Lapoi Virus Removal Guide (+Decrypt .lapoi files) – DJVU Ransomware

Lapoi Virus – Details

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

The message given by Lapoi text file asking for the ransom is absolutely the same as the statements given by other ransomware virus representatives coming from the DJVU clan. It literally points out that the information is encrypted which the only way to bring back it is to use a an unique decryption key. Unfortunately, this is absolutely true. The type of cryptography mechanism applied by Lapoi is still not appropriately examined. Still, it is absolutely specific that each victim might be given the specific decryption key, which is completely unique. It is difficult to restore the files without the key available.

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

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

Another trick of Lapoi is that the victims cannot get to the key. The key is kept on a specific server run by the frauds related to Lapoi ransomware. To get the key and recover the important info people need to pay the ransom, which amounts to $980. To get the payment information users are instructed to contact the frauds through e-mail or telegram. The alert likewise suggests that the users require to contact the Lapoi developers within 72 hours after the encryption occurred. The message says that doing so users will get a 50% discount, so the ransom amount will fall to $490.

Nonetheless, regardless of the requested amount, people should keep away from paying the virus. Cyber frauds are unfair, so they tend to completely disregard what their victims feel about the problem, even when the payment reaches their pockets. This is why paying the ransom generally does not give any positive result and people simply waste their money for nothing.

We highly advise 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 Lapoi ransomware and to recover the information data for free. Thus, the just right decision is to recover the lost information from the available backup.
