to connect with the frauds via email or by telegram and to pay the ransom in the quantity of $980.
The message likewise says that the people ought to contact the Miia authors within 72 hours upon the moment of the data encryption. The alert indicates that by doing so individuals will obtain a 50% discount rate, for that reason, the ransom amount drops down to $490.
