What is the West Publishing court data breach?

West Publishing Corporation, the legal research vendor that operates the C-Track case management system used by U.S. state courts, confirmed a cybersecurity breach in early September 2026 that exposed court user data from multiple state supreme courts (Wyoming News, September 2, 2026). The breach involves historical data from case management systems of the Wyoming Supreme Court, Wyoming district courts, the New Hampshire Supreme Court, and other state judicial systems that use C-Track. The exposed data includes names, addresses, and dates of birth of individuals who appeared in the affected courts between 2015 and 2025. West Publishing is offering 12 months of free credit monitoring and identity theft protection services to potentially affected individuals through CTrackNotification.com (Wyoming News, September 2, 2026).

What information was exposed in the court data breach?

The breach exposed names, addresses, and dates of birth of court users who appeared in the affected state supreme court and district court systems between 2015 and 2025 (Wyoming News, September 2, 2026). Case information and case numbers were also accessed, including the party names, docket numbers, and case types for civil, criminal, family, and probate matters. According to the New Hampshire Judicial Branch, no evidence suggests that sensitive information like Social Security numbers was exposed (WMUR, September 2, 2026). Court documents, filings, and judicial orders were not compromised. The exposed data is sufficient for identity theft risk but does not appear to include the highest-sensitivity financial data that would enable direct account takeover.

Should I enroll in the 12-month free credit monitoring?

Yes, if you received a notification from CTrackNotification.com, you should enroll in the 12-month free credit monitoring and identity theft protection service being offered by West Publishing (Wyoming News, September 2, 2026). Even if your state is not on the confirmed-affected list, anyone who has appeared in any U.S. state court that uses C-Track case management between 2015 and 2025 should consider enrolling. The breach notification process is open to the public, and West Publishing has indicated that eligibility can be verified through CTrackNotification.com regardless of which state's courts you interacted with. The free service includes credit monitoring across all three major bureaus, identity theft insurance, and recovery services in the event of confirmed identity theft.

Was West Publishing itself breached, or only its customers?

West Publishing Corporation confirmed the breach originated with C-Track, a case management software vendor, and the unauthorized access was to C-Track's systems, not West Publishing's core Westlaw legal research platform (WMUR, September 2, 2026). However, because C-Track is a West Publishing subsidiary and the case management software it provides is the data-handling system used by state supreme courts, the data exposure is functionally a West Publishing incident from the perspective of affected court users. C-Track engaged third-party cybersecurity experts, notified law enforcement, and contained the activity after discovery. The breach is unrelated to West Publishing's Westlaw platform or the Westlaw Edge product used by legal professionals for legal research.

Exposed data includes names, addresses, dates of birth, and case information for court users from 2015-2025. Social Security numbers were not exposed. West Publishing is offering 12 months of free credit monitoring and identity theft protection at CTrackNotification.com. Anyone who appeared in any U.S. state court that uses C-Track between 2015 and 2025 should consider enrolling.

What the Disclosure Says

The Wyoming Judicial Branch released its disclosure on September 2, 2026 (Wyoming News, September 2, 2026). The breach involved historical data from case management systems of the Wyoming Supreme Court and Wyoming district courts. A preliminary review of the information indicates that limited personal information, including names, addresses, and dates of birth, was compromised. To the best of the WJB's knowledge, no documents were compromised. The WJB is reviewing the information and continues to work with the vendor and applicable law enforcement agencies to assess the impact and guide future action.

The New Hampshire Judicial Branch confirmed separately that names and cases from 2002 to 2015 were accessed by an unauthorized party back in March 2026, with the breach discovered a month later (WMUR, September 2, 2026). The Judicial Branch said the case information has not been made public, and the Branch also said there is no evidence that sensitive information like Social Security numbers was exposed. The Superior and Circuit Courts in New Hampshire were not affected, as they do not use C-Track.

What Was Exposed and What Was Not

The exposed data is sufficient to enable targeted identity theft, phishing, and social engineering, but does not appear to include the highest-sensitivity financial data that would enable direct account takeover. According to the disclosure, case information and case numbers were also accessed, including the party names, docket numbers, and case types for civil, criminal, family, and probate matters (Wyoming News, September 2, 2026). Court documents, filings, and judicial orders were not compromised.

West Publishing stated that the breach has impacted several other court systems across the country in addition to Wyoming and New Hampshire, but did not name them in the public disclosure. The full scope of the breach is still under investigation as of September 10, 2026.

What West Publishing Is Offering

West Publishing Corporation has provided 12 months of free credit monitoring and identity theft protection services to those potentially affected (Wyoming News, September 2, 2026). The page CTrackNotification.com has been established to provide information about the data breach and to evaluate eligibility for credit monitoring and identity theft protection services. Eligibility can be verified through the portal regardless of which state's courts you interacted with. The free service includes credit monitoring across all three major bureaus (Equifax, Experian, TransUnion), identity theft insurance, and recovery services in the event of confirmed identity theft.

While the Wyoming Judicial Branch believes that the individuals primarily affected are those who came into contact with the district courts or Supreme Court between 2015 and 2025, individuals who have been in contact with any Wyoming district court or the Wyoming Supreme Court are invited to visit CTrackNotification.com for further information (Wyoming News, September 2, 2026). The same eligibility process applies to other state court users potentially affected by the breach.

How This Compares to Other 2026 Court Breaches

The C-Track breach is one of several 2026 incidents involving U.S. state court or judicial-branch data. Earlier in 2026, the Pennsylvania Court of Common Pleas reported unauthorized access to its online docket system, and several county-level court systems in California and Texas experienced ransomware attacks that exposed sealed and expunged records. The C-Track breach is distinctive in that it exposes a single vendor's data-handling across multiple state supreme courts, amplifying the scope.

The pattern is consistent with broader 2026 trends in vendor concentration risk: when a single SaaS provider is used by dozens of state and local government entities, a single breach exposes data at a much larger scale than the historical model of independent on-premises court systems. The SolarWinds-style supply-chain implications are significant for state governments, and the breach is likely to drive procurement-policy changes around vendor concentration in 2027.

What Affected Court Users Should Do

If you received a notification from CTrackNotification.com, enroll in the 12-month free credit monitoring immediately. Even if you did not receive a notification, anyone who has appeared in any U.S. state court that uses C-Track between 2015 and 2025 should consider visiting the portal to verify eligibility. Place a fraud alert with all three credit bureaus and consider a credit freeze if identity theft is suspected. Monitor financial account statements for unauthorized activity, and treat unsolicited phone calls, emails, or text messages claiming to be from a court or West Publishing with skepticism - the breach data is a goldmine for targeted phishing campaigns and social engineering.

Verify current breach notifications and credit monitoring enrollment on the official CTrackNotification.com portal. Court users with questions about their specific state should contact their state Judicial Branch directly.
