Rumba Virus Ransomware

Rumba is a destructive software application working as typical ransomware. Michael Gillespie, the widely known malware researcher, very first discovered this new name in the DJVU ransomware family.

Rumba was developed for the sole purpose to encrypt all popular file types. Logically, as soon as the file encryption is effectively achieved, the users are unable to get access to them. Rumba virus includes its own “.rumba” to all the encrypted data. For example, the file “price_list.xls”, as soon as crypted by Rumba, will be titled as “price_list.xls.rumba”. When the encryption is achieved, Rumba puts its own special text file (_readme.txt) into all the folders that keep the encrypted files.

The alert stated by _readme.txt requesting the random os very comparable to the alerts given by other ransomware threats coming from the DJVU family. The caution generally shows that the data has been encrypted and the only option to get access to it is to use a distinct standalone key. Regretfully, this statement is definitely true.

The method to encrypt the files used by Rumba is not completely looked into. Nevertheless, there is no doubt that each computer owner may be provided a special decryption key, which is definitely distinct. It is very difficult to recuperate the data without the proper type in place.

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

message from Rumba virus

One more peculiarity of the Rumba ransomware is that the users are unable to get access to the key. The decrypting key is hosted on a special server under the complete control by the scoundrels who have actually introduced the Rumba ransomware into the world wide web. In order to acquire the key and restore the crucial information, the users are informed to connect with the frauds through email or by telegram and to pay the ransom in the amount of $980.

The message likewise states that individuals need to get in touch with the Rumba authors within 72 hours upon the moment of the data encryption. The alert suggests that by doing so the people will get a 50% discount, therefore, the ransom quantity drops down to $490.

No matter what the amount of the ransom is, we strongly recommend that you do not pay the ransom. There is no warranty that these online criminals will keep their guarantees, so they may not care at all what the victims feel about the encryption, even when the amount of the ransom is received into their accounts. Thus, paying ransom frequently does not result in an effective healing. So, the users might simply lose their money for nothing.

Likewise, we urge you not to call the frauds as they instruct. Do not transfer money into their wallets. There are no applications that could crack the Rumba ransomware or bring back the data at no charge. For that reason, the only right decision is to restore the information from possible backups (if available).
