What benefit does an attacker have from an email with no body? I received an email with the email supposedly coming from a known contact, i.e. Bob Franklin, but actually a clearly fake/ spam email address ejeyd24372.gwkrh63.com. The strange part is that there is nothing in the body of the email. I could understand if there was a malicious link, but there was nothing. What is there to gain from that? To me this says that someone has three pieces of information- my email address, his full name, and the fact that we know each other. It could be that he was compromised and they found my information on his computer, or I was compromised and they found his information on my computer.
