Ransom Note
C_E_R_B_E_R R_A_N_S_O_M_W_A_R_E ######################################################################### Cannot you find the files you need? Is the content of the files that you looked for not readable??? It is normal because the files' names, as well as the data in your files have been encrypted. Great! You have turned to be a part of a big community "#Cerb3r Ransomware". ######################################################################### !!! If you are reading this message it means the software "Cerber" has !!! been removed from your computer. !!! HTML instruction ("# DECRYPT MY FILES #.html") always contains a !!! working domain of your personal page! ######################################################################### What is encryption? ------------------- Encryption is a reversible modification of information for security reasons but providing full access to it for authorized users. To become an authorized user and keep the modification absolutely reversible (in other words to have a possibility to decrypt your files) you should have an individual private key. But not only it. It is required also to have the special decryption software (in your case "Cerber Decryptor" software) for safe and complete decryption of all your files and data. ######################################################################### Everything is clear for me but what should I do? ------------------------------------------------ The first step is reading these instructions to the end. Your files have been encrypted with the "Cerber Ransomware" software; the instructions ("# DECRYPT MY FILES #.html" and "# DECRYPT MY FILES #.txt") in the folders with your encrypted files are not viruses, they will help you. After reading this text the most part of people start searching in the Internet the words the "Cerber Ransomware" where they find a lot of ideas, recommendations and instructions. It is necessary to realize that we are the ones who closed the lock on your files and we are the only ones who have this secret key to open them. !!! Any attempts to return your files with the third-party tools can !!! be fatal for your encrypted files. The most part of the third-party software change data within the encrypted file to restore it but this causes damage to the files. Finally it will be impossible to decrypt your files. When you make a puzzle, but some items are lost, broken or not put in its place - the puzzle items will never match, the same way the third-party software will ruin your files completely and irreversibly. You should realize that any intervention of the third-party software to restore files encrypted with the "Cerber Ransomware" software may be fatal for your files. ######################################################################### !!! There are several plain steps to restore your files but if you do !!! not follow them we will not be able to help you, and we will not try !!! since you have read this warning already. ######################################################################### For your information the software to decrypt your files (as well as the private key provided together) are paid products. After purchase of the software package you will be able to: 1. decrypt all your files; 2. work with your documents; 3. view your photos and other media; 4. continue your usual and comfortable work at the computer.

If TOR address is not available for a long period (2-3 days) it means you are late; usually you have about 2-3 weeks after reading the instructions to restore your files. ######################################################################### Additional information: You will find the instructions for restoring your files in those folders where you have your encrypted files only. The instructions are made in two file formats - HTML and TXT for your convenience. Unfortunately antivirus companies cannot protect or restore your files but they can make the situation worse removing the instructions how to restore your encrypted files. The instructions are not viruses; they have informative nature only, so any claims on the absence of any instruction files you can send to your antivirus company. ######################################################################### Cerber Ransomware Project is not malicious and is not intended to harm a person and his/her information data. The project is created for the sole purpose of instruction regarding information security, as well as certification of antivirus software for their suitability for data protection. Together we make the Internet a better and safer place. ######################################################################### If you look through this text in the Internet and realize that something is wrong with your files but you do not have any instructions to restore your files, please, contact your antivirus support. ######################################################################### Remember that the worst situation already happened and now it depends on your determination and speed of your actions the further life of your files.
