Dive Insight:

Shelby Lentz, the director of marketing communications for Simpson Strong-Tie, told Construction Dive that the company had no further information outside of what was in its SEC filing.

Simpson caters to the residential, commercial, national retail, original equipment manufacturing and building technology segments of the industry, according to its website. Last year, it had consolidated net sales of $2.12 billion, an increase of 34.5% from $1.57 billion in the previous year, according to the company’s full-year earnings report.

This is at least the second construction-related company to have a visible cybersecurity incident in recent weeks. 

Builders Mutual Insurance Co., a commercial construction underwriter based in Raleigh, North Carolina, was the target of a hack that affected the personal information of 64,761 customers, current employees and former workers. The breach was revealed in a filing with the Maine Attorney General’s office on Sept. 29.
