I am receiving emails to my website email. I seriously doubt that the person sending the emails are sending them for genuine interest. It sounds to me that it is a hacker trying to get some information about me or my ip address or something as such for hacking person.
my question is: what could a hacker achieve by sending me an email with no attachments assuming I do reply to his email? How could I make sure I am 100% safe from any site hacking attempts?
