Your SSN is the master key to your identity. Once exposed, criminals can open new lines of credit, take out loans, or file taxes in your name.
Combined with a name and other leaked data, date of birth helps criminals pass identity verification questions at banks and government agencies.
Home address exposure can enable mail theft, package fraud, and targeted phishing attacks that reference your known location.
Under the Illinois Personal Information Protection Act (PIPA), you may have a legal claim if:
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.
Professional credit monitoring services cost $10–$40 per month. Identity theft restoration services, if needed, can cost hundreds of hours and thousands of dollars. Courts have awarded these costs as direct damages in SSN breach cases.
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.
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.
No. Under Illinois Personal Information Protection Act (PIPA) 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.
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.
Immediately place a free credit freeze at all three bureaus (Equifax, Experian, TransUnion). A freeze blocks new accounts from being opened in your name. Then file a complaint with the FTC at IdentityTheft.gov and contact our office — SSN exposure is one of the most serious breach types.
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.
State statutes of limitations for data breach claims typically run 2–4 years from the date of the breach or its discovery. Because this breach was recently disclosed, the window is open — but acting early preserves your options and strengthens the case.
Accepting free credit monitoring from Stephen Mathias & Co 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.
Not necessarily. Many data breach victims are never notified directly. If your personal information was held by Stephen Mathias & Co during the relevant period, you may still qualify even without receiving a letter. A free eligibility review can confirm your status.
Join the class action and seek compensation for your exposure.
