A market analysis company accidentally exposed customer data from major retailers, including Kate Spade & Co. and Beverages & More Inc., after storing the information in an Amazon Web Services cloud container, according to a new report from cybersecurity firm UpGuard.

The 747 gigabytes of data stored by Tetrad Computer Applications Inc. also included market information about millions of American households, such as where they are located and their purchasing histories, said Chris Vickery, UpGuard’s director of cyber risk research. UpGuard discovered the data Feb. 1 and worked with Tetrad to wall it off, he said.

Tetrad said in a statement that UpGuard alerted it to a default security setting that left files related to a “limited number” of its clients and suppliers exposed.
“The legal liability for a company using a cloud service that is not properly secured is immense,” McCreary said. “It is on the business to make sure proper security protocols are implemented.”

The data included a spreadsheet of more than 700,000 Kate Spade online accounts as well as information from 3.8 million BevMo loyalty cards, Vickery said. UpGuard couldn’t determine whether the data was used or taken by cybercriminals or other third parties, he said.

“The publicly exposed data here reveals which households spent a few dollars on their respective offerings and which spent tens of thousands,” Vickery said.

Tetrad’s files also included consumer profile information on many American households that was culled from database firm Experian Plc, consumer segmentation analysis company Claritas LLC, publicly available U.S. census data, and other sources, according to UpGuard’s report and screenshots reviewed by Bloomberg Law.
