We have created this instructive article to best explain the current options that you as a victim have to restore your files in case you do not wish to pay ransom to cyber-criminals.
Ransomware viruses have been around for quite some time and with most of them now decryptable the developers of viruses have “learnt” their lesson and have created a much stronger encryption scripts than before. 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 get the files back without having to go through the painstaking process of paying BitCoins. This is why, we as a security blog with extensive experience in how such viruses encrypt your files have decided to go over the main methods that you can use to restore your encrypted files in the event that there is no decryptor that is officially working for the virus at hand.
How Do Ransomware Viruses Encrypt Files?
By 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.ucsf.edu. 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 data from the encryption algorithm used (RSA, AES, etc.). The original file is then deleted and the virus leaves the file to appear as if it is corrupt. After the encryption is complete the ransomware generates a decryption key, which can be either Private(symmetric) or public. The trend nowadays is for ransomware 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 ransomware authors.
