How did the kuub ransomware install on my computer?
Kuub ransomware is distributed by spam email containing infected attachments or by exploiting vulnerabilities in the operating system and installed software.
Cybercriminals send spam in an email with false header information, making you think it comes from a shipping company like DHL or FedEx. The email tells you that they tried to deliver a package to you, but for some reason failed.
Sometimes emails pretend to be notifications of a shipment you’ve made. Either way, you can’t resist the curiosity of what the mail is referring to and open the attached file (or click on a link embedded in the email). And with that, your computer is infected with Kuub ransomware.
Kuub ransomware has also been observed attacking victims by hacking open Remote Desktop Services (RDP) ports. Attackers are looking for systems running RDP (TCP port 3389), and then brutally trying to force the systems password.
What is kuub ransomware
The Kuub ransomware restricts access to data by encrypting files. He then tries to extort money from the victims by asking for a “ransom”, in the form of a Bitcoin cryptocurrency, in exchange for access to the data. This virus targets all versions of Windows, including Windows 7, Windows 8 and Windows 10.
When this virus is installed on your computer, it creates a randomly named executable in the% AppData% or% LocalAppData% folder. This executable will be launched and will start scanning all drive letters on your computer to find the data files to encrypt.
Kuub ransomware searches for files with certain file extensions to encrypt. The files it encrypts include important documents and productivity files such as .doc, .docx, .xls, .pdf, among others. When these files are detected, this infection changes the extension to Kuub and can therefore no longer be opened.
Once your files are encrypted with the Kuub extension , this ransomware will create the ransom note of the _readme.txt file in each folder indicating that a file has been encrypted and on the Windows desktop. These files are located in each folder where a file has been encrypted and contain information on how to contact cybercriminals and recover your files.
When the infection has finished scanning your computer, all shadow volume copies stored on the affected computer will also be deleted. Thus, you cannot use instant volume copies to restore your encrypted files.

When this ransomware infects your computer, it analyzes all the drive letters corresponding to the targeted file types, encrypts them, then adds the Kuub extension to them. Once these files are encrypted, they can no longer be opened by your normal programs.
Once the ransomware software has finished encrypting the victim’s files, a ransom note containing instructions for contacting these cybercriminals ( [email protected] or [email protected] ) is displayed.

No, unfortunately, it is impossible to recover files encrypted by the Kuub ransomware because the private key required to unlock encrypted files is only available via cybercriminals.
Do not pay money to recover your files. Even if you pay the ransom, there is no guarantee that you will regain access to your files.
