U.S. consulting firm Greylock McKinnon Associates (GMA) disclosed a data breach in which hackers stole as many as 341,650 Social Security numbers.
The data breach was disclosed on Friday on Maine’s government website, where the state posts data breach notifications.
In its data breach notice sent by mail to affected victims, GMA said it was hit by an unspecified cyberattack in May 2023 and “promptly took steps to mitigate the incident.”
