Lotej Virus Removal Guide (+Decrypt .lotej files) – DJVU Ransomware

Lotej Virus – Details

The Lotej stands for a ransomware-type infection. Initially, it was revealed by Michael Gillespie. The virus comes from the DJVU ransomware family. Lotej was elaborated particularly to encrypt all major file types. Once the file is encrypted people are not able to use them. Lotej adds the “.lotej” extension for each file encrypted by it. For example, the file “myphoto.jpg“, once encrypted by Lotej, will be renamed into “myphoto.jpg.lotej. As quickly as the encryption is finished, Lotej places a special text file (such as “_readme.txt“) into every folder containing the encrypted data.

The message given by Lotej text file requesting the ransom is definitely the like the statements given by other ransomware virus representatives belonging to the DJVU clan. It literally points out that the information is encrypted and that the only way to restore it is to use a a special decryption key. Regretfully, this is absolutely true. The type of cryptography mechanism used by Lotej is still not appropriately examined. Still, it is definitely specific that each victim might be given the specific decryption key, which is totally distinct. It is difficult to restore the files without the key available.

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

Don't worry, you can return all your files! virus

Another trick of Lotej is that the victims cannot gain access to the key. The key is saved on a specific server run by the frauds connected with Lotej ransomware. To get the key and recover the important info people have to pay the ransom, which totals up to $980. To obtain the payment details users are advised to contact the frauds through email or telegram. The alert also shows that the users need to contact the Lotej developers within 72 hours after the files encryption took place. The message says that doing so users will get a 50% discount, so the ransom amount will fall to $490.

However, regardless of the asked for quantity, people need to stay away from paying the ransom virus. Cyber frauds are unfair, so they tend to completely ignore what their victims feel about the problem, even when the payment reaches their pockets. This is why paying the ransom normally does not provide any positive result and people simply lose their money for nothing.

We strongly encourage that you do not contact these crooks and definitely do not transfer money into their accounts. It is said to admit that there are no utilities able to crack Lotej ransomware and to recover the data data free of charge. Thus, the just best decision is to recover the lost information from the available backup.
