What is Cuba Ransomware?

The Cuba Ransomware targets the Windows operating system. It was discovered by Ravi, an American Ransomware hunter. His attacks are carried out through email campaigns.

The emails contain a link to “subscribe” to a service document, the malware is delivered via this macro-loaded Word document, which contains a Hancitor payload, which is downloaded and opened.

Hancitor is a downloader that was first seen in 2014, it delivers macros which is an elaborate command that converts peripheral inputs into commands and actions in Windows.

With these commands it invades and installs into the operating system tools that will open doors to extract data, along with these tools comes Cuba ransomware which when installed compromises Windows systems and takes full control of the system and encrypts stored data.

This Ransomware has affected organizations in the United States, Latin America and Europe.

After encryption, the ransomware leaves several references to Cuba as extensions in all encrypted files, (Example: 1.pdf.cuba) and also a string ‘FIDEL.CA’ embedded in its header and probably points to Fidel Castro, which is another reference to Cuba.

Ransomware Recovery FAQ

Every day, ransomware attacks get better and better. After a successful attack attempt, ransomware quickly maps the user’s most important files to begin encryption. Microsoft Office files, databases, PDFs and design are among its main targets.

Ransomware is designed to be unnoticeable, so it can disable all system defenses without being noticed and start the process of encrypting the files. Even though ransomware can go unnoticed by the system, it can still be noticed by the user, because ransomware uses the system’s own resources to do the encryption, this can slow down the system. Ransomware also changes file extensions. So be on the lookout for these signs: System slowdown and extensions being added to files.

You can also start the diagnostics to identify threats with your antivirus, the vast majority of antiviruses have this function.
But there are cases where the encryption was interrupted by the user, some files had already been affected and this caused an error in the encryption and even the hackers could not restore the files, even with the decryption key. In these cases only a data recovery company, such as Digital Recovery, can recover the files.
