What Caused the Financial Institution Service Corporation Breach?

The Financial Institution Service Corporation data breach was only recently announced, and more information is expected in the near future. However, FISC’s filing with the Attorney General of Maine provides some important information on what led up to the breach. According to this source, FISC provides data processing and services to financial institutions. In the normal course of business, FISC relies on a file-transfer application called MOVEit, which is a product of Progress Software.

On May 31, 2023, Progress made public announcements about a vulnerability within MOVEit.

Once FISC learned of the MOVEit vulnerability, the company installed all available patches and took all steps to mitigate any threat of unauthorized access. FISC also launched an investigation to determine the impact of the MOVEit vulnerability on the information stored within FISC’s MOVEit environment.

The FISC investigation confirmed that hackers exploited the MOVEit vulnerability between May 30, 2023 and May 31, 2023, removing certain data from FISC’s MOVEit server. It was later determined that some of the data consisted of confidential consumer information provided to FISC by some of the financial institutions that rely on FISC’s services.

After learning that sensitive consumer data was accessible to an unauthorized party, Financial Institution Service Corporation reviewed the compromised files to determine what information was leaked and which consumers were impacted. While the breached information varies depending on the individual, it may include your name, address, date of birth, Social Security number, driver’s license number, other government-issued identification numbers, financial account information, telephone number, and credit and/or debit card number.
