Executive Summary

Neiman Marcus suffered a data breach affecting 31.2 million customers after attackers gained unauthorized access to the company's Snowflake cloud storage account between April 14 and May 24, 2024. The breach was part of a wider campaign targeting Snowflake, a cloud data platform, that compromised 165 organizations worldwide. Stolen data was later posted to a public hacking forum. Lawsuits filed against Neiman Marcus allege the company had not enabled multi-factor authentication on its Snowflake account, leaving it protected by a single password. The exposed data includes names, email addresses, phone numbers, dates of birth, physical addresses, IP addresses, purchase history, and partial credit card numbers. While the partial card data alone is not sufficient to make purchases, the combination of records creates a detailed profile of each affected customer. Because Neiman Marcus serves an affluent clientele, this profile is particularly attractive to fraudsters. Affected individuals face elevated risk of targeted phishing emails, impersonation scams, and fraud schemes designed to exploit both their personal details and their association with a luxury brand. Neiman Marcus began notifying affected customers around June 24, 2024. Class-action lawsuits were consolidated into multidistrict proceedings in the District of Montana as part of the broader Snowflake breach litigation. In May 2025, Neiman Marcus sought court approval of a $3.5 million settlement covering all U.S. residents whose data was potentially compromised, offering up to $2,500 in reimbursement for documented losses and two years of free credit monitoring. Affected individuals should remain alert to unsolicited contact referencing their purchases or personal details, and consider monitoring their financial accounts and credit reports closely.

ObscureIQ assessment: High risk of phishing, fraud, delivery impersonation, and affluent-target targeting. Premium-brand customer data is especially useful for scams aimed at higher-net-worth individuals.
