The trend nowadays is for crypto viruses to use a combination of both, making the direct decryption even more impossible than it was before unless you have a decryption software which is again, coded by the ransom virus authors.
After the encryption is complete the ransom virus generates a decryption key, which can be either Private(symmetric) or public. The original file is then deleted and the virus leaves the file to appear as if it is corrupt. This basically means that the virus infects your computer after which runs a set of processes which create a copy of the original file and this copy has parts of data replaces with the one from the encryption algorithm used (RSA, AES, etc.). How Does Ransomware Encrypt Data?īy default, encryption can be explained as “The process of encoding information so that only parties with access to it can read it.”, according to it. This is why, we as a security blog with extensive experience in how such viruses encrypt your data has decided to go over the main methods that you can use to restore data in the event that there is no decryptor that is officially working for the virus at hand. So with ransomware evolving, the common user does not really have the capability or the know-how on how he or she can fight back to this menace and restore files without having to go through the painstaking process of paying BitCoins.
Ransomware viruses have been around for quite some time and with most of them now decryptable the developers of viruses have “learned” their lesson and have created a much stronger encryption scripts than before. These instructions will help you, in case you don’t want to pay any ransom to cybercriminals. We have created this instructive article to explain the current options that you, as a victim, have to restore files encrypted by ransomware.
