HIBP notifies 57 million people of Hot Topic data breach

Have I Been Pwned and third-party researchers report an alleged Hot Topic breach exposing tens of millions of customer records (names, emails, DoBs, phone numbers, addresses, purchase history, and partially encrypted credit card data). A threat actor named "Satanic" posted the data for sale and demanded ransom on BreachForums; analysts suggest an information-stealer malware infection may have harvested credentials for a data unification service, and the dataset is being actively traded while Hot Topic has not publicly confirmed the incident.
