Look for Sony Network Communications’s own notice or letter: it should say what of yours was involved. Keep it.
Change your Sony Network Communications password, and the same password anywhere else you use it. Turn on two-step sign-in.
Call your bank on the number printed on your card (never one from a message), check recent payments and ask for a new card.
Expect scams that use your details: calls, texts or emails pretending to be Sony Network Communications, your bank or the police. Never give codes or passwords, never approve a sign-in you did not start, never move money.
