Exposed Data — What's at Risk

SIM Swap & Vishingmedium risk

Phone numbers exposed in breaches are used for SIM swapping attacks — hijacking your number to bypass two-factor authentication on financial accounts.


Check Your Eligibility

Under the California Consumer Privacy Act (CCPA), you may have a legal claim if:

  • You received a written data breach notification letter from Fullsteam Software Holdings LLC d/b/a Event Rental Systems
  • You are or were a customer, patient, or employee of Fullsteam Software Holdings LLC d/b/a Event Rental Systems
  • Your information was held by Fullsteam Software Holdings LLC d/b/a Event Rental Systems in CA
  • Your bank or payment card data was potentially exposed

Rights Under the Law

Time & Inconvenience

Courts recognize that the time spent monitoring accounts, placing credit freezes, and dealing with the aftermath of a breach has real economic value. This category of damages is recoverable even without direct financial loss.

Financial Losses & Fraudulent Charges

Direct financial losses resulting from the breach — unauthorized charges, fraudulent transfers, or fees incurred through fraud — are recoverable as compensatory damages. Banks may reverse some charges; a class action recovers the remainder and associated costs.

Account Compromise Damages

When login credentials are exposed, the costs of downstream account compromises — password managers, security audits, and recovery costs for hijacked downstream accounts — can be recovered. Courts in recent class actions have awarded damages for credential exposure even without proven misuse.

Emotional Distress

Data breach victims regularly report anxiety, loss of sleep, and ongoing fear of identity theft. These non-economic harms are cognizable injuries in data breach litigation, particularly in cases involving SSN or medical record exposure.

Note: an attorney general breach filing does not by itself establish a settlement fund, a payment amount, or a claim deadline. If an official settlement notice is later issued, rely on that notice for payment details and deadlines.


Frequently Asked Questions

Do I need proof that my data was misused to file a claim against Fullsteam Software Holdings LLC d/b/a Event Rental Systems?

No. Under California Consumer Privacy Act (CCPA) and federal law, the unauthorized exposure of your personal data — regardless of whether it has been actively misused — can be sufficient grounds for a claim. The breach itself is the injury.

How much does filing a claim cost?

Nothing. The Law Office of David S. Harris handles data breach cases on contingency — you pay zero upfront and owe nothing unless compensation is recovered.

My financial account data was exposed. Can the bank recover my losses?

Banks may reverse fraudulent charges, but they are not obligated to compensate you for time lost, stress, or indirect damages. A class action claim against the breached company can recover those additional categories of harm.

Is it too late to file a claim?

Statutes of limitations for data breach claims vary by state but typically run 2–4 years. Depending on when you learned of the breach, you may still have time. Contact our office for a free eligibility review — there is no cost to find out.

What if Fullsteam Software Holdings LLC d/b/a Event Rental Systems offered me free credit monitoring after the breach?

Accepting free credit monitoring from Fullsteam Software Holdings LLC d/b/a Event Rental Systems does not waive your right to pursue legal action unless you signed a specific release waiving claims. In most cases, victims who accepted monitoring can still file.

Do I need to have received a notice letter to be eligible?

Not necessarily. Many data breach victims are never notified directly. If your personal information was held by Fullsteam Software Holdings LLC d/b/a Event Rental Systems during the relevant period, you may still qualify even without receiving a letter. A free eligibility review can confirm your status.

How long does a data breach class action lawsuit take?

Most data breach class actions resolve within 18 to 36 months, though timelines vary by court and complexity. Your participation requires minimal effort — typically completing a claim form. Our office handles all litigation; you are notified when a settlement is reached.
