Health plans, Medicaid, Medicare hit by massive MOVEit breach

Millions of health plan members have had their personal information, including Social Security numbers and medical history, breached in a massive attack affecting hundreds of organizations. 

MOVEit is a file-transferring application used by public and private organizations. In late May, the application was breached by Clop, a Russian-backed ransomware gang. 

MOVEit disclosed the vulnerability and deployed a patch to correct it on May 31. 

As of Aug. 24, the breach has impacted 988 organizations and over 58 million people, including hospitals, health systems and health plans, according to cybersecurity site Emsisoft.

Here are eight cases affecting payers to note. This list is not comprehensive:
