This thread is very interesting. I have a doubt. I wrote a book and sent it to a specialized editor that seems to have good references to prepare it in epub form. I am sure this person is not a hacker trying to put some malware into this epub. But, of course I have not control over her computer which may use cracked editors or be full of viruses or whatever. So my question is: Is it possible that any malware infects my epub, even if the editor is not aware of it? I am confused. I know that malware can authomatically infect executable files. But epub? Is it theorically possible?
