Case notes

Barnes Dennig, an organization operating in Indiana, has reported a data security incident that impacted personal information. The breach was discovered on March 27, 2025, prompting an immediate internal investigation into the nature and scope of the event.

The company officially filed notification of this security incident on August 4, 2025, making the information available through public records. At present, the investigation into what specific information was involved and the full extent of the impact is ongoing, according to the filing.

Because the investigation is still in progress and specific details about the compromised data have not been released in public filings, individuals should take general precautions. It is always wise to remain alert for any unusual activity in your personal accounts and financial statements.

Consider implementing a credit freeze or fraud alert with major credit bureaus, even if specific financial details are not confirmed to be part of this incident. Regularly review account statements for unauthorized transactions and be cautious of unsolicited communications requesting personal details.

Questions about this case file

Where does the Barnes Dennig case file come from?
Every entry is taken from the breach report Barnes Dennig lodged with the Indiana Attorney General. Nothing here is estimated.
Why do the incident date and the report date differ?
Companies usually investigate before they report. The gap between the two dates shows how long that took.
What does the records-affected figure count?
It is the number the company gave the state. It can cover residents of that state only, so the national total may be higher.
Does this case file change over time?
Yes. When a company files an update or a new state publishes its copy of the report, the dates and counts here are refreshed.
