How To Remove Cuba ransomware And Recover Infected Data

Simple Steps To Delete Cuba ransomware From Computer

Cuba ransomware is a kind of deadly crypto-virus that encrypts users’ crucial files and data stored inside their PCs and then extorts huge amount of ransom money in exchange of the decryption tool. This hazardous file-encoding malware uses a strong RSA-2048 encryption algorithm to lock your essential files such as images, videos, audios, documents, presentations etc. and makes them totally useless. You can easily determine the infected files as this hazardous threat appends “.cuba” extension with the name of each of them. After getting encoded by this dangerous parasite, all your crucial files become completely inaccessible and can be only opened by using a decryption software that is kept on attackers’ server.

Following successful encryption, Cuba ransomware drops a ransom note titled “!!FAQ for Decryption!!.txt” on the desktop and informs you about the unkind situation. It also includes an email address in order yo contact the hackers and get further details. Crook state that to get the required decryptor and open the locked data, you must pay the attackers a sum of ransom. The ransom amount is not listed in the text file but it depends on how quickly you contact the criminals. At the end of the note, you are warned not to rename the files or try to open them via third-party software otherwise it may cause permanent data loss.

Text Presented in The Ransom Note:

Good day. All your files are encrypted. For decryption contact us.
Write here [email protected] [ mailto:[email protected] ]
We also inform that your databases, ftp server and file server were downloaded by us to our servers.

* Do not rename encrypted files.
* Do not try to decrypt your data using third party software,
it may cause permanent data loss.

Should You pay The Ransom?

It is true that files locked by Cuba ransomware can’t be opened without using the decryption tool but still, we highly advise to not deal with the criminals. According to the reports, such types of hackers generally ignore the victimized users after taking the ransom and cause them to lose both files as well as money. It has been also seen that at various occasions crooks provide rogue software to the victims in the name of decryption tool which only harms the device badly upon getting installed. And so, never trust on the criminals under any circumstance and try to delete Cuba ransomware from the PC as soon as possible.

How To Recover The Infected Data?

This dangerous crypto-malware deletes the Shadow Volume Copies of your encoded files by running the vssadmin.exe delete shadows /all /Quiet command via PowerShell service that disables the automatic data recovery feature of the compromised device. However, if you have a backup made on any external drive, you can easily retrieve the infected data at some amount.
