Stanford Health Care, Stanford Medicine Partners, and Packard Children’s Health Alliance were impacted by a data breach involving the MOVEit Transfer tool. Sensitive personal data was exfiltrated during an unauthorized access event in May 2023.
Stanford Health Care’s Data Breach Investigation
Stanford Health Care, including Stanford Medicine Partners and Packard Children’s Health Alliance, recently disclosed a data breach resulting from a known vulnerability in the MOVEit Transfer software. The breach was part of a broader cybersecurity event affecting many organizations that used the MOVEit tool, developed by Progress Software.
Stanford was initially alerted to the potential issue on July 26, 2023. Though all known patches and security updates had already been installed, Stanford immediately launched a thorough investigation using third-party cybersecurity experts. Early assessments revealed no evidence of compromise. However, further analysis uncovered that a malicious actor exploited the MOVEit vulnerability and accessed Stanford’s server on May 30, 2023. During that breach, sensitive data was exfiltrated.
The organization undertook a detailed reconstruction of the impacted system and a comprehensive data review. By August 11, 2023, the investigation confirmed that specific data related to individuals had been accessed. Although there is no evidence so far that the stolen data has been misused, Stanford has taken extensive remedial steps. These include policy revisions, enhanced monitoring, and offering affected individuals credit monitoring and identity restoration services at no cost through Welltok.
In total, 1,648,848 individuals were affected by the breach—including 8 Maine residents. Despite the scale of the breach, consumer reporting agencies were not notified, as the number of affected Maine residents did not exceed 1,000.
This breach underscores the growing threat of supply chain vulnerabilities and highlights the importance of robust third-party software security practices. Stanford’s swift response illustrates a commitment to transparency and consumer protection, but those affected must remain vigilant and explore legal options to protect their rights.
