Neiman Marcus Customers Impacted by Snowflake Data Breach

Neiman Marcus confirmed that roughly 65,000 customers were impacted after an unauthorized party accessed its Snowflake-hosted database; the attacker known as "Sp1d3r" reportedly sold names, contact information, dates of birth, gift card numbers and large volumes of transaction and customer data, and the compromise is tied to a broader wave of Snowflake account breaches attributed to UNC5537, with investigators citing lack of multifactor authentication and inadequate access controls as key enablers.
