Xcmb Virus

Xcmb

Xcmb is a ransomware cryptovirus designed to apply encryption to user files and to demand a ransom payment in order to decrypt them. Xcmb typically encrypts documents, audio and video files, databases, and images and holds them hostage until the victim transfers the required money.

The Xcmb Virus ransom note

Xcmb is undoubtedly one of the most malicious variants of ransomware that could be encountered online. This malware is programmed to secretly encrypt your data and then display a ransom note on your screen asking for a certain amount of money. You can find more information about this awful program in the paragraphs that you are about to read but what you are probably most interested in is how to remove it and how to recover your encrypted files. That’s why, at the end of this article, we have published a free removal guide with ransomware-removal and file-recovery instructions that may possibly help you deal with Xcmb.

The Xcmb virus

The Xcmb virus is malicious software created for blackmail purposes. The Xcmb virus uses file encryption to restrict access to valuable user files and then demands a ransom payment from its victims in order to restore access to the encrypted files.

Xcmb Ransomware is a really dangerous infection that can pose a challenge even for professionals in the field of cyber security. This being said, there is no guarantee that the encrypted data can be recovered unless the victims possess a full data backup copy.

This is how a standard Ransomware-based virus usually operates:

  1. The first step is to infect the device. This can happen in many ways but most commonly when users interact with a piece of web content that contains the ransomware infection. There may be many potential carriers of such malware that web users can come across: from program bundles and infected websites, fake ads, torrents, or spam email messages to shareware and malicious links. That’s why it really matters that you are careful when you browse the web and click only on reliable materials.
  2. After the ransomware enters your system, it will attempt to identify which files are most valuable to you and will encrypt them all with complex code.
  3. At the end of the attack, a ransom notification will be displayed on your screen. This notification will require a money transfer to a given cryptowallet in case that you want to regain access to the encrypted files.

The Xcmb file encryption

The Xcmb file encryption is a malicious process that the cyber criminals behind the Xcmb ransomware use to prevent users from opening and using their information. The Xcmb file encryption process runs in the background of the system and is typically not detected by most security programs.

The Ransomware-based Program’s intentions are clear – money extortion. However, you can never be sure about the intentions of the hackers who control it.

Don’t waste your money to sponsor criminals who target naive people. In case you don’t know where to start, our Removal Guide here can prove to be quite useful.

Many harmful processes begin running in the background as soon as ransomware infection occurs. Because of this, the next step is to open the Processes Tab in Task Manager and stop any processes you feel are linked to the activity of Xcmb.

Pressing CTRL, SHIFT, and ESC simultaneously launches the Task Manager. If you think that a specific process is dangerous or connected to the ransomware, all you have to do is right-click on it in the Processes tab and select Open File Location.

    You can end a process by right-clicking on it In the Processes tab, and choosing the option “End Process“.

    Step3

    The Hosts file may suffer unauthorized alternations if your machine has been infected by Xcmb. Therefore, we recommend that you open it and look for changes under Localhost in the text to make sure everything is okay.

    For this, you’ll need to press the Windows Key and R, and type the following command into the Run box that will appear on the screen:

    notepad %windir%/system32/Drivers/etc/hosts

    When you click OK in the Run window, you should see a file that looks like this:

    hosts_opt (1)

    As seen in the example screenshot above, if you identify any IP addresses associated with virus creators, please notify us by leaving a comment below this post, so that we can have a look and give you advice on what to do.

    Step4

    To remove parasite on your own, you may have to meddle with system files and registries. If you were to do this, you need to be extremely careful, because you may damage your system.

    If you want to avoid the risk, we recommend downloading SpyHunter
    a professional malware removal tool.

    In many ransomware attacks, dangerous files are added to your computer’s Registry in order to modify your system. No matter whether you’ve been infected with Xcmb or any other virus, you should search the Registry for malicious entries and remove everything you think is linked to the infection. 

    To do that, simply type Regedit into the Windows search bar and press Enter to open the Registry Editor. Then, press CTRL and F together and type the ransomware’s name into the Editor’s Find dialog box. After that, click on the Find Next button in order to figure out whether there are any entries with that name and start a search. Anything that is found in the search results most likely should be deleted as it might be linked to the infection.

    Attention! An inexperienced user who doesn’t know which files are dangerous and need to be removed may do significant damage to the system if they make registry changes. Therefore, a professional removal program should be used to remove any dangers and malicious files from the system and the registry.

    The Registry may be closed after you are certain that it is clean. 

    Next, using the Windows Search Field, type each of the following locations (including the percent symbol) and open them to see if any new items have been added to them:

    1. %AppData%
    2. %LocalAppData%
    3. %ProgramData%
    4. %WinDir%
    5. %Temp%

    Just keep an eye out for any new files in the four locations listed above. No: 5 is the Temp folder. Once you open it, select and remove everything, including the temporary files that the ransomware may have created.

    Step5

    How to Decrypt Xcmb files

    Victims of different Ransomware variants may need the use of different set of tools and methods to decode encrypted data. Therefore, before you dig into the instructions below, make sure that you know the exact variant of ransomware that has encrypted your files. To figure this out, look at the file extensions that have been added to the encrypted files. 

    New Djvu Ransomware

    Users are now being actively targeted by the latest Djvu ransomware variant, which is known as STOP Djvu. This variant adds the suffix .Xcmb at the end of every file that it encodes. Currently, STOP Djvu encoded files can only be decrypted if they were encrypted with an offline key. If you need assistance decrypting your data, we recommend you try the decyptor tool available on this link:
