The Nightspire ransomware group listed KSL Dirtworks LLC on its leak site on or about July 27, 2026. The group claimed to have exfiltrated approximately 150 GB of data from the company.
The exposed data types reportedly include HR documents, financial documents, contracts, bids and proposals, project documents, office documents, construction standards, and insurance documents. While financial documents are noted, the presence of specific SSNs or medical data has not been confirmed. The total number of affected individuals has not been disclosed, and no specific states affected have been identified.
No official breach notification, state attorney general filing, or confirmed victim count from KSL Dirtworks LLC was found in the provided sources. Details regarding consumer notification and any potential class action litigation remain unknown. Information regarding company revenue and whether the company is publicly traded is also unavailable. KSL Dirtworks LLC appears to be the direct victim, not a third-party vendor in a larger breach incident.
