How Does a Mac Ransomware Virus Encrypt Your Files
Encryption by theory is basically the process of enciphering data so that only users with access can unlock and read this data. This means that when a ransomware virus infects your Mac, it will run a set of scripts and processes that will attack the file structure of your files. Usually, there are a lot of encryption algorithms and they have evolved over the past few years, but the main ones in use by ransomware viruses are RSA (rivest-shamir adleman) and AES(advanced encryption standard) algorithms. They aim to either overwrite the file or delete it and create it’s encrypted copy on the victim’s compuer. Then, the ransomware virus creates a decryption key which is either a symmetric key or a private key. The newest trend with ransomware viruses nowadays is to use combination of several encryption algorithms to make decryption this more difficult.
