What is Unlckr ransomware virus?

Unlckr ransomware targets Russian-speaking computer users

Unlckr is a recently discovered file-encrypting virus. Ransomware uses RSA-2048 cryptography to encode various files. During data encryption, it appends .cr020801 file extension to audio, video, text, image, archives, databases, and other popular files. When files are taken to the hostage, malware provides data recovery instructions in the text file called ! _INSTRUKTSYA _ !. txt. However, instead of paying the ransom, you should focus on Unlckr removal with reputable malware removal program such as FortectIntego.

The research has shown that this crypto-malware might be related to Unlock92 ransomware. It also aims at Russian-speaking computer users because the ransom note is written only in the Russian language.

The ransom-demanding message asks to send one of the encrypted files to unlckr@protonmail.com. However, if authors of Unlckr ransomware does not respond within 24 hours, victims have to take further actions. They have to install TOR browser[1] and access a particular website that reveals a new criminals' email address.

Currently, it’s unknown how much money cyber criminals are asking for data recovery. It seems that the size of the ransom may vary based on the amount of encrypted files. However, you should not follow hackers’ orders. They may take the money and leave you with nothing. Instead of risking to experience an even bigger loss, you should remove Unlckr from the device as soon as you notice its appearance.

Apart from encrypting targeted data, Unlckr will also make changes to the Windows OS. Malware might make registry entries, install malicious files, delete Shadow Volume Copies or inject malicious codes into legitimate system processes. All these activities make the system vulnerable and might open the backdoor to other malware. Thus, it’s crucial to get rid of the virus as soon as possible in order to avoid bigger damage.

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.
