Check My Rights →Lang Management Company, Inc. was responsible for safeguarding the personal data of its customers and employees. According to a MA state filing, Lang Management Company, Inc. experienced a data security incident affecting an undisclosed number of individuals, exposing financial account information and payment data. Legal proceedings relating to this breach are ongoing.
Lang Management Company, Inc. was required under the Massachusetts Data Security Law (201 CMR 17.00) to implement reasonable security measures to protect the personal information it collected. When those measures fail and personal data is exposed to unauthorized parties, the law provides remedies for affected individuals — regardless of whether those individuals have yet experienced fraud or identity theft as a direct result.
Lang Management Company, Inc. appears to operate as a professional property management firm, typically overseeing residential and commercial real estate properties. In the regular course of business, companies in this sector collect and store sensitive personal and financial data from tenants, homeowners, and employees, including names, Social Security numbers, banking details, and residential addresses. This security incident was officially reported to the Massachusetts Attorney General in 2025. Individuals whose personal information may have been compromised during the incident were sent a formal data breach notification letter via mail. If you received one of these letters, it indicates that your personal data was stored within the environment affected by the security event, prompting the company to advise you to monitor your accounts closely.
Based on the data types reported in this filing, affected individuals face the following specific risks:
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.
Home address exposure can enable mail theft, package fraud, and targeted phishing attacks that reference your known location.
Combined with a name and other leaked data, date of birth helps criminals pass identity verification questions at banks and government agencies.
Under the Massachusetts Data Security Law (201 CMR 17.00), you may have a legal claim against Lang Management Company, Inc. if any of the following apply:
Applicable law: This breach was reported under the Massachusetts Data Security Law (201 CMR 17.00), which establishes your right to seek damages from Lang Management Company, Inc..
The hours spent responding to a data breach — canceling accounts, contacting credit bureaus, updating passwords, and investigating fraud — represent compensable economic harm in data breach litigation.
Once your SSN is exposed, protection becomes an ongoing expense. Plaintiffs in data breach settlements have recovered costs for credit freezes, identity protection subscriptions, and time spent dealing with fraudulent accounts — sometimes covering multiple years of exposure.
Fees charged to close and reopen accounts, issue replacement cards, or dispute fraudulent transactions are recoverable in data breach litigation. So are the costs of overdrafts, late payments, and credit damage caused by unauthorized activity.
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 Massachusetts Data Security Law (201 CMR 17.00) 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.
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.
Accepting free credit monitoring from Lang Management Company, Inc. 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 Lang Management Company, Inc. during the relevant period, you may still qualify even without receiving a letter. A free eligibility review can confirm your status.
