Cuba Ransomware is a file-encrypting version of a ransomware infection that can attack computers without showing visible symptoms. The ultimate goal of Cuba Ransomware is to render a list of user files inaccessible so that it can ask the owners for ransom.
Basically, the way this infection operates revolves around a classic blackmail scheme where the files of the victims are held hostage in exchange for some money. Typically, Cuba Ransomware targets commonly used files that are considered of great value such as documents, databases, archives, images, videos, etc. so that once they become encrypted with its secret algorithm, the victims won’t be able to access them with any software unless they apply a special decryption key. This decryption key is precisely what the hackers behind the ransomware virus ask a ransom for and they promise to send it only to those users who agree to fulfill all their demands.
However, it is still questionable whether they will actually send you a key once you have paid them. It would certainly not be unexpected for the hackers to disappear with the money without providing you with a key. After all, the moment they get what they want, they would be least bothered to deal with you and your encrypted files. Moreover, even if they send you something in exchange for your money, there is no guarantee that this will be precisely the key that will successfully decrypt your files.
In this line of thinking, trying to resolve the ransomware problem by means of alternative actions is a much better idea. In fact, it is essential to remove Cuba Ransomware from your computer if you want to be able to use it and potentially recover some of your files on it. Otherwise, if the file-encrypting virus is present in the system, it will continue to encrypt any new file that you create or manage to restore. That’s why, at the end of this article, we have published a detailed removal guide to help you locate and eliminate the ransomware in a quick and effective manner. We have also included as section with free method for file recovery which you can try out.
The Cuba Ransomware virus
The Cuba Ransomware virus is a piece of malware of the ransomware type that can operate under the radar of most antivirus programs. The cryptography used by the Cuba Ransomware virus is not harmful and thus antivirus programs typically don’t do anything to disable it or notify you about the encryption process.
In addition, some more advanced versions of ransomware can even disable your antivirus program to ensure it won’t interfere with their file encrypting process. This, along with the complexity of the encryption code, has greatly helped make ransomware the most dangerous type of malware. That’s why the best way to stay protected is to rely on prevention particularly by keeping away from possible transmitters of such infections and sketchy web content such as spam messages, fake online advertisements or cracked software installers. What is even more important, though, is to create backups of your data on a remote disk or cloud server so that you never have to experience data loss or restricted access.
The Cuba Ransomware file extension
The Cuba Ransomware file extension is an odd suffix that ensures the encrypted files cannot be recognized by any software. The Cuba Ransomware file extension replaces the original file extension and is attached at the end of each encrypted file name.
|Danger Level||High (Ransomware is by far the worst threat you can encounter)|
|Symptoms||Very few and unnoticeable ones before the ransom notification comes up.|
|Distribution Method||From fake ads and fake system requests to spam emails and contagious web pages.|
|Data Recovery Tool||Not Available|
Some threats reinstall themselves if you don't delete their core files. We recommend downloading SpyHunter to remove harmful programs for you. This may save you hours and ensure you don't harm your system by deleting the wrong files.
Remove Cuba Ransomware
Some of the steps will likely require you to exit the page. Bookmark it for later reference.
Reboot in Safe Mode (use this guide if you don’t know how to do it).
WARNING! READ CAREFULLY BEFORE PROCEEDING!
Press CTRL + SHIFT + ESC at the same time and go to the Processes Tab. Try to determine which processes are dangerous.
Right click on each of them and select Open File Location. Then scan the files with our free online virus scanner:
After you open their folder, end the processes that are infected, then delete their folders.
Note: If you are sure something is part of the infection – delete it, even if the scanner doesn’t flag it. No anti-virus program can detect all infections.
Hold the Start Key and R – copy + paste the following and click OK:
A new file will open. If you are hacked, there will be a bunch of other IPs connected to you at the bottom. Look at the image below:
If there are suspicious IPs below “Localhost” – write to us in the comments.
Type msconfig in the search field and hit enter. A window will pop-up:
Go in Startup —> Uncheck entries that have “Unknown” as Manufacturer.
- Please note that ransomware may even include a fake Manufacturer name to its process. Make sure you check out every process here is legitimate.
Type Regedit in the windows search field and press Enter. Once inside, press CTRL and F together and type the virus’s Name.
Search for the ransomware in your registries and delete the entries. Be extremely careful – you can damage your system if you delete entries not related to the ransomware.
Type each of the following in the Windows Search Field:
Delete everything in Temp. The rest just check out for anything recently added. Remember to leave us a comment if you run into any trouble!
