Researchers from the security firm Tesorion have developed a decryptor tool that works on Nemty versions 1.4 and 1.6. The company is allowing victims to retrieve the decryption key by generating it on its own servers. The tool is also working with Europol to get its decryptors included in their NoMoreRansom project. The decryptor currently supports only a limited number of file extensions, anyway, researchers are working to improve it and support other file types. Victims can contact the Tesorsorion CSIRT and request help with the Nemty Ransomware, in turn the company will then send a link to the decryptor that will allow you to decrypt the files.”]
