What Happened?
According to O’Leary-Guth Law Office, S.C.’s public notice, the firm recently experienced a network disruption affecting limited systems. The notice says the firm isolated and secured its network and engaged third-party specialists to investigate the nature and scope of the activity. That investigation reportedly found that certain data in the network may have been subject to unauthorized access or acquisition. The same notice says the firm then worked to identify the information at risk, determine which individuals may have been affected, and validate those findings before providing notification.
The firm also states that it reviewed its safeguards, confirmed they met or exceeded industry standards, and continued taking steps to enhance security. The notice further says the firm had no reason to believe the information had been or would be misused, but encouraged individuals to remain vigilant.
What Information Was Exposed?
Based on the public notice, the categories of information potentially involved vary from person to person. The firm says the data may have included one or more of the following: name and Social Security number, government-issued identification number, financial account information, medical information, and health insurance information.
That combination matters because it could create risks beyond ordinary spam or phishing. Social Security numbers and financial account details may increase the risk of identity theft or account fraud, while medical or health insurance information can create separate privacy and insurance-related concerns. Even when misuse has not been identified, it is reasonable to monitor bank activity, credit reports, explanation-of-benefits statements, and unfamiliar mail or calls that seek personal information.
What Should You Do Next?
- Read any notice you received carefully. Save the letter or email, note any deadlines, and keep the engagement number if one was provided.
- Enroll in complimentary credit monitoring if offered. If O’Leary-Guth provided a free monitoring option, consider signing up before the enrollment period closes.
- Review your financial accounts and credit reports. Look for unfamiliar charges, new accounts, or credit inquiries you do not recognize.
- Consider a fraud alert or credit freeze. A fraud alert can add a verification step for new credit, while a credit freeze can restrict new credit from being opened in your name.
- Watch for medical or insurance irregularities. Review medical bills, insurer statements, and benefit explanations for services or claims you do not recognize.
- Document problems promptly. If you notice suspicious activity, keep records of charges, correspondence, time spent, and any out-of-pocket costs.
- Use the contact options listed in the notice if needed. The public notice lists a call center at (833) 931-5437 for questions.
