CILLA ransomware encryption process.

The encryption process can be divided into two steps, that always occurs in the same way. At first, the CILLA scans the hard drive and looks for the appropriate files to encrypt. These files usually are all types of documents and media files, as these files in the most cases are the most important information on a hard drive and the victim is more likely to pay for the decryption services. When the files are found, CILLA begins to modify the structures of the files and as the result they get new extension “.cilla”. In order to use the decryption services that hackers provide, the virus creates the special notification. The ransoms need to assure you, that there is no any other option, but to pay them. We are to warn you, that the criminals can easily deceive you. Usually hackers ignore the victims once they get the payment, however, they can easily make everything much worse.
