Maas Virus – Details
Maas is a harmful software working as typical ransomware. Michael Gillespie, the popular virus researcher, first found this new name in the DJVU ransomware family.
Maas was developed for the sole purpose to encrypt all popular file types. Logically, as quickly as the file encryption is successfully accomplished, the users are unable to get access to them. Maas virus adds its own “.maas” to all the encrypted files. For example, the file “price_list.xls”, when crypted by Maas, will be entitled as “price_list.xls.maas”. Once the file encryption is achieved, Maas puts its own special text file (_readme.txt) into all the folders that store the encrypted files.
The alert stated by document asking for the random os very similar to the notifications given by other ransomware dangers belonging to the DJVU family. The warning basically shows that the data has been encrypted and the only service to get access to it is to use a distinct standalone key. Regretfully, this declaration is definitely true.
The technique to encrypt the files used by Maas is not completely investigated. Nevertheless, there is no doubt that each computer system owner might be issued an unique decryption key, which is absolutely distinct. It is extremely tough to recuperate the information without the proper key in location.
“Don’t worry, you can return all your files!”, from text file message:
One more peculiarity of the Maas virus 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 criminals who have released the Maas ransomware into the internet. In order to acquire the key and bring back the crucial data, the users are told to get in touch with the frauds by means of email or by telegram and to pay the ransom in the quantity of $980.
The message likewise says that the people must call the Maas authors within 72 hours upon the minute of the data encryption. The alert indicates that by doing so individuals will obtain a 50% discount, therefore, the ransom quantity falls to $490.
No matter what the quantity 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 guarantees, so they might not care at all what the victims feel about the file encryption, even when the amount of the ransom is received into their accounts.
