Background

What happened

According to a Notice of Data Event filed with the California Attorney General, an unauthorized actor gained access to a third-party hosted Corporation Service Company database between August 10 and August 25, 2025 and copied certain files. CSC states that it took steps to secure the network after learning of the suspicious activity and engaged third-party forensic specialists to investigate what happened and what information was involved. The public notice does not identify the actor, the vulnerability that was used, or the date CSC first detected the activity.

CSC completed its comprehensive review of the affected files on July 15, 2026 and mailed notification letters dated August 13, 2026, close to a year after the access window closed. Related filings were submitted to the Massachusetts Attorney General on August 13, 2026, reporting 500 state residents, and to the Texas Attorney General on August 14, 2026, reporting 2,481 state residents, with 2,981 individuals reported affected in total. The company is offering 12 months of single-bureau credit monitoring, credit reports, and credit scores through Cyberscout, a TransUnion company, at no cost, with enrollment required within 90 days of the notice.

The categories of information involved vary by individual and by state filing, and may include full name, date of birth, Social Security number, driver's license or state identification number, other government-issued identification number such as a passport number, and financial account or payment card number. The California sample notice does not itemize the data elements, so recipients should review their own letters to confirm which elements apply to them. Where Social Security numbers and financial account numbers are involved, the risk of identity theft and account fraud can persist for years, well beyond the 12 months of monitoring being offered.

Action plan

What to do if you received a letter

1

Keep your notice letter

Do not discard it. Your letter contains the enrollment code for the Cyberscout credit monitoring offer and is important evidence if you decide to participate in a lawsuit.

2

Enroll in the free 12-month credit monitoring

Enroll in the Cyberscout (single bureau, TransUnion) monitoring offered in your letter within 90 days of the notice date. Accepting this benefit does not waive your right to pursue legal action.

3

Place a fraud alert or credit freeze

Contact Equifax, Experian, and TransUnion to place a fraud alert or freeze on your file. Request a free weekly credit report from AnnualCreditReport.com, and use the FTC's IdentityTheft.gov recovery guide. Because Social Security numbers and government-issued identification numbers may be involved, also watch for tax returns filed in your name, unemployment or benefit claims you did not file, and new credit accounts you did not open.

Identity theft & fraud losses

Unreimbursed funds stolen from accounts, unauthorized credit lines, fraudulent tax filings, or tax refund fraud tied to the breach.

Statutory damages

Injunctive relief

FAQ

Common questions

I received a data breach letter from CSC. What should I do? +

Keep the letter, it is your proof of notice and it carries your enrollment code. Enroll in the 12 months of free Cyberscout credit monitoring within the 90-day window, review your bank, card, and credit union statements for charges you do not recognize, and consider placing a free fraud alert or credit freeze with Equifax, Experian, and TransUnion. Because the reported data may include Social Security numbers and government-issued identification numbers, also watch for tax returns or benefit claims filed in your name. A data breach attorney can review your letter at no cost and explain your options.

Am I eligible to join a class action against CSC? +

If you received a CSC notice letter dated August 13, 2026, you were among the 2,981 individuals CSC identified as affected and you may qualify. Eligibility usually turns on your state of residence, the specific categories of information involved in your letter, and whether you can document out-of-pocket costs, fraudulent charges, or time spent responding to the incident. Enrolling in the free credit monitoring does not affect your right to pursue a claim.

How much money could I receive from a class action lawsuit? +

Data breach class action recoveries vary significantly. Settlements typically range from a few hundred dollars for basic out-of-pocket losses to several thousand dollars for documented identity theft, with class size, damages, and negotiation all affecting the final amount. No payout is guaranteed, and this investigation has not yet resulted in a settlement.

What personal information was exposed in the breach? +

The California sample notice confirms that files were copied but does not itemize the data elements. Based on the state filings and the nature of CSC's business, the information may have included full name, date of birth, Social Security number, driver's license or state identification number, other government-issued identification number such as a passport number, and financial account or payment card number. The elements vary by individual, so check your own letter to confirm what applies to you.

Did CSC offer free credit monitoring? +

Yes. CSC is offering 12 months of single-bureau credit monitoring, plus credit reports and credit scores, through Cyberscout, a TransUnion company, at no cost. The notice directs recipients to enroll within 90 days of the notice date using the code in the letter. Accepting the monitoring does not waive any legal claim you may have.

How many people were affected by the CSC breach? +

CSC reported 2,981 individuals affected in total, including 500 Massachusetts residents and 2,481 Texas residents in the filings made with those states. The California sample notice does not state a company-wide figure. This page will be updated if additional state filings or court records disclose a different count.

Is there a deadline to take legal action? +

Yes. Statutes of limitations for data breach claims vary by state and legal theory, typically ranging from one to six years. Waiting can permanently bar your claim. Contact us as soon as possible for a free evaluation.

How do I get a copy of the official breach notice? +

CSC's Notice of Data Event is posted on the California Attorney General's data breach notification portal and can be downloaded there as a PDF. The Massachusetts and Texas Attorney General filings are also public. If you cannot locate your copy, Dapeer Law can help you obtain the notice during a free consultation.
