Fullsteam Software Holdings / Event Rental Systems Data Breach

If so, your sensitive personal identifiable information may have been stolen!

Fullsteam Software Holdings LLC does business as Event Rental Systems in Albuquerque, New Mexico, providing cloud-based software for party and event rental companies. In October of 2025, Event Rental Systems discovered that malicious code had been embedded in checkout modules on some of their customers’ websites. As a result, certain consumer data may have been compromised including names, contact information, and payment information. It is possible that some affected individuals may not be aware that the payment platform they used on another company’s website was provided by Event Rental Systems. Notice letters should go out to all affected individuals.

Data breaches are serious matters that can cause long term damage. Hackers break into networks so that they can steal your personal information to sell it on the dark web, commit identity theft, financial theft or other frauds.
