In a brief announcement published earlier this week, it seems Thomson Reuters only noticed the intrusion now, months after it was already over.

Here is what happened: Thomson Reuters operates a court case-management
system called C-Track. It is a tool used by different courts to manage things like cases, filings, hearings, and schedules. It is used by courts in several US states, the US Virgin Islands, as well as Ontario, Canada. On June 30, 2026, Thomson Reuters detected unauthorized activity in one of its cloud environments, prompting an investigation which later determined that an unauthorized threat actor broke in and obtained some C-Track files. This happened in March 2026.

Ontario's three Chief Justices confirmed it, as well, saying Thomson Reuters notified Ontario's Ministry of the Attorney General on July 23.

A more detailed investigation is currently underway, and all relevant authorities have been notified, it was said. At press time, Thomson Reuters did not yet determine exactly what information was accessed, or how many people were affected. The good news, however, is that there is currently no evidence of identity theft resulting from the incident, and there is no indication that systems handling court-related financial transactions were affected.

C-Track itself remains operational, as well. No threat actors have yet
claimed responsibility for the attack or threatened to leak the files to the dark web.

"There has been no operational disruption to C-Track as a result of this incident," a Thomson Reuters spokesperson said. "Our products and services remain fully operational and are safe to continue to use. Independent cybersecurity experts assisted in the investigation and validated the remediation measures implemented." Are you a pro?
