Things to known about recently discovered One ransomware virus

One ransomware has been recently spotted attacking computer users. Cyber criminals usually spread malicious payload via misleading emails. When people opens an infected email attachment, the virus is installed and executed on the computer. This cyber infection is designed to camouflage itself as legitimate system processes, such as svchost.exe[1] or Chrome.exe.[2] For this reason, it can stay on the system undetected for a while and perform its nasty tasks. There’s no doubt that the primary function of the One virus is to encrypt files. As soon as it gets inside, it starts scanning the system. There’s no doubt that it is looking for the data for the encryption. Just like many other similar cyber threats, this one also aims at the most popular files such as MS Office documents, various multimedia files, databases, archives, and much more widely used data. To all corrupted files it adds .one file extension. Sadly, there’s not much what you can do with documents, pictures and other records encrypted by One malware. Although if you have data backups, meeting this crypto-malware does not cause you much damage.[3] Otherwise, you are in an unpleasant situation.

The creators of the One virus gives victims short instructions what they need to do with encrypted files in the ransom note called Recupere seus arquivos aqui.txt. This text file is dropped on the system as soon as data encryption is other. The ransom demanding message is written in the Portuguese language. Thus, Portuguese-speaking computer users are in the target eye of the ransomware. In the ransom note, victims find their unique ID and are asked to send it to the provided email address. Within 24 hours, they are supposed to receive and email with the necessary decryption key. However, you should not contact cyber criminals because they won’t provide decryption software for free. First of all, hackers will tell you how much Bitcoins their decryption software costs.[4] Then, they might use blackmailing or psychologic terror tactics to persuade you to pay the ransom. Lastly, you may not receive the promised software. Thus, instead of having a discussion with criminals, you should focus on One removal. Ransomware elimination is performed using malware removal tools such as Reimage Reimage Cleaner Intego or SpyHunter 5Combo Cleaner. However, the virus might be designed to block access to the security programs. In this case, take a look at the instructions below. They will help you to deal with obstacles and remove One from the system.

Thus, the dangerous payload might be delivered straight to your inbox as an obfuscated file. The email might inform about a necessity to verify some details in the attached invoice or another important document. Crooks can pretend to be from various organizations and find numerous reasons to motivate you to open the attachment. What is more, One hijack might also occur if you click on an infected link sent in the email or social media. Thus, before clicking on unknown attachments and strange links, make sure that it’s actually safe to open. Developers of the ransomware also successfully use malvertising as another distribution method. Malware-laden ads might be placed even on legitimate and well-known websites.

Below you will find three alternative methods that might help you to restore files encrypted by One malware. However, we cannot assure that they will be effective and retrieve all your data. Though, it’s still worth giving a try.

If your files are encrypted by One, you can use several methods to restore them:

Data Recovery Pro for restoring files encrypted by One ransomware virus

Data Recovery Pro might be useful in data recovery if you do not have backups. This tool is designed to restore various damaged files. Thus, it might help you as well.

  • Download Data Recovery Pro;
  • Follow the steps of Data Recovery Setup and install the program on your computer;

  • Restore them.

  • Here, check each of available copies of the file in “Folder versions”. You should select the version you want to recover and click “Restore”.

ShadowExplorer might help to restore files encrypted by One ransomware

Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from One and other ransomwares, use a reputable anti-spyware, such as Reimage Reimage Cleaner Intego, SpyHunter 5Combo Cleaner or Malwarebytes

Access your website securely from any location

When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. It is a hassle when your website is protected from suspicious connections and unauthorized IP addresses.

The best solution for creating a tighter network could be a dedicated/fixed IP address. If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for server or network manager that need to monitor connections and activities. This is how you bypass some of the authentications factors and can remotely use your banking accounts without triggering suspicious with each login. 

VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world. It is better to clock the access to your website from different IP addresses. So you can keep the project safe and secure when you have the dedicated IP address VPN and protected access to the content management system.

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

Computer users can suffer various losses due to cyber infections or their own faulty doings. Software issues created by malware or direct data loss due to encryption can lead to problems with your device or permanent damage. When you have proper up-to-date backups, you can easily recover after such an incident and get back to work.

It is crucial to create updates to your backups after any changes on the device, so you can get back to the point you were working on when malware changes anything or issues with the device causes data or performance corruption. Rely on such behavior and make file backup your daily or weekly habit.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware occurs out of nowhere. Use Data Recovery Pro for the system restoring purpose.
