Missouri State Government Employee Self-Service

•[ unauthorized access, forensic investigation, financial fraud prevention ]
Missouris Office of Administration temporarily shut down the Employee Self-Service portal to contain suspicious activity and support a forensic investigation. The agency said the incident was highly localized and involved 47 accounts, and that fraud protection systems detected the unauthorized activity and prevented unauthorized transactions. Reporting noted the issue centered on an unauthorized attempt to access workers deferred savings account information and that the portal remained offline while the state worked to restore service before the next pay date, with contingency plans for pay stubs and W-2 access if downtime continued.
