"While no HHS systems or networks were compromised, attackers gained access to data by exploiting the vulnerability in the MOVEit Transfer software of third-party vendors," a health department official familiar with the matter said.
Hackers behind the massive breach also claimed credit for stealing data from two major law firms, Kirkland & Ellis LLP and K&L Gates LLP.
Kirkland and K&L did not immediately return messages left after hours.
