If SM Entertainment had your data

Look for SM Entertainment’s own notice or letter: it should say what of yours was involved. Keep it.
Call your bank on the number printed on your card (never one from a message), check recent payments and ask for a new card.
Your phone number is out: ask your mobile operator for a PIN or port-out lock, so nobody can move your number to another SIM card and take your login codes.
Your home address is out: be wary of letters, parcels or visitors that mention SM Entertainment, and of texts asking for a “delivery fee”.
Expect scams that use your details: calls, texts or emails pretending to be SM Entertainment, your bank or the police. Never give codes or passwords, never approve a sign-in you did not start, never move money.
