If credit card data is affected, the agency advises users to contact the card company and check statements for unauthorized charges.
IPA also warns that leaked email addresses, phone numbers, addresses and names may be used for phishing emails, SMS messages and scam calls.

For prevention, the agency recommends long, complex passwords that are not reused, along with multi-factor authentication or passkeys where services offer them. It also advises limiting the personal information registered with each service to the minimum necessary.
