Oovb was created for the sole function to encrypt all popular file types. Rationally, as soon as the file encryption is successfully achieved, the users are not able to get access to them. Oovb virus adds its own “.oovb” to all the encrypted files. For instance, the file “price_list.xls”, when crypted by Oovb, will be entitled as “price_list.xls.oovb”. Once the file encryption is accomplished, Oovb puts its own distinct text document (_readme.txt) into all the folders that store the encrypted files.
The message stated by _readme.txt requesting the random os very comparable to the notices offered by other ransomware hazards belonging to the DJVU family. The warning basically shows that the files have been secured and the only solution to get access to it is to use an unique standalone key. Regretfully, this statement is definitely true.
The method to secure the files used by Oovb is not entirely researched. Nevertheless, there is no doubt that each computer owner may be issued an unique decryption key, which is absolutely distinct. It is extremely hard to recuperate the information without the appropriate key in place.
“Don’t worry, you can return all your files!”, from text file message:
One more peculiarity of the Oovb ransomware is that the users are not able 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 Oovb virus into the internet. In order to acquire the key and restore the crucial information, the users are informed to get in touch with the scams through e-mail or by telegram and to pay the ransom in the amount of $980.
The message also states that individuals ought to call the Oovb authors within 72 hours upon the minute of the data encryption. The alert suggests that by doing so the people will get a 50% discount, for that reason, the ransom amount falls to $490.
