Holy fuck this drives me insane. My company makes us do the idiotic trainings, which tell you all the "red flags" to look for.
Then the goddamn CEO sends out an empty email, with a .docx attachment, and the subject saying "urgent, open immediately"
The HR sends out suspicious looking shit all the time. The. You have Microsoft spamming you with fucking QR codes!!!
You know what needs to happen? Disable all hyperlinks in email. Make everybody copy and paste the goddamn thing. Then they have to look at the link and they have to manually paste it into the browser. Then there are no obfuscated links. Also disable HTML email, images, and most file attachments. Then there is no pixel tracking, no possibility for malicious images to be auto-loaded, and no excuse for clicking a bad link.
