I'm imagining bank account numbers over CC info/passwords was the sensitive part.

Bank account numbers are not secret. If you write a check to someone they have your account number.

Well they are in this weird space of being able to be used to pull money from the account though ACH/demand drafts, so they _should_ be secret, but then as you said they are on the bottom of every check. Which is super weird, and not the case in other countries' banking systems.
