The Illinois Department of Healthcare and Family Services (HFS) and the Illinois Department of Human Services (IDHS) are notifying the public of an incident within the State of Illinois Application for Benefits Eligibility (ABE) system’s Manage My Case(MMC) portal.
The ABE system is the eligibility system for Medicaid, SNAP food benefits, and Temporary Assistance for Needy Families (TANF). The MMC portal within ABE enables Departments’ customers to see their case history and benefit details, as well as change account and benefit information. On March 13th, the Departments discovered suspicious user accounts had been created within the ABE system. These suspicious accounts were able to link to existing customer MMC accounts by providing the customer’s date of birth and Individual ID or Social Security Number, and then correctly answering several identity proofing questions. The Departments believe customer personal information had been stolen elsewhere – through no fault of the Departments – and this stolen personal information was then used to access customer MMC accounts.
In response to this incident, the Departments deployed a new software to stop the creation of more suspicious user accounts and de-linked the suspicious accounts from the customer accounts. The Departments notified the potentially affected individuals, the members of the Illinois General Assembly and the Office of the Illinois Attorney General today.
The Departments are providing a dedicated phone line to provide assistance and answer customer questions about this incident. Individuals with a question about this incident can call 1-877-657-0006. The assistance line is available until August 14th. Potentially affected individuals can also contact consumer reporting agencies to place a free fraud alert or security freeze on their accounts, or the Federal Trade Commission to learn more about fraud alerts, credit freezes, or other identity theft resources.
