Understanding your DEACONESS ILLINOIS MEDICAL CENTER data breach notification letter

If a DEACONESS ILLINOIS MEDICAL CENTER letter arrived in your mailbox, here is what it means, why you received it, and the free steps you can take right now.

Why you received this letter

Deaconess Illinois Medical Center has filed a data security incident notice with regulators. This public filing indicates that personal information may have been involved in an event, and an investigation is currently underway.

What to do after the letter

  1. Confirm the notice is genuine

    A legitimate DEACONESS ILLINOIS MEDICAL CENTER notice references the specific incident reported to the IL Attorney General and describes which categories of your information were involved. Compare the letter against the public filing before acting on any links or phone numbers it contains.

  2. Keep the letter — it is your proof of connection

    The notification letter is the document that ties your personal information to this incident. Keep the original and photograph it. If you later request a case review, this letter is the strongest evidence that you were among the affected individuals.

  3. Protect your accounts and credit

    Depending on what was exposed, consider a free credit freeze with all three bureaus, new passwords for reused credentials, and monitoring of financial statements. These steps are free and do not require you to wait for anyone's permission.

  4. Check the record against the public filing
