About OnyonLock

OnyonLock is a file-encrypting type of virus, more commonly referred to as ransomware. If you manage to infect your computer, it will encrypt your files and demand that you pay to get them back. This is your typical ransomware behavior. And ransomware may have different spread method and demand differing amounts of money but they all are essentially the same.


The reason you got infected was most likely because you opened an infected email attachment. Emails are the most common method ransomware developers use because it still manages to infect people, even years later. Paying the ransom is not recommended because you could be scammed out of your money. There is nothing forcing the criminals to restore your files after you pay. Do not forget they are crooks. Instead, you ought to delete OnyonLock and get files from backup, if you have it.

OnyonLock spread methods

The most likely method used was spam email attachments. An infected file is attached to free software and sent out to hundreds of users. Usually, your email provider will send these kinds of emails to the spam folder or just block them fully. If you do happen to get it and open the attachment, the ransomware would download onto your computer. To avoid this, always be vigilant when opening emails. Even if it seems completely legitimate, be cautious and make sure the attachment is safe to open. You should also refrain from downloading software from unreliable sources. Fake downloads are a great way to spread ransomware. If you need some kind of program, make sure the source is secure.

What does OnyonLock do exactly?

It might not be obvious at first and by the time you notice your files are encrypted, it’s too late. OnyonLock will start the encryption process the moment is enters your computer. All affected files will have the .onyon file extension so it will be obvious which files have been encrypted. You will then find a ransom note and it will explain what is going on and how to proceed. There is no set price for the decryption, the hackers claim it depends on how fast you write them. They give decrypter@onyon.su as the email address you need to use. Again, do bear in mind that you are dealing with cyber criminals who could just take your money and provide nothing in return. There is no reason why you should trust them. Instead, you ought to remove OnyonLock and invest that money into reliable backup so that this situation is avoided. If you did have backup prior to infection, you can safely delete OnyonLock and restore your files.
