You open the practice's attachments before anyone else
The front office's generic mailbox receives everything: laboratory reports, letters from colleagues, supplier invoices, unsolicited job applications, reminders from health insurers. Nobody in the practice opens as many files from outside, and nobody has as many legitimate reasons to do so. That is what makes it the entry point attacks use most. The course does not ask you to stop opening attachments, which would be absurd, but gives a check that takes a few seconds: is the sender who they claim to be, does the message match an ongoing exchange, does the attachment have the expected format.
