AES encryption algorithm is used by the nasty Kriptovor Ransomware which encrypts files with it adding the .Just file extension to their original one. This dangerous cyber-threat then adds an MESSAGE.txt file which gives the infected user PC unique ID and asks to contact the e-mail of the cyber-criminals for more information. Since this is done with a purpose to pay a huge ransom fee which is no guarantee you will get your files back, experts advise users not to contact the e-mail and try alternative methods to restore your files and remove this malware, like the ones posted in this article.
Threat Summary
Name
Kriptovor
Type
Ransomware
Short Description
The malware encrypts users’ files after force restarting their PC, dropping ransom message, named “MESSAGE.txt”
Symptoms
The user may witness ransom messages and “instructions”.
Windows Data Recovery by Stellar Phoenix Notice! This product scans your drive sectors to recover lost files and it may not recover 100% of the encrypted files, but only few of them, depending on the situation and whether or not you have reformatted your drive.
Kriptovor Ransomware and Its Distributing
To infect users, Kriptovor ransomware may take advantage of the freedom of torrent websites and post its malicious executables to be concealed and appear as if they were:
Game crackfixes.
Key generators for programs.
Fake installers of programs.
Not only this, but Kriptovor is also reported by researchers at the FireEye blog to spread via malicious e-mail addresses which have URLs leading to third-party sites containing a .PDF attachment:
Source:fireeye.com
The e-mail message invites the user to download the PDF file which opens a resume of usually a female candidate for work. The resume is reported to contain a malicious script which activates an Infostealer component.
More About Kriptovor Ransomware
As soon as the Infostealer is activated, it begins to check for the following information on the affected computer:
Internet connection details.
Processes actively running on the machine of the user.
Name of the machine.
Outgoing and ingoing connection and all IP addresses connected to the victim as well as its own.
Registry entries information.
After this is done, the virus checks if the computer is on a virtual machine and if it is, Kriptovor shuts down. If not, it downloads its payload, called temporary.rar from the following web domain:
→ http://plantsroyal(.)org/css/salomon.rar
Kriptovor ransomware then hides the malicious file and adds a registry string, named AdobeUpdate which runs the encryptor once when you start Windows:
The ransom note is in a MESSAGE.txt file which may be dropped onto the desktop of the user PC as well as affected folders. The message states the following:
→„Унать стоимость декриптора можно, написав письмо на адрес: {cyber-criminals’ e-mail address here} В теме письма укажите ваш ID:2083043332 Убедительная просьба не пьiтаться расшифровать файльi сторонними инструментами. Въi можете их окончательно испортить и даже оригинальньiй дешифровщик не поможет. Обращения принимаются до (Date) После (Date) любьie обращения будут игнориоваться. Письма обрабатьiвается автоматической системой. Возможньi задержки ответов“
What is important in this ransom message is that the cyber-criminals warn the infected used not to try and directly decrypt the files. This strongly suggests that a CBC-mode may have been used to encrypt the files.
Remove Kriptovor Ransomware and Try To Get Your Files Back
In order to delete Kriptovor Ransomware, we strongly advise you to focus on automatically removing it by using an advanced anti-malware program. This may automatically find all files and registry entries which you would have difficulty removing manually because they are concealed.
If you with to get back your files, we advise NOT TO TRY direct decryption because there may be a CBC-mode on the encrypted files which may break them if you use third-party decryptors, making them lost forever. Instead, we advise to follow the alternative file-restoration solutions in step “3. Restore files encrypted by Kriptovor” below. They may not be 100 percent effective, but they might also help to restore at least small portion of your files.

4. Try to Restore files encrypted by Kriptovor
Try to Restore Files Encrypted by Kriptovor
Ransomware infections and Kriptovor aim to encrypt your files using an encryption algorithm which may be very difficult to decrypt. This is why we have suggested several alternative methods that may help you go around direct decryption and try to restore your files. Bear in mind that these methods may not be 100% effective but may also help you a little or a lot in different situations.
Method 1: Scanning your drive’s sectors by using Data Recovery software. Another method for restoring your files is by trying to bring back your files via data recovery software. Here are some suggestions for preferred data recovery software solutions:
Method 2: Trying Kaspersky and EmsiSoft’s decryptors. If the first method does not work, we suggest trying to use decryptors for other ransomware viruses, in case your virus is a variant of them. The two primary developers of decryptors are Kaspersky and EmsiSoft, links to which we have provided below:
To restore your data in case you have backup set up, it is important to check for Volume Shadow Copies, if ransomware has not deleted them, in Windows using the below software:
Method 4: Finding the decryption key while the cryptovirus sends it over a network via a sniffing tool.
Another way to decrypt the files is by using a Network Sniffer to get the encryption key, while files are encrypted on your system. A Network Sniffer is a program and/or device monitoring data traveling over a network, such as its internet traffic and internet packets. If you have a sniffer set before the attack happened you might get information about the decryption key. See how-to instructions below:
