New Hampshire Supreme Court

An unauthorized user reached names and addresses tied to New Hampshire cases filed between 2002 and 2015, sitting inside C-Track, the case management platform that West Publishing, a subsidiary of Thomson Reuters, runs for court systems across 11 states, Canada, and the Virgin Islands. The source names no entry point and no actor, only a March 2026 intrusion found on June 30. One vendor's platform became the shared perimeter for a dozen separate judiciaries. The exposure lived entirely inside West Publishing's own database, walled off from the other judicial branch's systems that were never touched.
