On June 12, 2026, Cummins Inc. filed an official notice with state authorities in Indiana, reporting a data breach that occurred on March 25, 2026. This notification confirms that an incident took place, leading to the potential exposure of personal information belonging to individuals.

While the filing from Cummins Inc. does not specify the exact categories of personal information affected, nor the number of individuals impacted, recipients of breach notification letters should proceed with the understanding that their sensitive data was compromised. The lack of specific details means it is crucial for affected individuals to remain vigilant.

If you have received a data breach notification from Cummins Inc., it is important to take proactive steps.

Be wary of unsolicited communications, as scammers often target individuals whose information may have been exposed in a breach.

Individuals whose personal information was involved may have legal rights and avenues for recourse. Understanding these rights is a critical next step after receiving a breach notification.

What our attorneys examine
