Stop clicking on e-mails about your package delivery! Scam, scam, scam! Look, it's simple:
This technique is called social engineering: tricking people into doing things they shouldn't. People are too quick to click. I wonder how many of these clicker-happy people ever even gave their e-mail address to UPS. The last time I sent something via UPS, I don't even recall being asked for my e-mail address.
But people so freely give out their e-mail address, that when they receive one of these phishing e-mails by crooks, they think it's legitimate. They believe that the attachment is a new shipping label to print out. They even believe the threat that if they don't use this new label right away, they'll be charged a fee. It's all about hurry, hurry, hurry! People don't stop and T-H-I-N-K first.
What can be done about this? First off, don't freely give out your e-mail. That way, if you get an e-mail from a company that you just, by chance, happen to be doing business with, you'll know it's a fraud-because you never gave your e-mail to that company in the first place.
Next, share this information with your family and friends. They'll probably all deny that they're capable of falling for this scam, but I'm sure that when the unwise ones are alone, they'll give it some hard thought.
