I've got an email that seemed genuine at first glance from my acquaintance.
It almost made me want to reply to the email asking him if he and his family are OK, but at the same time, it looked suspicious. I clicked on "show details" and had a look at the reply-to field and it confirmed my suspicion. The field is pointing to a different email address (in this case yahoo mail), which means that the email was most likely hacked, and the hacker would want me to reply to the message to confirm that my email address exists, and therefore would ask me to send some money to some overseas account.
I ignored the email and a few days later I got an email from him that his email account was hacked. It is another reminder for me that I need to be more careful before responding to any email messages.
