Amount
$49.5 million payment to states; Massachusetts will receive almost $900,000
Legal basis
Massachusetts Data Breach Notification Law; Massachusetts Data Security Regulations

Why the action was brought

Blackbaud’s 2020 ransomware event exposed contact and demographic information, Social Security numbers, driver’s license numbers, financial, employment and wealth information, donation history, and protected health information of millions of consumers. Blackbaud allegedly failed to implement reasonable security, remediate known gaps, and provide customers timely, complete, or accurate breach information, significantly delaying or preventing consumer notification.
