A significant cyber attack has targeted Jennings O’Donovan, an engineering firm collaborating with Ireland’s Housing Agency on a scheme to assist homeowners affected by defective concrete blocks. The breach, described as ‘concerning’ by officials, potentially exposed sensitive personal data, including addresses, contact details, and photographs of affected properties. The Housing Agency confirmed the incident was isolated to the firm and is actively working to notify impacted applicants. Charles Ward TD, a representative of the 100% Redress Party, emphasized the need for transparency, urging affected families to receive clear information about the compromised data and protective measures being implemented. The defective block issue has plagued thousands of homes, primarily in Clare, Donegal, Limerick, Mayo, and Sligo, where water-absorbing minerals in bricks have caused structural failures, necessitating demolition. The Housing Agency is coordinating with Jennings O’Donovan to investigate the breach and has informed the Data Protection Commissioner and local authorities. Affected individuals are being advised to await direct communication from the agency, as those not contacted are not impacted by the incident.
