Kiewit Corporation was the subject of a data breach notification filed with the IN Attorney General. The AG filing was recorded on August 21, 2026. The breach or discovery date reported in the filing is February 11, 2026.
From the AG filing description
Kiewit Corporation stands as one of North America's largest and most respected engineering, construction, and mining organizations. Operating across complex, high-stakes infrastructure sectors, the company manages massive enterprise operations, massive supply chains, and a vast workforce of specialized engineers, project managers, and field personnel. Because of its scale and the sensitive nature of critical infrastructure development, Kiewit maintains extensive administrative, human resources, and operational records. This includes comprehensive personnel files, payroll and compensation details, tax documentation, and background screening records for thousands of current and former employees, subcontractors, and partners. In 2026, Kiewit Corporation reported a significant data security incident to the Office of the Indiana Attorney General. While the precise mechanics of the breach are still being uncovered through ongoing forensic investigations, incidents of this magnitude within large enterprise corporations typically involve sophisticated cyberattacks, such as unauthorized network intrusions, ransomware deployments, or the compromise of third-party vendor platforms. Large contractors are frequently targeted by threat actors seeking to exploit vulnerabilities in corporate IT infrastructure, exfiltrate proprietary business intelligence, or harvest high-value employee records stored across centralized enterprise databases. The data exposed in this security failure likely includes a dangerous combination of deeply personal and financial identifiers, such as full legal names, Social Security numbers, dates of birth, home addresses, banking and direct deposit information, wage data, and tax records. The exposure of this specific category of information creates immediate and severe risks for affected individuals. Social Security numbers and dates of birth are the foundational building blocks of identity theft, enabling malicious actors to open fraudulent credit lines, secure unauthorized loans, and intercept government tax refunds. Furthermore, compromised payroll and banking details expose victims to direct financial account takeover and fraudulent wire transfers. As an enterprise employer and corporate entity operating in Indiana, Kiewit Corporation was bound by strict legal duties under state data protection laws and common law principles of negligence to safeguard the sensitive personal information entrusted to its care. These obligations require maintaining robust administrative, physical, and technical safeguards, including comprehensive network encryption, regular vulnerability assessments, robust access controls, and rapid incident response protocols. The occurrence of a data breach that compromises confidential employee and stakeholder records strongly suggests a systemic failure of these foundational security obligations, leaving the corporation vulnerable to legal accountability. Receiving a data breach notification letter from Kiewit Corporation is a formal admission that your private, highly sensitive information was compromised due to inadequate security measures. Under the law, this notification establishes your legal standing to participate in a class action lawsuit aimed at holding the company accountable for failing to protect your data. You do not need to wait until you suffer actual financial loss or identity theft to take legal action; the increased and imminent risk of future harm is sufficient. Our law firm is investigating this breach on a contingency fee basis, meaning there are never any out-of-pocket costs or fees unless we successfully recover compensation on your behalf. Given Kiewit's prominent national footprint and the immense volume of personnel data managed through its corporate hubs, this 2026 security incident represents a major breach of privacy standards within the engineering and construction sector. The sheer breadth of vulnerable data underscores the critical need for rigorous corporate accountability and robust legal remedies for all affected workers and stakeholders whose private lives have been exposed to unnecessary risk.
Based on the data types reported in this filing:
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.
You may have been affected by the Kiewit Corporation data breach if:
Common categories of compensation in data breach class actions
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.
Several state data breach laws provide for statutory minimum damages — fixed amounts recoverable per affected individual regardless of actual loss. These provisions exist specifically to make legal action viable for victims who have not yet experienced direct harm.
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.
Applicable State Law
This breach was reported under the Indiana data breach notification law, which mandates notification and establishes your right to seek damages.
No. Under Indiana data breach notification law 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 Kiewit Corporation 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 Kiewit Corporation during the relevant period, you may still qualify even without receiving a letter. A free eligibility review can confirm your status.
