内布拉斯加州北普拉特市遭网络攻击：州长宣布紧急状态，国民警卫队网络小组驰援
内布拉斯加州州长吉姆·皮伦（Jim Pillen）10月9日签署紧急公告，应对影响林肯县（Lincoln County）与北普拉特市（North Platte）的网络安全事件。公告授权州副官长调动内布拉斯加国民警卫队网络保护小组（Cyber Protection Team），支援地方政府处置此次事件。
"这支队伍拥有应对此类情况的知识与专业训练。他们随时待命，支援我们地方县市官员查明此次中断的原因并采取必要的补救措施。"皮伦在声明中说。内布拉斯加州应急管理署（NEMA）正在协调州与地方合作伙伴支援响应，并根据事态发展持续提供资源与专业支持。
据内布拉斯加州州长办公室发布的新闻稿，此次入侵已被控制，但电话与互联网服务中断仍在持续：市政府部分电话线路与林肯县全部电话线路中断；北普拉特公共安全大楼的电话保持畅通，林肯县警长办公室的电话则无法接通。官员强调，911 等紧急服务保持正常运行；水电等公用事业、账单支付与财务系统未受影响，市县财政资金安全；公告发布时尚未发现信息泄露。公共交通照常运营，其总机已转接至手机。官员请公众在服务中断期间保持耐心。
公告授权部署国民警卫队网络保护小组协助地方官员，但授权本身并不等于小组已经进驻。州与私营部门的网络安全专家已参与响应。官员表示，只有在调查确认不存在残留入侵、城市与县系统安全之后，受影响系统才会恢复，服务恢复正常时将另行公告。
北普拉特是林肯县县治，位于内布拉斯加州西部。此次州长动用国民警卫队网络力量支援地方政府，显示事件已超出市县自身技术处置能力。网络攻击导致地方政府电话系统瘫痪、警长办公室失联，也再次凸显美国中小城市关键基础设施在网络安全上的脆弱性。
Cyberattack Hits North Platte, Nebraska: Governor Declares Emergency, National Guard Cyber Team Deploys
Nebraska Gov. Jim Pillen signed an emergency proclamation on Friday, October 9, following a cybersecurity incident affecting Lincoln County and the City of North Platte. The proclamation authorizes the adjutant general to deploy the Nebraska National Guard's Cyber Protection Team to support local jurisdictions in responding to the incident.
"This team has the knowledge and specialized training to deal with situations like this. They stand ready to support our local county and city officials in identifying the cause of this outage and addressing necessary remedies," Pillen said. The Nebraska Emergency Management Agency (NEMA) is coordinating with state and local partners to support the response and connect partners with resources and expertise as the situation evolves.
According to a local government press release, the breach had been contained, but disruptions to phone and internet services continued: some city phone lines and all Lincoln County phone lines were down. Phones at the North Platte Public Safety Building remained operational, while the Lincoln County Sheriff's Office phone lines were unavailable. Officials stressed that emergency services, including 911, remained operational; utility services, bill payments and financial systems were not affected, and city and county finances remained secure. No compromised information had been identified at the time of the announcement. Public transit continued operating, with its main phone line transferred to a cellphone, and officials asked the public for patience.
The authorization allows the Guard's cyber team to assist local officials but does not by itself confirm the team had already deployed. State and private-sector cybersecurity experts were assisting with the response. Officials said affected systems would be restored once investigators determined that no additional breaches remained and city and county systems were secure, with a follow-up announcement expected when services return to normal.
North Platte, the seat of Lincoln County in western Nebraska, turned to state-level cyber resources — a sign the incident exceeded local technical capacity. A cyberattack that knocks out a county's phone system and leaves the sheriff's office unreachable underscores, once again, how vulnerable the critical infrastructure of America's smaller cities remains to network intrusions.
