Unfortunately, because the key is unique to each of the infected victims, restoring files without it becomes almost impossible. Nevertheless, the first step to secure computer is to remove Boris virus from the infected device. We highly recommend using FortectIntego or any other reputable security software.

The ransomware is using hidden-tear.exe executable to infect machines, and many AV engines recognize[2] it as a HiddenTear virus. Although most of the variants of this malware are decryptable, it is unclear whether or not the decryptor will work for Boris ransomware. Nevertheless, we suggest users try it, as it may succeed.

Other file recovery methods include:

  • Restoring files from a backup. External HDD or USB stick, as well as virtual cloud services, will do;
  • Using third-party software. These applications might be able to help you with file decryption, although chances are not high. Please see the instructions below this article;
  • Waiting for an independent security researcher to crack malware's code and create a decryptor.

As you can see, the recovery is possible, and paying cybercrooks is not the option to choose.

There are two versions of ransom note that are being distributed – one in English and another one in Russian. This can implicate that .boris ransomware authors might be English or Russian, or specifically target people from these countries. Nevertheless, the infection can occur anywhere in the world. The ransom note does not disclose much:

Boris ransomwareBoris is a cryptovirus which uses a unique encryption code to lock up important data. Avoid ransomware-type infections

To stay safe from ransomware, you have to know how it is distributed. First, let's talk about virus distribution ways. You can catch such infection by browsing various suspicious sites, clicking on suspicious hyperlinks, or downloading repacked or cracked software. Thus, you should avoid visiting questionable websites and use trusted sources for your downloads. Remember that any executable can be malicious. Thus, scan it with security software before opening.

However, the most prevalent ransomware distribution method is via phishing emails. Cybercrooks employ bots to send out thousands of spam emails daily which reach random or targeted users. The malicious payload can be carried inside the attachment or can be transferred once the user clicks on a cleverly disguised hyperlink that is downloaded from a remote server. Thus, do not open attachments or click on links inside emails from unknown sources.

Other ransomware infiltration methods include:

  • Unprotected RDP configuration;
  • Exploit kits;[3]
  • Web injects;
  • Fake updates, etc.

Therefore, make sure you update your software as soon as new patches are out and use strong passwords for all your accounts.

How to prevent from getting ransomware

Do not let government spy on you

The government has many issues in regards to tracking users' data and spying on citizens, so you should take this into consideration and learn more about shady information gathering practices. Avoid any unwanted government tracking or spying by going totally anonymous on the internet. 

You can choose a different location when you go online and access any material you want without particular content restrictions. You can easily enjoy internet connection without any risks of being hacked by using Private Internet Access VPN.

Control the information that can be accessed by government any other unwanted party and surf online without being spied on. Even if you are not involved in illegal activities or trust your selection of services, platforms, be suspicious for your own security and take precautionary measures by using the VPN service.

Backup files for the later use, in case of the malware attack

Computer users can suffer from data losses due to cyber infections or their own faulty doings. Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact – you can set this process to be performed automatically.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware strikes out of nowhere. Use Data Recovery Pro for the data restoration process.
