Kerkoporta Ransomware – Encryption
The encryption of the important files on your computer is conducted with the aid of a specific file, responsible for it. It alters not the whole file, but only a portion of it (for example, it’s header) and this may result in the file becoming to appear like it is corrupt and cannot be opened via any program. As a result from the encryption, a unique decryption key is generated. This allows for the process to be reverse-engineered and the files to be decrypted again. However, the cyber-criminals are the only ones who have this decryption key and sell it to victims for $100. The files which may be targeted by Kerkoporta ransomware are believed to be the following file types:
