Voom – General Info
Voom is a malicious software functioning as typical ransomware. Michael Gillespie, the widely known malware researcher, very first found this new name in the DJVU ransomware family.
Voom was developed for the sole purpose to encrypt all popular file types. Rationally, as quickly as the encryption is successfully achieved, the users are not able to get access to them. Voom virus includes its own “.voom” to all the encrypted files. For example, the file “price_list.xls”, as soon as modified by Voom, will be titled as “price_list.xls.voom”. Once the encryption is achieved, Voom puts its own distinct text file (_readme.txt) into all the folders that save the encrypted files.
The message mentioned by text file requesting for the random os very similar to the notifications provided by other ransomware hazards belonging to the DJVU family. The caution generally shows that the files have been secured and the only service to get access to it is to use an unique standalone key. Regretfully, this statement is absolutely true.
The method to encrypt the files used by Voom is not completely looked into. However, there is no doubt that each computer system owner might be provided an unique decryption key, which is definitely distinct. It is extremely tough to recuperate the data without the appropriate key in location.
“Don’t worry, you can return all your files!”, from _readme.txt message:
One more peculiarity of the Voom infection is that the users are not able to get access to the key. The decrypting key is hosted on a special server under the complete control by the crooks who have actually introduced the Voom ransomware into the web. In order to get the key and bring back the important data, the users are informed to connect with the frauds via e-mail or by telegram and to pay the ransom in the amount of $980.
The message likewise states that the people must get in touch with the Voom authors within 72 hours upon the moment of the data file encryption. The alert indicates that by doing so the people will acquire a 50% discount, therefore, the ransom amount drops down to $490.
