What is Odin Ransomware

Odin Ransomware is the latest version of the infamous Locky ransomware. As we know, previously it added .locky and .zepto extensions. Now it uses .odin extension. Technically, it is the same Locky virus, that uses same asymmetric cryptography. However, now key is changed and currently AutoLocky Decryptor that was able to decrypt .locky files can do nothing with .odin files. Now ransomware uses system process (rundll32.exe) to execute malicious process and start encryption process. Odin changes desktop background image to the same picture with instructions to pay the ransom. Ransom is huge (3 Bitcoins or ~$1800). Malware creates 3 files (_HOWDO_text.html, _HOWDO_text.bmp, and _HOWDO_text.html) and copies them to the folder with encrypted files.

Note: Hackers usually do not send any decryptors or decryption keys even if you pay them. Wait until working decryptor appears or try to restore .odin files manually from backup or using instructions below.

In this article you will find complete guide to remove Odin ransomware and decrypt .odin files in Windows 10, Windows 8, Windows 7 and earlier versions.

How Odin Ransomware infected your PC

Odin like Locky or Zepto uses e-mail attachments, with 2 types of files (.zip and .docm). First one uses archived java-script files. Second one uses macros inside the document, that will then download main executable. JavaScript files icons may look like text files and unsuspecting users may click on them. Virus assigns certain ID with the victims, that is used to name those files and to send decryption key. In order to prevent infection with this type of threats in future we recommend you to use SpyHunter 5 and HitmanPro with CryptoGuard.
