What to do

If you have an account, change that password, and anywhere you reused it.
Turn on two-factor authentication, ideally an authenticator app or passkey, not SMS.
Expect phishing that uses your real details. Do not click links in messages about this incident; go to the company's site directly.
If payment cards were involved, watch statements and ask your bank for a new card.
If government ID or social security numbers were involved, consider a credit freeze.
