Locked_file virus

Locked_file ransomware is a new computer virus that targets Windows operating systems. The virus is very similar to .locked file extension virus, however, it adds a slightly modified file extension – .[restoreassistant2@tutanota.com].LOCKED_FILE. The virus aims to encrypt[1] all files as fast as possible, and afterward, it drops !HOW_TO_UNLOCK_FILES!.html file to provide a ransom-demanding message to the victim.

The Locked_file virus also modifies the original file name, replacing it with a set of random characters.

The ransom note launches via default web browser and suggests that “all files have been encrypted with strong cryptographic algorithm.” The threatening message suggests that the victim has 72 hours to contact cyber criminals via restoreassistant2@tutanota.com. The note also contains victim’s personal ID, which is used to identify each victim.

Traditionally, criminals provide a “test our decryption tool” feature and ask to send some files along with the identification code to their email address.

However, at the moment ransomware is under analysis, so it is unknown whether a free data recovery is possible. Please stay patient, because malware analysts might come up with a free .locked_file decryption tool.

Novirus.uk[2] experts share these tips that can help you to protect yourself against a ransomware attack:

  • To prevent ransomware attacks, we suggest installing a good security product and creating a data backup[3]. These are essential steps to take towards better computer security.
  • In addition, we strongly recommend staying away from questionable emails you might receive in your email account. If you noticed a suspicious letter from someone who wasn’t supposed to contact you – be it a well-known company or a suspicious stranger, do not open file attachments or links included in the email. These might appear to be straight paths to a complete data loss.
  • Finally, keep your programs up-to-date. It means that you should always use the latest versions of software so that cyber criminals couldn’t exploit vulnerabilities in them.

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.
