Investigation notes

Simon & Schuster LLC filed a data breach report with Indiana authorities on August 10, 2026. This report confirms an incident that occurred on April 29, 2026, impacting individuals whose personal information was involved.

The official filing does not specify the exact nature of the security event or the categories of personal information exposed. This means that while an incident has been confirmed, the full scope of what happened and what data types were compromised remains unclear from the public record.

The gap between the April 29, 2026 breach date and the August 10, 2026 filing date is over three months. This timeline raises questions about the promptness of notification and the steps taken by Simon & Schuster LLC during this period.
