What to do
- Change the password on that service, and anywhere you used the same password. A password manager makes this painless.
- Turn on two-factor sign-in on that service and on your email.
- Warn staff: emails, texts or calls quoting leaked details are not proof the sender is genuine.
- If card or bank details leaked, watch statements and tell the bank; if identity documents leaked, consider a credit ban or alert.
