If I was the attacker, I'd use credential-stuffing or something to get access to some random employee's account. Doesn't have to be anyone important.

Then I'd set up a short-notice multi-way meeting between the target, the CEO and the hacked account. The deepfake 'CEO' then turns up with no alarms raised, except one wrong name - easily dismissed as a glitch, or an assistant having booked the meeting.

So your method assumes you can easily take over an employee account? Isn't that the hard part?

Employees are typically the weak point in corporate security.

$10k/week in crypto lets you easily 'hack' a random corporate account

But that CEO account would be marked as (guest/unverified) in Teams or Zoom.
