INCIDENT: Largest Building Material Producer Attacked by Black Basta Ransomware Group

The Knauf Group ransomware attack took place on June 29, 2022. The incident resulted in emails as well product-ordering software being taken offline, the company said in a series of updates for customers.

As ever, the extent of the compromise was hard to ascertain from the outside, with systems being rapidly shut down in the wake of the attack in a bid to contain its impact: “Many of our systems and email communication are fully functional again, other areas are currently being restarted” it said on July 20, but was still directing customers to rapidly spun up alternative PDF forms for product orders as The Stack published on July 20.

The incident could not have come at a worse time for a construction industry already embattled by supply chain issues and rampant inflation in the wake of the pandemic, which caused raw material shortages for a huge range of construction materials – plasterboard prices were reported as set to soar up to 25% in July '22.
