Amazon data center construction plans leaked

A threat actor is claiming to have breached Cooper Steel Fabricators, a major Tier-1 structural steel fabricator based in the US. A “complete mirror” of the company’s FTP server has been listed for sale.

According to the threat actor’s post on the dark web, the compromised data includes highly detailed technical documents and proprietary project information.

In fact, the actor says it had listed a “complete mirror” of Cooper Steel’s FTP server for sale. The data allegedly comprises 330GB “with no deletions or extraneous files,” and the threat actor wants a payment of $28,500 in cryptocurrency.

Cybernews has contacted Cooper Steel for more information about the alleged data theft and will update this article once a reply is received.

The allegedly compromised data includes various models, frames, and drawings of the company’s past and present projects.

For example, the threat actor claims it’s selling complete coordinated sets of architectural, structural, mechanical, and refrigeration piping drawings of the Publix Greensboro Refrigerated Distribution Center. This project was finished in 2022, though.

The listing also includes data on Cooper Steel’s role in building Amazon’s data center, located in the state of Ohio.

Amazon is pretty secretive about its infrastructure due to security concerns, but it owns dozens of data centers in the Buckeye State. The threat actor claims that the “project details potentially include structural specifications for hyperscale data center operations.”

As confirmed by Cybernews researchers, the listing also includes information about another Amazon project for which Cooper Steel was contracted to work. The firm helped build an Amazon sorting facility in Massachusetts.

Drawings, 3D models, and data related to Walmart distribution centers, cold storage facilities, and other supporting structures are also allegedly for sale.

Boasting a revenue of $593 million in 2024, Cooper Steel is known for being AISC-certified and a direct contractor for major entities. In October, the company was named America’s fourth top steel firm.
