Thomson Reuters detected a cybersecurity incident on June 30 involving its C-Track case management platform in 11 U.S. states, the U.S. Virgin Islands and Ontario, Canada. An investigation found that unauthorized third parties obtained certain C-Track-related files in March, including some court records containing names and personal information. Thomson Reuters said it contained the activity, engaged independent cybersecurity experts, notified law enforcement and secured the C-Track environment. The company said affected customers had been notified and that its products and services remained operational. The chief justices of three Ontario courts said it remained unclear what information may have been exposed, potentially including information about people involved in court proceedings or named in court documents. Thomson Reuters Canada planned to operate a call center from September 4 to respond to inquiries.
