MINNEAPOLIS — Cyberattackers have stolen personal medical data on 2,000 military veterans, 616 of them in Minnesota, the U.S. Veterans Administration confirmed. The information was held by a government contractor, the Detroit-based medical transcription company DBP Solutions. The theft of the encrypted data was by a “malicious party,” the VA said. The announcement confirmed that DBP has disconnected the invaded server, installed new hardware, and created new security controls. The breach affected veterans healthcare systems in Connecticut, Maine, Maryland, Minnesota and Texas.
