The CFO Clicked

A spoofed login caught real credentials — find the blast radius before payroll runs

The situation

The CFO forwarded a 'DocuSign' email twenty minutes ago asking if it was real. It wasn't — and the audit log shows she already entered her password and an MFA code on the attacker's reverse-proxy page. There's now a live session token in someone else's hands, payroll runs in three hours, and the CFO can approve wires. You need to kill the session, rotate what matters, hunt for inbox rules and OAuth grants the attacker may have planted, and decide who else got the same lure — calmly, without making the CFO feel like she's on trial.

What you'll practice

Style: Helpful, literal, eager to mark things resolved
C
Coraline Fox
CFO (the victim)
Wants: Embarrassed, worried she'll be blamed, has a board call she can't move
Style: Sharp, proud, will shut down if you scold her
