BleepingComputer reports that the American Dental Association
was impacted by a cyberattack over the weekend, prompting the shutdown of some parts of its network.
The ADA sent emails to its members noting that some of its systems, including ADA email and Aptify, as well as its web chat and telephone lines, have been disrupted as a result of the attack on Friday.
Impacted systems were immediately taken down, with the ADA leveraging Gmail addresses while its email systems are offline. State dental associations
, including those in Florida, New York, and Virginia, have also been hit by the ADA breach.
The attack on ADA has been claimed by the newly-emergent Black Basta ransomware group, which security researcher MalwareHunterTeam revealed began exposing data claimed to have been stolen during the intrusion.
Black Basta has already exposed nearly 2.8GB of data, or 30% of stolen data from ADA, in its data leak site, with the exfiltrated files including non-disclosure agreements, W2 forms, accounting spreadsheets, and ADA member data.
