The .Lapoi Virus in Depth

Lapoi Virus

The .Lapoi Virus will show you this message, which contains instructions for paying the ransom.

If you have found this page because a Ransomware named Lapoi has secretly encrypted your files and you have been seeking help against it, stay with us – you may find useful information in this post. Here, you will find a detailed Removal Guide that is created with the sole idea to help you remove this nasty malware from your computer and save whatever files could be saved from its grasp. Before you go directly to the instructions, however, let us tell you a few more words about the specifics of Lapoi, and about the methods you can use to protect yourself from such infections in the future.

Ransomware, generally, is software that is designed to restrict the access to a given computer or its files and, thereby, be able to request a ransom in exchange for their liberation. The representatives of the Ransomware subcategory that encrypts files are also known as a cryptoviruses, while the ones that blocks access to the computer’s screen is usually called a screen locker. Lapoi belongs to the cryptovirus type ( DarusTocueGusau) and is considered more challenging to deal with, as the encryption code applied by it can be very difficult to reverse. This type of malware is usually distributed through different files that could be attached to malicious emails, spam messages, torrents and software installers, as well as via illegal webpages or sites that have been previously attacked and compromised.

In many cases, the Ransomware is presented as a compressed file (usually with the extension ZIP), and upon extracting the files in it, the user may encounter seemingly harmless files such as PDF documents, other text documents, audio or video files or images and so on, that actually carry the infection inside them.

Once the infection sneaks in the system, it immediately starts its encryption process. A key pair, a Public and a Private key, are generated – the public key is used to encrypt the different files of the victim (generally those are DOC, PDF, XLS extensions, images, CAD files and any other file format that is assumed to be important to the user), while the private key, which is supposed to decrypt the files, is stored in the server of the attacker that has control over the Ransomware.

Then a message appears on the screen, and in that message, it is said that the files have been encrypted by Lapoi and that, in order to decrypt them, the victims would have to pay a ransom to the blackmailers. Usually, currency of payment required by the hackers would be one that guarantees their anonymity. This is why BitCoin is oftentimes the preferred currency in which the ransom is demanded. A countdown clock is typically added in the messages (generally 24 or 48 hours), indicating that at the given time, the private key will be destroyed or that the required payment sum would go up.

Is the payment of the ransom that .Lapoi File requires a good idea?

Lapoi Virus

.Lapo Virus Ransomware is from the STOP/ DJVU family, it will encrypt your files with .Lapoi extension.

If the victim agrees to pay the ransom, in theory, they should receive the decryption key for their files as soon as the hackers receive their payment. However, in reality, there is no guarantee that the files will be successfully recovered and that the key will work. Moreover, the Ransomware may also not go away even if you pay. Not to mention that there have already been many cases in which a ransom has been paid, and yet the users who have paid it have not received a working key (or any ky for that matter). Furthermore, different official sites belonging to security agencies are advising against the payment of the ransom, since this action would only be encouraging the further development and use of infections like Lapoi by their creators.
