I recently got an email from a friend of mine. The email was sent using his work email. The email contained a secure attachment. I looked at the email and nothing looked obviously wrong. In fact, it looked too right. There was still something off about it. I wasn't expecting anything from him. So, I picked up the phone and called him. I interrupted him in the middle of a very busy morning.
I advised what happened, and he told him that he hadn't sent it. Whew!! Glad I didn't open it!
We often talk about getting emails from people we don't know. Obviously, we are paying more attention if the email is from someone we don't know. But sometimes the threat comes from emails purportedly from our friends. Even then, if you get an unexpected email from someone you know, especially one that has an attachment, take a breath and place a call. It is always the safest thing to do. Until it is cleared, don't open it.
Aaron, the last paragraph is duplicated
