Snowflake, Neiman Marcus data breach class action lawsuit overview: 

  • Who: Natalie Gianne filed a class action lawsuit against The Neiman Marcus Group LLC and Snowflake Inc. 
  • Why: Gianne claims luxury retailer Neiman Marcus and Snowflake, a cloud-based data management company, failed to safeguard the sensitive information of their customers during an April 2024 data breach involving the latter. 
  • Where: The class action lawsuit was filed in Montana federal court. 

Luxury retailer Neiman Marcus failed to safeguard the sensitive information of its customers during an April 2024 data breach involving Snowflake Inc., a cloud-based data management company.

Plaintiff Natalie Gianne claims Neiman Marcus and Snowflake failed to protect the information from a “foreseeable cyberattack” that exposed cloud-based data records belonging to Neiman Marcus and “stored with an entrusted to Snowflake.”

“Defendants’ failure to implement standard security measures was a significant factor leading to the Data Breach,” the Neiman Marcus data breach class action claims. 

Gianne wants to represent a nationwide class and California subclass of all individuals whose personally identifiable information was compromised as a result of the Snowflake data breach.

Gianne argues Snowflake did not automatically require clients to use multifactor authentication (MFA), despite “being well aware of the risks of cyberattack and data theft,” and that Neiman Marcus did not implement MFA or other standard security measures on its Snowflake account.

“By failing to implement reasonable security measures to safeguard Plaintiff’s and Class Members’ PII, Defendants breached their duty to and disregarded the rights of Plaintiff and the Class Members,” the Snowflake data breach class action says. 

Gianne claims Neiman Marcus and Snowflake are guilty of negligence and negligence per se, unjust enrichment and invasion of privacy in addition to several California consumer protection laws. The plaintiff also accuses Snowflake of breach of third-party beneficiary contract. 

The plaintiff demands a jury trial and requests declaratory and injunctive relief and an award of actual, nominal, statutory, consequential and punitive damages for herself and all class members. 

A number of other companies have recently been hit with class action lawsuits regarding data breach incidents; some of the companies facing lawsuits include Ally Financial, Acadian Ambulance, National Public Data, Cricket Wireless, Rite Aid and AT&T.
