XTBL how to decipher? XTBL virus-encryptor

Viruses are an integral part of the life of a modern computer user. Especially suffer from them users of the Windows operating system from Microsoft. Of course, there are viruses for other operating systems, but they are much smaller. Systems such as MacOS and Linux are more secure from intrusion from outside and loss of user files. More recently, a new virus-encryptor XTBL appeared on the Internet . How can I decrypt lost data and protect myself from this virus in general ? This question will be discussed below.

What is the XTBL virus?

XTBL is a virus that uses an encryption code of 1024 bits. Once on the computer, it remotely encrypts the user's files. Basically amazing music and photos. After the end of the encryption process , the files get the extension ".xtbl", and it is no longer possible to open them. It's useless to try to rename files with the extension ".xtbl". If such an attempt is made, they will be immediately removed by the virus. And forever.

The user receives a system message stating that his data is encrypted and the offer to read the "Readme.txt" file for more information. And this file contains instructions for decryption. And it says that the user must send a certain amount to the specified address. And in return he will receive a key and an XTBL decoder. Although usually nothing is sent.

Here is a brief description of this virus. Agree, it's pretty unpleasant to pay a large amount of money for what. At the moment, XTBL is the most dangerous virus, since free antiviruses can not determine it. And such giants as NOD or Kaspersky, can detect it only if it is not modified.

Ways of infection with the virus

There are several ways to "hook up" XTBL. They are especially relevant for Windows users. Because the virus is usually hidden in executable files with the extensions ".exe", ".scr" or ".bat". Users of Linux or MacOS live much easier, because these extensions are simply not supported on their OS. So, the main ways to infect a virus:

• By e-mail (some file attached to the letter).
• Through programs of hacking licensed products. The so-called "crack".
• When unpacking downloaded from an unreliable source archive.

These are the main ways of infection. Remember, if in the email you sent you see an attached document of the type "Report.doc.exe", in any case do not open it. There may be an XTBL file of the virus. Well, by itself, do not even go to dubious sites and download pirated software.

How the XTBL virus works

The algorithm of the virus is based on the remote encryption of user data . After penetration, the virus secretly encrypts individual files. At the very beginning of the process, it can still be stopped. Just kill the process in the Windows Task Manager. After that, of course, you need to clean the system with special programs, but not any antivirus will do. To remove you need some powerful product such as Kaspersky.

The XTBL virus uses the encoding of 1024 bits. The most deciphered result of his malicious work is unreal. The selection of the decryption combination will take about thirty years. When you try to rename the encrypted XTBL file to some "normal" format, the file is completely deleted. And not at all in the basket and without any warning. Therefore, if you became his victim, you should not immediately conduct any manipulations with encrypted information.

After successfully encrypting files, the virus will self-destruct. That's why it is then impossible to detect. And to you "as a gift" there is a format ".xtbl" which can not be opened by any nowadays existing programs. Unlike similar viruses, XTBL uses an "advanced" encoding algorithm. In addition, apparently, the key for decryption is generated using the computer name. That's why standard programs for decryption do not help. Even antivirus giants do not have an algorithm for decoding the consequences of XTBL work. Simply put, if your files are encrypted with an XTBL virus, then it's unlikely that anything will help you.

Some modifications of XTBL can also delete OS backup points. So you can not use the function "Previous versions of files".

Methods for decrypting files

Unfortunately, there are no concrete effective ways to eliminate the consequences of the virus. A normal and stable XTBL decoder can not be found, it exists in nature. Moreover, the virus is constantly being modified, and in some cases it can even be difficult to determine.

The only thing that can be done after a successful virus removal is to contact the specialists in the information recovery. But here again, no one will give a one hundred percent guarantee of the return of all your files. Usually this method helps only 70% of users. But this is also a good result.

If there are backups, then there should not be any problems. It is enough to "cure" XTBL One of the most powerful antivirus software. After that, you can start restoring files from the backup. If there is no copy, then you can use the standard Windows feature "Previous versions of files". Of course, there is very little chance of success. Few manage to overcome the XTBL virus. How to decipher his "creativity" is still not really known. But do not lose hope that once will be developed means of deciphering.

How to avoid such unfortunate consequences

Not a single antivirus will give a 100% guarantee of protection against malware. Even the coolest. To prevent the consequences of the virus, you need to regularly back up files (backups). The main thing is to not be too late. If you try to copy the XTBL file, the virus immediately removes it.

Backups are best created in specialized programs, because they use a file format that no virus can infect. In addition, do not store it on the computer. It is advisable to write to disk to avoid possible infection.

Methods of protection and treatment

To protect against this virus, it is recommended to use software products that have already proven themselves in the anti-virus market. For example, Kaspersky, NOD 32 or Dr.Web. Web. Of course, they are paid. However, in the presence of a paid license, these companies can not only help with protection. If your files are encrypted with an XTBL virus, they can try to create a special decryptor specifically for you. Definitely, such a service is worth the money spent.

To cure and remove the XTBL virus, the first thing to do is to boot the operating system into safe mode. All subsequent operations should be performed only in it. After that, you should run the antivirus and choose a "deep" scan. The process, of course, will last for a couple of hours at least, but there is hope for finding and removing the virus. Files with the extension ".xtbl" are not considered by the antivirus as a threat. So they will not go anywhere, and eventually you will be able to proceed to the attempts of decryption.

Other viruses from the same "family"

The XTBL virus is not the only one. Although the most "cool". Now there is a huge number of extortion programs. All sorts of "lockers" try to shake money out of ordinary users by hook or by crook.

Some time ago, a "sms locker" was also popular, also encrypting user files. But unlike XTBL, its purpose was system files. On one "fine" day, when the computer was switched on and the OS was loaded, the user saw a system message about the blocking and instructions for sending money. The computer did not turn on. But with these viruses everything was much easier. Helped banal reinstallation of the OS in contrast to XTBL. How to decrypt files, it was not necessary to think.

Conclusion

As you can see, there are a lot of viruses in the computer world. Some do not bring any appreciable harm and look absolutely harmless. But some "monsters" can make "sweat", raking up the consequences of their work. The main thing is not to forget about precautions and perform simple infection prevention.

Well, if you "pick up" some light virus. And if suddenly something serious like XTBL? How to decipher his "doodle" - we disassembled, of course, little chance, but they are!
