Update: The Qilin ransomware operation has listed Metricon Homes as a victim on its darknet leak site, claiming to have stolen 128 gigabytes of data containing over 98,000 files from the home builder. The attack was discovered on July 24, 2025, with the estimated attack date being July 21, 2025.
The compromised data includes confidential financial documents, proprietary architectural plans, internal marketing strategies, company credits and employee details, credit card receipts, finance and HR information, profit and loss statements, and staff salary and commission rate details. The hackers have threatened to fully publish the data within seven days if their demands are not met.
“This issue was swiftly contained with the support of external experts. Metricon can confirm that there has been no impact to the safety of our operations, and construction activity has continued without interruption,” - Metricon Homes spokesperson.
Why it Matters: This attack represents a significant threat to Australia's construction sector, as Metricon's position as the country's largest home builder means the breach could expose sensitive information affecting thousands of customers, suppliers, and employees. The stolen architectural plans and financial documents could provide competitors with substantial strategic advantages while compromising customer privacy and business operations.
The incident highlights the vulnerability of critical infrastructure companies to ransomware attacks, with Qilin being identified as the third-most active ransomware group globally with 625 claimed victims since August 2022.
