Ransomware caused American Dental Association outage, led to stolen data

The American Dental Association recently began notifying state regulators that the “cybersecurity incident” it reported in April was actually a ransomware attack, which led to the theft of member data.

On April 23, ADA first reported to its members that a cybersecurity incident was causing technical issues and other disruptions for some of its clients, including the Texas and New York Dental Associations. In response, ADA shut down and isolated all of its systems, which affected the member-only access to the ADA and Texas Dental Association websites.

TDA later confirmed the incident was definitely caused by a cyberattack deployed on April 21 and the groups were cooperating with federal authorities on a “vigorous investigation.” ADA later followed-up by stating it was also working with third-party cybersecurity specialists.

At the time, ADA responded to rumors that data was stolen ahead of the hack by the Black Basta group by stressing that “a data breach has not occurred.”
