Data Exposed
MasTec, Inc. was the subject of a data breach notification filed with the TX Attorney General. The AG filing was recorded on June 9, 2026. The breach or discovery date reported in the filing is August 9, 2025.
MasTec, Inc. operates as a major infrastructure construction and engineering contractor, delivering comprehensive project services across the energy, communications, and utility sectors. Because of its large-scale operations, extensive workforce, and nationwide project portfolio, MasTec routinely collects, processes, and stores vast quantities of sensitive personally identifiable information. This repository typically includes comprehensive employee records, subcontractor details, payroll metrics, tax documentation, and proprietary corporate data necessary for managing thousands of personnel deployed across complex, highly regulated job sites. In 2026, MasTec reported a significant cybersecurity incident to the Texas Attorney General, signaling a breach of corporate networks that house sensitive stakeholder and employee data. Incidents affecting infrastructure and heavy-construction contractors frequently involve sophisticated external network compromises, credential harvesting, ransomware deployment, or unauthorized exploitation of third-party vendor systems. Because contractor networks often interface with diverse project management platforms and remote operational environments, threat actors actively target these digital perimeters to intercept confidential corporate and personal files. The exposure resulting from the MasTec data breach involves high-risk data categories, including full names, Social Security numbers, dates of birth, banking and direct deposit details, and confidential tax documentation. The compromise of Social Security numbers and financial account information exposes affected individuals to severe, long-term risks of identity theft, fraudulent credit applications, unauthorized bank withdrawals, and targeted phishing attacks. When primary identification credentials and payroll records are leaked into unauthorized hands, victims face persistent threats to their financial security that often require years of costly monitoring to mitigate. As an entity entrusted with sensitive employee and stakeholder records, MasTec, Inc. was legally obligated to implement and maintain robust administrative, technical, and physical safeguards to secure its data repositories. Under state data protection statutes, including the Texas Identity Theft Enforcement and Protection Act, companies handling sensitive personal information must employ reasonable security practices to thwart unauthorized access. The occurrence of a widespread data breach strongly indicates potential failures in network segmentation, vulnerability management, multi-factor authentication enforcement, or rapid incident detection protocols. Receiving a data breach notification letter from MasTec serves as formal acknowledgment that your private information was compromised due to inadequate security measures, establishing legal standing to participate in a class action lawsuit. Affected individuals do not need to prove that financial loss has already occurred to seek legal recourse and hold the company accountable. Our law firm is actively investigating potential class action claims on a contingency fee basis, meaning there are never any out-of-pocket costs or attorney fees unless we successfully recover compensation on your behalf.
Based on the data types reported, affected individuals face:
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.
Phone numbers exposed in breaches are used for SIM swapping attacks — hijacking your number to bypass two-factor authentication on financial accounts.
What the Texas Identity Theft Enforcement and Protection Act and federal statutes entitle you to recover:
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.
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.
No. Under Texas Identity Theft Enforcement and Protection Act 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 MasTec, 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 MasTec, Inc. during the relevant period, you may still qualify even without receiving a letter. A free eligibility review can confirm your status.
