So for the past several months, I've been getting a few spam e-mails from a few contacts (subject is their name message body is a single link). I always ignore them and delete them. I also use Windows Live Mail exclusively. Now, today, I noticed that I've become the victim of this spam e-mail attack. When looking further into it. I see that the spam is not actually sent from me, but from another address (spoofing I assume). So as harmless as it appears, they still did send out their spam email spoofing my address, but to all of my contacts (or at least many of them). I know the e-mails did not originate from my account, so I'm not too worried but I am confused as to how they have my contact's e-mails without getting accessing my e-mail account directly. Are there any explanations that would help me understand the situation better?
