East Bay Municipal Utility District

East Bay Municipal Utility District (EBMUD) notified employees of a potential data breach involving its Marconi emergency response software. Unauthorized individuals may have accessed the third-party hosting environment (ersquared.org) between February 5, 2014, and June 4, 2018. While no evidence confirmed personal information access, employee data (name, ID, email, job title, password hash) was stored in the system. EBMUD removed the system from service, engaged MS-ISAC, and enhanced vendor security. No financial impact was disclosed.
