We had an intrusion at our corporate level (for which there are 3 affiliates - 1 each in DC, Virginia, and Maryland). Residents received the required notice. The CIO's office has an ongoing contract with a computer security firm to provide security advice and help respond to incidents. To the best of my knowledge, they never conclusively determined what, if any, data was accessed. There has been little indication of harm caused.
