KRIPTOVOR virus Removal Guide

What is KRIPTOVOR virus?

KRIPTOVOR is ransomware that threatens computer users since 2014

KRIPTOVOR ransomwareKRIPTOVOR is a ransomware virus that mostly targets Russian companies.

KRIPTOVOR is a file-encrypting virus that uses AES cryptography to make files unusable on the affected machine. Originally, it adds .Just file extension to the data, but other versions of the virus append .neitrino and .excuses suffixes. The malware was first detected in 2014, though it is still active in 2018.

KRIPTOVOR virus mainly targets Russian[1] companies and spreads via emails.[2] The majority of malicious letters have a subject line “Резюме на вакантную должность” (“Resume for the vacant post”). In the body criminals tell to double-click the attached file in order to open a resume in Adobe Reader:

Дважды кликните, чтобы открыть резюме в Adobe Reader

KRIPTOVOR spam emailKRIPTOVOR spreads via malicious spam emails that include fake resume.

However, the attachment is a corrupted file that includes malicious content instead of person's resume. Once opened, malware downloads password-protected RAR file which includes AdobeSystems.exe. This file is the executable of the KRIPTOVOR.

KRIPTOVOR ransomware virusKRIPTOVOR ransomawre virus is executed when a victim opens obfuscated resume in the PDF file.

On the affected machine, KRIPTOVOR ransomware does not act like typical ransomware. It encrypts files using LockBox 3 which uses AES cryptography. Additionally, it scans for login and password information that might be saved on the targeted data. Thus, the virus also aims to extract potentially useful information too.

When all files are locked, KRIPTOVOR also delivers a ransom note in the Russian language. The information about the attack and data recovery possibilities are included in the MESSAGE.txt file. The translation of the threatening message provided below:

The cost of the decryptor can be obtained by writing an email to:
In the subject line please include your ID:[redacted]
Please do not try to decrypt the files using third-party tools.
You can completely corrupt them, and even the original decryptor will not help.
Requests will be accepted until [Date]
After [Date] requests will be ignored.
Emails are handled automatically by the system.
There may be a delay in responses

According to the research, cyber criminals use different email addresses to communicate with victims. Currently known addresses:


KRIPTOVOR ransom noteAuthors of KRIPTOVOR provides a contact email address for victims who are interested in data recovery.

Criminals ask to contact them the same day as the infection occurred. However, security specialists do not recommend doing that because it may lead to money loss. Authors of ransomware usually demand to pay the ransom in cryptocurrency, but they may never give working decryption key.[3] For this reason, we recommend proceeding with KRIPTOVOR removal.

As you already know, the virus might try to extract personal data, so it’s better to terminate it as soon as possible. In order to remove KRIPTOVOR correctly and avoid possible damage to the system, you need to employ FortectIntego or another anti-malware tools. If you have difficulties with elimination, follow the guide below. KRIPTOVOR virusKRIPTOVOR is a malicious program that is designed to encrypt files and demand to pay the ransom in order to for the decryption tool.

Versions of KRIPTOVOR

Neitrino ransomware virus. The virus was first detected in autumn 2015 spreading in Russia via malicious spam emails that include obfuscated PDF file. It uses AES[4] cryptography appends either .neitrino or .NEITRINO file extension. Then it downloads a ransom note in MESSAGE.txt in each folder that contains locked files.

On the affected machine, malware is executed from AdobeUpdate.exe and svchost.bat files which are dropped on a system when a user opens a malicious email attachment. The purpose of the virus is to make people pay 5,000 rubles or more for file recovery.

KRIPTOVOR Neitrino virusNeitrino virus is a version of KRIPTOVOR ransomware that acts very similar to the original version.

According to the ransom note, victims have to send an email to or address in order to get further recovery instructions. Though, it is not recommended process. It’s better to remove KRIPTOVOR Neitrino virus and try recovering files from backups or using third-party tools.

Excuses ransomware virus. In 2018, a new variant of KRIPTOVOR has been spotted spreading and targeting Russian users again. This version uses filemarker 0x20000000 and appends .excuses file extension to the targeted files.

Authors of ransomware ask to contact them via and send their unique victim’s ID number if they want to get back access to the files. Such information is provided in the Russian language. However, apart from changed contact email address, the text of the ransom note did not change:

Приобрести декриптор можно до [Date]
Запросить стоимость:

В ТЕМЕ письма укажите ваш ID: [redacted]
Письма без указания ID игнорируются.

Убедительная просьба не пытаться расшифровать файлы сторонними инструментами.
Вы можете их окончательно испортить и даже оригинальный декриптор не поможет.

Заявки обрабатываются автоматической системой.

KRIPTOVOR Excuses virusKRIPTOVOR started adding .excuses file extension in June 2018.

We want to remind that it’s not a good idea to trust cyber criminals. They will demand to pay the ransom and might disappear as soon as you send a couple of hundred of dollars. Hence, focus on KRIPTOVOR removal and try alternative ways to recover your files.

Obfuscated email attachments might include ransomware payload

The main way how ransomware viruses spread is malicious spam email attachments.[5] Though, not all dangerous emails end up in the spam folders. Crooks might use advanced techniques and make sure that their letter appears in the main emails box. However, they might be identified by these signs:

  • weird or mismatching email address;
  • lack of credentials;
  • empty body;
  • urge to open the attachment;
  • grammar and spelling mistakes.

If the letter does not seem to be sent for you or you did not expect to receive it, stay away from the attachment. Also, you can check it with online file scanners before opening it.

Removal of the KRIPTOVOR ransomware virus

The only correct way to remove KRIPTOVOR from Windows PC is to employ professional software. Tools like FortectIntego or Malwarebytes can quickly detect malicious components and eliminate them from the device. However, if you have some difficulties, you should reboot the device to Safe Mode with Networking as explained below.

After KRIPTOVOR removal, you can plug in the external hard drive with backups or try our suggested third-party tools. You can find them listed below. However, we want to stress out that the official decryptor is not released yet. So, chances to full recovery are low if you do not have backups.

Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from KRIPTOVOR and other ransomwares, use a reputable anti-spyware, such as FortectIntego, SpyHunter 5Combo Cleaner or Malwarebytes

How to prevent from getting ransomware

Protect your privacy – employ a VPN

There are several ways how to make your online time more private – you can access an incognito tab. However, there is no secret that even in this mode, you are tracked for advertising purposes. There is a way to add an extra layer of protection and create a completely anonymous web browsing practice with the help of Private Internet Access VPN. This software reroutes traffic through different servers, thus leaving your IP address and geolocation in disguise. Besides, it is based on a strict no-log policy, meaning that no data will be recorded, leaked, and available for both first and third parties. The combination of a secure web browser and Private Internet Access VPN will let you browse the Internet without a feeling of being spied or targeted by criminals. 

No backups? No problem. Use a data recovery tool

If you wonder how data loss can occur, you should not look any further for answers – human errors, malware attacks, hardware failures, power cuts, natural disasters, or even simple negligence. In some cases, lost files are extremely important, and many straight out panic when such an unfortunate course of events happen. Due to this, you should always ensure that you prepare proper data backups on a regular basis.

If you were caught by surprise and did not have any backups to restore your files from, not everything is lost. Data Recovery Pro is one of the leading file recovery solutions you can find on the market – it is likely to restore even lost emails or data located on an external device.
