Ransom Note
NOT YOUR LANGUAGE? USE https://translate.google.com What's the matter with your files? Your data was secured using a strong encryption with RSA4096. Use the link down below to find additional information on the encryption keys using RSA4096:https://en.wikipedia.org/wiki/RSA_(cryptosystem) What exactly that means? It means that on a structural level your files have been transformed. You won't be able to use, read, see or work with them anymore. In other words they are useless, however, there is a possibility to restore them with our help. What exactly happened to your files? *** Two personal RSA4096 keys were generated for your PC/Laptop; one key is public, another key is private. *** All your data and files were encrypted by the means of the public key, which you received over the web. *** In order to decrypt your data and gain access to your computer you need a private key and a decryption software, which can be found on one of our secret servers. What should you do next? There are several options for you to consider: 1. You can wait for a while until the price of a private key will raise, so you will have to pay twice as much to access your files or 2.
