What the filing does not say
A filing is a receipt, not a story. Indiana law requires a business that loses Hoosiers' personal data to notify the Attorney General, and the register records who filed, when, and how many people. It does not record which kinds of data were involved, how the incident happened, or which individuals were affected. The notice letter you received from Plainfield Community School Corporation is the only document that answers those questions for you.
If you got a letter from Plainfield Community School Corporation
- Read the letter for the data types. The order of everything else depends on whether it names passwords, Social Security numbers, card numbers, or medical details. Our free breach-letter reader pulls those out on your own device and never uploads the letter.
- Change any password you used with them anywhere else you used it, email account first, and turn on two-step sign-in for email and banking. See my password leaked.
- If a Social Security number was involved, freeze your credit at all three bureaus. It is free and reversible. See freeze your credit and a company lost my SSN.
- Expect the follow-on scam. Criminals read breach news too. A call, text, or email that references this incident and asks you to “verify” anything is the second attack, not help. Paste it into our screenshot checker before you answer.
