Account takeover notice

Sam's Club notified members of unauthorized access to their accounts. The filing says: “Instead, it is likely that your credentials were taken from another source, for example another company’s website, where you may have used the same or similar login information.”

Sam's Club notified affected individuals in Delaware and other states that an unauthorized party used stolen login credentials (likely from a third-party source) to access accounts in mid-September 2020. The incident involved access to names, addresses, and Cash Rewards balances. Sam's Club reset passwords, issued new membership numbers, and offered one year of free credit monitoring via Experian.
