CARY – Cornerstone Building Brands, one of the largest manufacturers of exterior building products in North America, was the target of a ransomware attack impacting certain of its operational and information technology systems.

The Cary-based firm, with more than $1 billion in annual revenue, detected the attack on August 9, according to a securities filing.

Promptly upon its detection of the attack, the company said it launched an investigation, notified law enforcement and engaged the services of specialized legal counsel and other incident response professionals.

To date, the company said it has recovered many of its critical operational data and business systems.

“Although the Company is in the early stages of assessing the incident, based on the information currently known, the Company does not expect the incident to have a material impact on its business, operations or financial condition,” it said in the filing.

In November 2018, NCI Building Systems merged with Ply Gem Parent to form Cornerstone Building Brands. It has expansive national footprint that includes approximately 20,000 employees at manufacturing, distribution and office locations throughout North America.

The company added it carries insurance, including cyber insurance, “which it believes to be commensurate with its size and the nature of its operations.”

That’s a must these days for companies considering that cybercrimes are surging, according to a new report from Infosys.

The tech and security firm finds that cyberattacks have surged 400 percent as the pandemic has driven workers from office networks to distributed connections.

IBM reported similar findings in its own recent security report.
