Description of Onyx ransomware virus

Onyx ransomware attacks computer users from Georgia

Onyx ransomware virus is one of the latest cyber threats which targets a considerably small group of computer users. The creators of the ransomware are not so ambitious and only targets people living in Georgia. Therefore, if you live in this country, you should take some precautions in order to avoid this file-encrypting virus: install a strong antivirus program, get used to double check the information before opening email attachments, do not browse on high-risk websites and do not install questionable software or their updates from suspicious domains. Besides, you should make backup copies of all your important files. One Onyx virus gets inside the computer it corrupts all your personal data. The possibility that some of your documents, pictures or audio collection will survive the attack is little. Malware acts silently and only when it finishes file encryption process, it informs victim what have happened by changing affected computer’s background picture and leaving a ransom note. If you are one of the unlucky ones who have encountered this ransomware, you should not let cyber criminals blackmail you. Hackers ask to pay the ransom for a possibility to decrypt locked files, but instead of reaching for your credit card, remove Onyx from the computer. The virus is capable of installing additional malware that makes your computer’s state even more vulnerable. Therefore, scan your PC with ReimageIntego or other reputable malware removal program and start virus elimination process.

The ransom note delivered by Onyx ransomware is written in Georgian. Some ransomware viruses offer to read messages in other languages as well, so it seems the authors of this ransomware are not willing to spread broader and target their homeland only. However, hackers might have failed a little or Onyx is their first attempt to create a ransomware. They haven’t provided a necessary Bitcoin wallet address, so it’s impossible to pay the ransom even if you consider doing it. On the one hand, it’s impossible to decrypt files locked by the ransomware; on the other – you saved 100 US dollars that cyber criminals asked you to pay. What should you do now? Initiate Onyx removal.

How to prevent from getting Onyx ransomware virus

Securely connect to your website wherever you are

Sometimes you may need to log in to a content management system or server more often, especially if you are actively working on a blog, website, or different project that needs constant maintenance or that requires frequent content updates or other changes. Avoiding this problem can be easy if you choose a dedicated/fixed IP address. It's a static IP address that only belongs to a specific device and does not change when you are in different locations. 

VPN service providers such as Private Internet Access can help you with these settings. This tool can help you control your online reputation and successfully manage your projects wherever you are. It is important to prevent different IP addresses from connecting to your website. With a dedicated/fixed IP address, VPN service, and secure access to a content management system, your project will remain secure.

Reduce the threat of viruses by backing up your data

Due to their own careless behavior, computer users can suffer various losses caused by cyber infections. Viruses can affect the functionality of the software or directly corrupt data on your system by encrypting it. These problems can disrupt the system and cause you to lose personal data permanently. There is no such threat if you have the latest backups, as you can easily recover lost data and get back to work.

It is recommended to update the backups in parallel each time the system is modified. This way, you will be able to access the latest saved data after an unexpected virus attack or system failure. By having the latest copies of important documents and projects, you will avoid serious inconveniences. File backups are especially useful if malware attacks your system unexpectedly. We recommend using the Data Recovery Pro program to restore the system.
