  We briefly report on a successful linear program reconstruction attack
performed on a production statistical queries system and using a real dataset.
The attack was deployed in test environment in the course of the Aircloak
Challenge bug bounty program and is based on the reconstruction algorithm of
Dwork, McSherry, and Talwar. We empirically evaluate the effectiveness of the
algorithm and a related algorithm by Dinur and Nissim with various dataset
sizes, error rates, and numbers of queries in a Gaussian noise setting.
