The GUI welcomes users and informs their files have been encrypted with a hybrid RSA-2048 algorithm. Most likely, all of their files contain .thundercrypt file extension. It follows the manner of CryptoLocker which included an elapsing clock to urge victims pay a ransom. This ransomware demands 0.345 (590.49 USD) bitcoin in exchange to the files. Furthermore, it urges victims to pay the ransom within the indicated time. Otherwise, the encrypted files will be deleted. It is a common strategy to exert psychological pressure on victims, but we do not recommend complying with the demands. In order to encourage netizens to pay the ransom, the felons offer to decrypt one file for free. Some users report that the function to display encrypted files does not work. Thus, is not recommended to follow the demands but instead proceed to the eradication. Do not waste time and remove Thundercrypt as soon as possible.
