Odin ransomware encrypts personal files, changes the file names, adds the .odin extension to files, and demands a ransom to decrypt files
Odin is a file extension associated with Locky ransomware. The ransomware is very similar to zepto ransomware because it is named after the file extension although the name of the file extension is not the exact name of the variant of malware.
Like most other types of ransomware, Odin ransomware will encrypt the files on your computer, randomize the file name, and add a new extension to the files it encrypts. The file extension that this ransomware appends to files is .odin. In addition, Odin ransomware will leave a note named HOWDO_text.html in every folder it encrypts files in. It will also change the background of Windows Desktop to the ransom note and use a lock-screen to restrict access to the computer. The note files, desktop background, and lock-screen contain a ransom note that explains what happened to the files and how to pay a ransom in order to acquire a key to decode the compromised files.
