“长时间”
用英语怎么说？

The initial breach occurred in March 2026, though Thomson Reuters did not detect any anomalous activity within its cloud environment until June 30 of the same year. Upon recognizing the breach, the company initiated an intensive forensic investigation, which eventually confirmed that an unauthorized threat actor had successfully infiltrated their cloud database and exfiltrated sensitive C-Track records. Officials in the affected jurisdictions, including three Chief Justices in Ontario, subsequently verified the security incident. The Ministry of the Attorney General in Ontario was formally notified of the breach on July 23. This extended period of undetected exposure highlights the vulnerability of critical legal infrastructure, as the adversary operated stealthily within the network for months.

最初的侵入发生于2026年3月，但汤森路透直到同年6月30日才在其云环境中检测到任何异常活动。在确认漏洞后，该公司启动了深入的法证调查，最终证实一名未授权的威胁参与者已成功渗透其云数据库并窃取了敏感的 C-Track 记录。受影响辖区的官员（包括安大略省的三位首席大法官）随后核实了该安全事件。安大略省总检察长部于7月23日正式收到该漏洞的通知。这段长时间未被发现的暴露期凸显了关键法律基础设施的脆弱性，因为对手在网络中悄悄地运行了数月。
