On April 21, 2026, Australian home builder Champion Homes appeared on the leak site of the ransomware group known as thegentlemen. The company, which has built thousands of homes across Greater Sydney and the Illawarra region since 1998, is claimed to have had internal files exfiltrated during a ransomware attack. Public reporting indicates that customer and employee records may have been among the stolen data, although the exact number of affected individuals remains unknown.

Reported Details of the Breach
Available reporting describes the incident as a classic ransomware operation. The attackers gained access to Champion Homes’ systems, encrypted data, and then exfiltrated files before demanding payment. When the ransom was not paid, the group published a sample of the stolen material on their leak site. Internal files were reportedly exposed, and the listing appeared on 21 April 2026. The company’s main website, championhomes.com.au, and its ZoomInfo business profile have been referenced in connection with the leak.
Champion Homes specialises in duplexes, knockdown-rebuild projects, house-and-land packages and custom 3–5 bedroom homes. Because the business collects detailed information during the building process — names, addresses, phone numbers, email addresses, financial details and site plans — the breach potentially places thousands of recent and past customers at risk.
Why This Matters for You and Your Family
If you or anyone in your household has bought or built a home with Champion Homes in the last 25 years, your personal information could now be in the hands of criminals. Addresses tied to construction projects are especially sensitive: they link directly to your family’s daily life, routines and security. A single leak like this can give attackers the starting point they need to attempt identity theft, phishing or physical targeting.
