Ooif Virus – Details

Ooif is a harmful software functioning as common ransomware. Michael Gillespie, the widely known malware researcher, very first discovered this new name in the DJVU ransomware family.

Ooif was created for the sole function to encrypt all popular file types. Rationally, as quickly as the file encryption is successfully achieved, the users are not able to get access to them. Ooif ransomware adds its own “.ooif” to all the encrypted files. For instance, the file “price_list.xls”, as soon as modified by Ooif, will be titled as “price_list.xls.ooif”. Once the encryption is achieved, Ooif puts its own unique text file (_readme.txt) into all the folders that keep the encrypted files.

The message specified by text file asking for the random os very comparable to the notices offered by other ransomware risks coming from the DJVU family. The caution basically shows that the files have been encrypted and the only service to get access to it is to use a special standalone key. Regretfully, this declaration is absolutely real.

The method to encrypt the files used by Ooif is not completely researched. Nevertheless, there is no doubt that each computer system owner may be released an unique decryption key, which is absolutely unique. It is extremely difficult to recuperate the data without the suitable key in place.

“Don’t worry, you can return all your files!”, from _readme.txt message:

message from Ooif virus

One more peculiarity of the Ooif virus is that the users are unable to get access to the key. The decrypting key is hosted on a special server under the total control by the scoundrels who have actually launched the Ooif infection into the internet. In order to acquire the key and restore the crucial information, the users are told to get in touch with the scams through e-mail or by telegram and to pay the ransom in the quantity of $980.

The message likewise says that individuals should call the Ooif authors within 72 hours upon the moment of the information encryption. The alert indicates that by doing so the people will get a 50% discount rate, for that reason, the ransom amount falls 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 scoundrels will keep their promises, so they may not care at all what the victims feel about the file encryption, even when the quantity 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 absolutely nothing.

Likewise, we urge you not to contact the scams as they advise. Do not transfer cash into their wallets. There are no applications that could split the Ooif virus or restore the information for free. For that reason, the only correct decision is to bring back the data from possible backups (if available).
