Remove .onion virus

About .onion virus

.onion is the extension added to files encrypted by Cry128, a ransomware that comes from the CryptON family. When it comes to malware, ransomware is probably one of the most dangerous kinds of infections out there because it can encrypt your files and demand that you pay to get them back. Usually ransomware developers use rather simple ways to infect computers but in the case of .onion virus and other ransomware from the same family, brute force RDP (remote desktop services) attacks are performed.

If you find that your files have been encrypted, you might consider paying but we must warn you that it may not lead to file decryption because the criminals could just take your money and not decrypt your files. Paying is not very wise especially because there is a free decryptor available, developed by Emsisoft. Getting files from backup is also an option but you should first delete .onion virus from your system.

How does .onion virus spread?

According to specialists, .onion virus can infect your system by performing brute force RDP attacks. That basically means that the ransomware logs into your server and infects the system. Usually, ransomware use more basic ways to spread and usually send out thousands of infected emails with attachments to unsuspecting users. When users open those attachments, they end up allowing the ransomware to enter their computers. This is why security specialist warn users not to open email attachments carelessly. Fake downloads are also commonly used. This is why it is not recommended to download anything from dubious sites.

Is .onion virus really that dangerous?

As soon as your computer is infected, it will encrypt most of the files on your computer and delete all shadow copies, which means you will not be able to recover your files that way. It adds the .onion file extension to all affected files so it will be clear which files have been encrypted. A ransom note will then make an appearance. You will obviously be asked to pay a ransom to get your files back but we do not recommend doing that. One of the main reasons is that by paying you would be basically supporting cyber criminals and their future projects. Also, they could just take the money and leave your files encrypted. In the end, the choice is yours but investing that money into backup would be a more reasonable choice. Had you had backup, you could just remove .onion virus and get your files back. Additionally, Emsisoft’s Fabian Wosar has developed a decryptor that should be able to recover your files. Before carrying out .onion virus removal, you should check the instructions for file decryption available on their site.
