In October 2018, GoldSilver, a bullion education and dealer services site, allegedly suffered a data breach that exposed 243,000 unique email addresses belonging to customers and mailing list subscribers. The incident reportedly included extensive personal information such as names, addresses, phone numbers, purchase histories, and passwords with answers to security questions stored as MD5 hashes. In some cases, passport details, social security numbers, and partial credit card data were also exposed.
