根据联邦调查局（FBI）的声明以及一位了解调查情况的消息人士透露，联邦调查局已确认在用于管理窃听和情报监视令的敏感网络上发生了一起疑似网络安全事件，官员们正在努力确定该事件的严重程度。
该局在周四向美国有线电视新闻网（CNN）发表的声明中表示：“联邦调查局已识别并处理了其网络上的可疑活动，我们已动用所有技术能力进行响应。”该局拒绝进一步详细说明。
一位了解调查情况的消息人士告诉CNN，这起网络安全事件与该局用于管理窃听和外国情报监视令的数字系统有关，这是其调查工作的一部分。

消息人士称，这起最近发现的网络安全事件已促使联邦调查局和司法部中负责公民自由和国家安全的高级官员采取应对措施。
与其他主要联邦机构和企业一样，联邦调查局是黑客寻求该局持有的敏感信息时的常规目标。但该局系统被入侵的情况很少被披露。
目前尚不清楚联邦调查局最新发现的“可疑活动”是否与2024年被指称与中国情报机构有关的严重“盐台风”（Salt Typhoon）入侵事件有关。2024年，美国有线电视新闻网曾报道，疑似中国黑客渗透了私营部门通信提供商并针对国家安全网络。
目前和前任官员表示，在此次可能发生的最近入侵事件发生之际，一些当前和前任官员称，联邦调查局的网络安全响应能力有所下降，联邦调查局局长卡什·帕特尔（Kash Patel）已解雇了一些负责信息技术运营的高级官员，以及负责监督联邦调查局应对“盐台风”事件的专家。
现任和前任官员称，过去一年联邦调查局内部人员变动增加，以及更广泛的动荡，加剧了美国在挫败外国网络攻击方面面临的挑战。
美国有线电视新闻网曾在2023年报道过另一起入侵事件，该事件针对纽约联邦调查局外地办事处的一个计算机系统，该系统用于调查儿童性剥削图像，包括一个用于存储与杰弗里·爱泼斯坦（Jeffrey Epstein）调查相关图像的系统。据了解此事的人士透露。

The FBI has identified a suspected cybersecurity incident on a sensitive network used to manage wiretaps and intelligence surveillance warrants, and officials are working to determine the seriousness of the incident, according to an FBI statement and a source familiar with the investigation.
“The FBI identified and addressed suspicious activities on FBI networks, and we have leveraged all technical capabilities to respond,” the bureau said in a statement to CNN on Thursday, declining to elaborate.
A source familiar with the investigation told CNN the cybersecurity incident is related to a digital system the bureau uses to manage wiretapping and foreign intelligence surveillance warrants as part of investigations.

The recently discovered cybersecurity incident has prompted senior officials at the FBI and Justice Department focused on civil liberties and national security to respond, the source said.
Like other major federal agencies and corporations, the FBI is a regular target of hackers seeking sensitive information held by the bureau. But breaches to the bureau’s systems are rarely disclosed.
It’s not clear whether the latest “suspicious activity” uncovered by the FBI is connected to the serious Salt Typhoon breach attributed to Chinese intelligence that affected a variety of US government networks. Suspected Chinese hackers are believed to have infiltrated private sector communications providers and targeted national security networks, [CNN reported] in 2024.
The recent possible breach comes amid what some current and former officials say has been a diminishing of the FBI’s cybersecurity response capabilities, with FBI Director Kash Patel pushing out some of the senior officials overseeing the information technology operations and experts overseeing the FBI’s handling of the Salt Typhoon response.
The increased turnover in FBI ranks, and wider upheaval at the FBI in the past year, has added to challenges the US faces in thwarting foreign cyberattacks, the current and former officials say.
CNN [reported] on a separate breach in 2023 that targeted affected a computer system in the New York FBI field office used in investigations of images of child sexual exploitation, including a system used to store images from the investigation of Jeffrey Epstein, according to people briefed on the matter.
