I was born dual US/Brazil and left Brazil just after turning 18 about 36 years ago, wondering wondering whether I'm in the leak and whether anyone could use my info to open illicit bank accounts, etc. I don't want to be associated with money-laundering, and am too far in headspace from financial-institutions/credit-bureaus to check it out.

If you declared permanent out-of-country move, you (or an impersonator) shouldn't be able to open accounts/buy things - as far as I know.

I think there are extra fees as a foreigner. You are not prohibited of having a bank account, insurance, using credit, etc. But most systems will prevent the CPF of being used without some sort of special approval.
