![]() ![]() Currently, there are no tools capable of restoring files encrypted with such a strong algorithm. In doing so, you will support their malicious businesses and lose your money. Therefore, attempting to contact these persons or paying the ransom is risky. Be aware, however, that cyber criminals often ignore victims despite payments made. The ransom-demand message encourages users to install Tor browser, visit the URL address provided, and follow the payment instructions provided on the site. If the ransom is not paid within the given time frame, the size doubles to 2.4 Bitcoin. To receive the private key (or rather, a decryption tool with an embedded private key), payment of 1.2 Bitcoin (price of 1 Bitcoin is currently ~$646.04) must be made. ![]() Cyber criminals attempt to sell this key to victims. The private key is stored on remote servers controlled by cyber criminals - it is impossible to restore encrypted files without this key. Therefore, public (encryption) and private (decryption) keys are generating during the encryption process. As mentioned previously, Microsoft Decryptor employs an asymmetric encryption algorithm. They provide detailed information on how files have been encrypted and what victims should do to restore them. The three created files contain an identical message informing users of the encryption. ![]() html), placing them in each folder that contains encrypted files. Unlike other ransomware, Microsoft Decryptor does not append the names of encrypted files with any extension.įollowing successful encryption, Microsoft Decryptor creates three files ( README.txt, README. Microsoft Decryptor encrypts files using the asymmetric RSA4096 encryption algorithm. Microsoft Decryptor is an updated version of the CryptXXX and UltraCrypter viruses.
