Mool Virus – Details

Mool is a malicious software working as typical ransomware. Michael Gillespie, the popular virus researcher, first discovered this new name in the DJVU ransomware family.

Mool was developed for the sole function to encrypt all popular file types. Rationally, as quickly as the file encryption is effectively accomplished, the users are not able to get access to them. Mool ransomware adds its own “.mool” to all the encrypted files. For example, the file “price_list.xls”, when crypted by Mool, will be titled as “price_list.xls.mool”. When the file encryption is achieved, Mool puts its own distinct text file (_readme.txt) into all the folders that save the encrypted files.

The alert mentioned by text file requesting for the random os extremely similar to the notifications offered by other ransomware threats belonging to the DJVU family. The caution basically shows that the data has been encrypted and the only option to get access to it is to use an unique standalone key. Regretfully, this statement is absolutely real.

The technique to encrypt the files utilized by Mool is not totally researched. Nevertheless, there is no doubt that each computer system owner might be released an unique decryption key, which is absolutely special. It is extremely tough to recuperate the data without the appropriate key in place.

One more peculiarity of the Mool ransomware is that the users are unable to get access to the key. The decrypting key is hosted on an unique server under the total control by the crooks who have actually launched the Mool virus into the internet. In order to acquire the key and bring back the important data, the users are informed to contact the frauds by means of e-mail or by telegram and to pay the ransom in the amount of $980.

The message also states that individuals ought to contact the Mool authors within 72 hours upon the moment of the data file encryption. The alert suggests that by doing so individuals will get a 50% discount, for that reason, the ransom amount falls to $490.

No matter what the amount of the ransom is, we highly advise that you do not pay the ransom. There is no guarantee that these online scoundrels will keep their promises, so they may not care at all what the victims feel about the file encryption, even when the quantity of the ransom is received into their accounts. Thus, paying ransom often does not result in an effective recovery. So, the users might just lose their money for absolutely nothing.

There are no applications that might break the Mool virus or restore the data at no charge. For that reason, the only right decision is to restore the data from possible backups (if readily available).
