XTBL (virus-encryptor): how to decipher? Decrypt files after the virus with the extension XTBL

Relatively recently, the Internet has a new pest - the virus-encryptor XTBL. For many users, it has become a real headache. The fact is that in essence it is a program-extortionist, to cope with which is not so easy. But let's see what can be done and what actions to take is highly discouraged.

What is an XTBL virus?

The fact that computer viruses exist does not need to be explained to anyone. Today they can count hundreds of thousands. But one of the most global problems is the recent appearance of an XTBL virus remotely encrypting data on a user's computer terminal.

Quite frankly, many IT-giants such as Kaspersky Lab or ESET were simply not ready for such an epidemic, as they had never faced anything similar before.

Of course, there are a lot of templates in the virus signature database of any corporation developing antivirus software that can track suspicious files and malicious codes, but it turns out that this does not always help.

A similar situation was observed when a well-known and notorious virus called "I Love You" appeared, which simply removed multimedia content from infected computers. The XTBL virus-encryptor operates in a similar manner and is a rather unusual modification of the trojan, combined with extortion of money.

How does the virus get into the system?

As for the penetration into the system, there are several important aspects to note here. The thing is that the virus with the XTBL extension does not show itself as such. Most often the threat comes in the form of a letter to e-mail with attachments of the archive type or type .scr (the standard extension of Windows screensaver files).

Proceeding from this, it is possible to advise, never to separate attachments containing such files, and even if they came from a reliable source. In an extreme case, if there is an established regular anti - virus scanner, before opening the attachment, you just need to check it for threats.

What are the consequences of the virus?

The consequences, alas, are extremely sad. If the user "picked up" such an infection, you need to be extremely attentive.

The virus itself remotely encrypts user files on the computer (most often it applies to photos or music) with renaming of names into a set of letters and digits and applying the extension .xtbl.

But that's not all. After the encryption process is completed, the user is given a system message that the files on the computer have been encrypted. In order to receive the so-called decryptor of files after the XTBL virus, the user is asked to pay a tidy sum (usually around 5000 rubles) and send the code to e-mail addresses such as deshifrovka01@gmail.com, deshifrovka@india.com or decoder1112@gmail.com.

As already understood, this should not be done. As a result, you can just spend money, and in return, not get anything (in fact, it does).

Independent attempts to get rid of the virus

Unfortunately, the technology by which the virus works with the extension of XTBL has not yet been thoroughly studied, so it is not necessary to talk about any active actions.

A misfortune in another: an independent attempt to rename the infected files or change the extension only leads to the fact that all the information will be immediately deleted. For example, you tried to change a file of type 12345уі8758ав9gs5764.xtbl, which used to be a photo. After renaming, of course, the Enter key is pressed to confirm the completion of the operation. The file is immediately deleted, no matter what, not in the "Recycle bin", but from the hard drive without the possibility of recovery. The use of specialized utilities for restoring data also does not guarantee a positive result.

Antivirus utilities

With antiviruses, too, not everything is simple. Today, there is a real threat that the XTBL virus carries . How to decode the data after its impact, yet nobody knows. Note, even Kaspersky Lab's specialists have honestly admitted that they do not currently have an effective means to combat this unexpected threat.

Although in some respects the XTBL virus behaves like a normal Trojan, its effect is very different from the standard one. Even an attempt to find a virus file in the system using a standard scanner or in manual mode, as well as subsequent deletion, only lead to the fact that the virus creates its own copy, disguised as system or user files. In this case, to find it on the computer becomes simply sisyphean labor. Moreover, the virus itself is protected from such interference.

Online scan

As for online decryption, we can say only one thing: at the moment none of the developers have absolutely no means for this. So, if you are offered to use the services of some web resource, you can be sure that this is a complete divorce.

In the priority of creating an antidote for all IT giants, this problem is top priority. But it is not all that bad.

Can I find the decryptor of files after the XTBL virus?

As it is already clear, today there is not any kind of a little working remedy to protect against this virus in nature. However, you can try to prevent the actions that they are committed.

So, for example, if you notice the beginning of the encryption process, you can quickly complete it in the process tree using the standard "Task Manager".

There may be another situation where an XTBL virus already exists on the computer terminal . How do I delete it? You can do this only with the standard antivirus (but by no means manually), although this action is not a guarantee that the user will get rid of this pest.

If nothing helps

In case of emergency, if nothing really helps, you can use Trojan programs such as Rescue Disc with antivirus software. It's not about deciphering now. At least at least to remove the XTBL-virus in another, so to speak, non-released form before the start of Windows can be using utilities such as Rescue Disc.

You can remove the pest itself. But if it concerns the consequences of the Trojan's influence, alas, nothing can be done so far. Apparently, XTBL-virus refers to the new generation of pests, for which the medicine has not yet been created, although all efforts are aimed precisely at this.

According to the latest information, the developers of Kaspersky Lab's anti-virus software stated that in the near future a means of combating the newly appeared computer pest will be found. Well, ordinary users can only wait and hope that the new drug will be most effective.

Conclusion

Finally, it should be said that, unlike standard encryption methods, this virus does not use algorithms such as AES. That is why deciphering the data after the exposure of the virus proves to be just as difficult task as during the Second World War the reports of the German Navy using the Enigma encryption technology.

But do not despair. It seems that in the near future a solution to this problem will be found. The main thing here is not to panic, not to shut down the computer and not to rename files. It is better to wait for the official release of the antivirus solution, otherwise everything can be spoiled.
