What Happened?

According to a notice filed with the California Attorney General, MES detected suspicious activity in its network on or around July 22, 2025. An internal investigation confirmed that an unauthorized party accessed—and likely exfiltrated—files containing personal information.

MES completed its file review on August 20, 2025. While the company has not yet publicly detailed the exact data types exposed, California law defines “personal information” broadly. Potentially compromised data can include:

  • Full name
  • Social Security number
  • Driver’s license or state ID number
  • Financial account details and access codes
  • Biometric or genetic data
  • Health or medical information

When Were Victims Notified?

MES began mailing individualized breach letters on September 12, 2025. The correspondence outlines exactly what information was impacted for each recipient and offers complimentary credit monitoring services.
