Catch of the Day: Past Due Invoice Phish
Chef’s Special: Norton Invoice Phish

Examples of clever phish that made it past my anti-spam nets and into my inbox. Some are contributed by clients or readers like you, and other reliable sources on the Internet.

You can send phishing samples to me at

My intention is to provide a warning and show current examples of phishing scams, related articles, and education about how these scams and exploits work, and how to detect them in your inbox. If the pictures are too small or extend off the page, double clicking the image will display them in a photo viewer app.

Past Due Invoice Phish

This is a very poor example of a past due  invoice email.  The sender address is questionable.  There is NO ATTACHED INVOICE.  Not even a phone number to call.

Nevertheless, past due invoice scams usually work pretty well.  This is another approach to guard against.

Norton Invoice Phish

Here we have a better example of an invoicing scam.  The sender email address is questionable, but could be plausible.  This email at least comes with a PDF document attachment

Here is the document attachment.  It claims we have paid $549.99 to renew your Norton 360 subscription.  This email  is designed to get the target excited enough to call the customer service number at the bottom of the invoice.  The helpful call center staff will help reverse these charges.  Their real goal is to get your credit card number and other personal information in order to use your information to make purchases of their own with your card.

Be careful with these fake invoice ploys.  It is ALWAYS better to check for card activity with your credit card provider directly on their web site or using the toll-free number on your credit card
