How to remove ONI Ransomware and decrypt .ONI files

What is ONI Ransomware?

ONI is a data-kidnapping virus that extorts money from victims. The scheme of the work of this virus is no different from any other ransomware. At first, it looks for ways to break into the victim’s PC and block anything that may stop the virus. Then, the encryption process starts which subsequently makes users’ data unreadable. To find out the amount of ransom, the user is offered to send dedicated ID number to their email. The point is, a lot of people fall into the trap of cyber crooks paying them money. There are a lot of cases where cybercriminals do not help their victims, even if they pay up. Remember, you are up against fraudsters so nobody will give any guarantees that they will fulfill their commitments. Hence, there is a high risk of being left without decryptor and money. Instead, you may try using this guide to remove ONI Ransomware and decrypt .ONI files without spending any money.

ONI ransomware

The principle of work of the ransomware is always the same – to encrypt files and then to require payment. ONI Ransomware encodes users’ personal files via XTEA encryption algorithm. As a result, each infected file will be renamed (HEX) and appended with “.ONI” extension. For example, file “myfamily.jpg” will turn into “352E7A8022.ONI”. Once all the data is encrypted, the ransomware creates RESTORE_ONI_FILES.txt file, where the user may find the demands of criminals:
