Last week it was fake confirmation email of Amazon Orders. Now we have a flood of phishing spam claiming Apple Store orders. Though most should get caught by email filters, some may get through. So, as a reminder, don't be fooled.
The messages are designed to get you to worried that someone is making unauthorized purchases with your info. And there is usually a link to confirm the details of the order. When you click, you have no idea where you are going (even if it says 'apple.com' or 'amazon.com') and you can end up at a nefarious website that either installs a virus (you aren't using Internet Explorer, are you?), or the site might ask for your login info.
The choice is yours. Fall prey to the scammers, or be smart and ignore most of these emails.
