At first glance, the email looks like a textbook phishing attempt. Subject line: “Invoice from Help those affected by the California Wildfires. Body text: “‘Help those affected by the California Wildfires’ sent you an invoice for $35.00 USD.” A button in the email reads “View and Pay Invoice.” Who in their right mind would click that?
In fact, the email really is from PayPal (firstname.lastname@example.org) and there really is an invoice waiting for you in your PayPal dashboard. The transfer is already pending, even if you never clicked that dreaded button.
