Masodas – General Info

Masodas is a malicious software application functioning as common ransomware. Michael Gillespie, the well-known malware researcher, very first found this new name in the DJVU ransomware family.

Masodas was created for the sole function to encrypt all popular file types. Rationally, as soon as the encryption is effectively achieved, the users are not able to get access to them. Masodas virus adds its own “.masodas” to all the encrypted data. For example, the file “price_list.xls”, once crypted by Masodas, will be entitled as “price_list.xls.masodas”. Once the encryption is achieved, Masodas puts its own special text document (_readme.txt) into all the folders that store the encrypted files.

The message stated by _readme.txt requesting for the random os extremely similar to the notifications offered by other ransomware risks coming from the DJVU family. The warning essentially indicates that the files have been encrypted and the only option to get access to it is to use a distinct standalone key. Regretfully, this statement is definitely real.

The technique to encrypt the files utilized by Masodas is not entirely investigated. However, there is no doubt that each computer owner may be provided a special decryption key, which is absolutely special. It is extremely difficult to recuperate the data without the proper key in location.

“Don’t worry, you can return all your files!”, from text file message:

One more peculiarity of the Masodas ransomware is that the users are unable to get access to the key. The decrypting key is hosted on an unique server under the complete control by the criminals who have actually introduced the Masodas virus into the world wide web. In order to get the key and bring back the essential data, the users are informed to contact the frauds by means of email or by telegram and to pay the ransom in the quantity of $980.

The message also says that individuals ought to contact the Masodas authors within 72 hours upon the minute of the information file encryption. The alert indicates that by doing so the people will get a 50% discount rate, for that reason, the ransom amount drops down to $490.

There is no assurance that these online criminals will keep their pledges, so they might not care at all what the victims feel about the file encryption, even when the quantity of the ransom is received into their accounts.
