unlckr@protonmail.com ransomware is an alternative name for recently emerged Unlckr virus. Researchers suspect that malware is related to Unlock92 ransomware. It seems that Russian-speaking computer users are in the target field of the ransomware. The virus uses RSA-2048 encryption algorithm and appends .cr020801 file extension to affected files. The instructions how to recover files are delivered in ! _INSTRUKTSYA _ !. txt file.

The first task ransomware[1] does on the affected computer is making connections to multiple remote hosts. Once Command and Control (C&C) server responds, malware starts completing received the tasks. Before starting data encryption, unlckr@protonmail.com virus might modify Windows Registry in order to run on system startup. What is more, it might install other malicious files or affect numerous system processes.

Once system modifications are made, unlckr@protonmail.com virus starts looking for targeted file extensions. For data encryption, it uses a strong RSA-2048 cipher that prevents users from opening or using necessary files. Once this procedure is over, all the encrypted files have .cr020801 file extension. In order to use the data again, users have to get a private decryption key.

The ! _INSTRUKTSYA _ !. txt file offers to obtain a necessary decryption key. In the ransom note, victims are told to contact cyber criminals via unlckr@protonmail.com email and send one encrypted file. Within 24 hours hackers should respond and give further instructions. However, it may not happen.

Cyber criminals warn that if victims do not receive the answer in one day, they supposed to access a particular website via Tor browser. In the website, people will find a current contact email. Thus, they have to send another message.

Communicating with cyber criminals and following their orders is not recommended. We can assure that they won’t allow using decryptor for free. They may ask a huge amount of money for the exchange. If you are thinking about this shady deal, you should be aware that there’s a huge possibility that you will lose your money. Cyber criminals may disappear as soon as their get the ransom.

How to prevent from getting ransomware

Stream videos without limitations, no matter where you are

There are multiple parties that could find out almost anything about you by checking your online activity. While this is highly unlikely, advertisers and tech companies are constantly tracking you online. The first step to privacy should be a secure browser that focuses on tracker reduction to a minimum.

Even if you employ a secure browser, you will not be able to access websites that are restricted due to local government laws or other reasons. In other words, you may not be able to stream Disney+ or US-based Netflix in some countries. To bypass these restrictions, you can employ a powerful Private Internet Access VPN, which provides dedicated servers for torrenting and streaming, not slowing you down in the process.

Data backups are important – recover your lost files

Ransomware is one of the biggest threats to personal data. Once it is executed on a machine, it launches a sophisticated encryption algorithm that locks all your files, although it does not destroy them. The most common misconception is that anti-malware software can return files to their previous states. This is not true, however, and data remains locked after the malicious payload is deleted.

While regular data backups are the only secure method to recover your files after a ransomware attack, tools such as Data Recovery Pro can also be effective and restore at least some of your lost data.
