Lokf – Ransomware
Lokf is a harmful software application working as typical ransomware. Michael Gillespie, the widely known virus researcher, first found this new name in the DJVU ransomware family.
Lokf was created for the sole purpose to encrypt all popular file types. Rationally, as soon as the encryption is successfully achieved, the users are unable to get access to them. Lokf virus adds its own “.lokf” to all the encrypted files. For instance, the file “price_list.xls”, when crypted by Lokf, will be titled as “price_list.xls.lokf”. As soon as the encryption is accomplished, Lokf puts its own special text document (_readme.txt) into all the folders that save the encrypted files.
The alert mentioned by text file asking for the random os really comparable to the notices offered by other ransomware risks belonging to the DJVU family. The warning basically indicates that the information has been secured and the only solution to get access to it is to use an unique standalone key. Regretfully, this statement is definitely real.
The approach to encrypt the files utilized by Lokf is not completely researched. Nevertheless, there is no doubt that each computer owner might be released a special decryption key, which is absolutely unique. It is very tough to recover the information without the appropriate type in place.
“Don’t worry, you can return all your files!”, from text file message:
One more peculiarity of the Lokf virus 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 launched the Lokf ransomware into the internet. In order to obtain the key and restore the essential data, the users are told to contact the frauds via email or by telegram and to pay the ransom in the amount of $980.
The message likewise says that the people should contact the Lokf authors within 72 hours upon the moment of the data file encryption. The alert suggests that by doing so the people will get a 50% discount rate, therefore, the ransom quantity falls to $490.
No matter what the amount of the ransom is, we highly recommend that you do not pay the ransom. There is no guarantee that these online scoundrels will keep their guarantees, so they might not care at all what the victims feel about the encryption, even when the amount of the ransom is received into their accounts. Hence, paying ransom typically does not lead to a successful recovery. So, the users may merely lose their money for absolutely nothing.
Similarly, we urge you not to call the frauds as they advise. Do not move money into their wallets. There are no applications that could crack the Lokf ransomware or restore the data for free. For that reason, the only appropriate decision is to bring back the information from possible backups (if offered).

All these infections use the similar algorithm to create the particular key for successful files decryption.
Unless the Lokf ransomware is still under the development procedure or has got some hidden bugs, it is not possible to bring back the data by hand. Therefore, the only working solution to prevent the loss of your essential information is to regularly preserve updated backups of all your crucial documents.

For example, you might save it on the USB Flash Drive, or some external disk drive, or by using the cloud data storage services.
