好的，我现在需要帮用户总结一篇文章的内容，控制在100个字以内。首先，我得仔细阅读文章，理解主要信息。 文章讲的是美国国会预算办公室（CBO）被黑客入侵。CBO发言人确认了这一事件，并说明他们正在调查，已经采取措施控制情况，并加强了安全措施。泄露的信息包括内部邮件、聊天记录以及立法者办公室和CBO研究人员之间的通信。安全研究人员怀疑黑客利用了CBO过时的Cisco防火墙，该防火墙在2024年后未更新，可能被利用了新发现的安全漏洞。 接下来，我需要提取关键点：CBO被黑、调查中、安全措施、泄露信息类型、可能的入侵方式（过时防火墙）。然后把这些信息浓缩到100字以内，确保涵盖所有重要细节。 最后，检查语言是否简洁明了，避免使用复杂的术语，确保用户能快速理解事件的核心内容。 </think> 美国国会预算办公室（CBO）遭黑客入侵，调查发现内部邮件和通信或被泄露。安全专家怀疑攻击者利用了该机构过时的Cisco防火墙漏洞。 2025-11-7 17:37:38 Author: techcrunch.com(查看原文) 阅读量:9 收藏
The U.S. Congressional Budget Office has confirmed it was hacked.
Caitlin Emma, a spokesperson for CBO, told TechCrunch on Friday that the agency is investigating the breach and “has identified the security incident, has taken immediate action to contain it, and has implemented additional monitoring and new security controls to further protect the agency’s systems going forward.”
CBO is a nonpartisan agency that provides economic analysis and cost estimates to lawmakers during the federal budget process, including after legislative bills get approved at the committee level in the House and Senate.
On Thursday, The Washington Post, which first revealed the breach, reported that unspecified foreign hackers were behind the intrusion. According to the Post, CBO officials are worried that the hackers accessed internal emails and chat logs, as well as communications between lawmakers’ offices and CBO researchers.
Reuters reported that the Senate Sergeant at Arms office, the Senate’s law enforcement agency, notified congressional offices of a breach, warning them that emails between CBO and the offices could have been compromised and used to craft and send phishing attacks.
It’s unclear how the hackers gained access to the CBO’s network. But soon after news of the breach became public, security researcher Kevin Beaumont wrote on Bluesky that he suspected hackers may have exploited the CBO’s outdated Cisco firewall to break into the agency’s network.
Last month, Beaumont noted that CBO had a Cisco ASA firewall on its network that was last patched in 2024. At the time of his posting, the CBO’s firewall was allegedly vulnerable to a series of newly discovered security bugs, which were being exploited by suspected Chinese government-backed hackers.

Beaumont said the CBO’s firewall had not been patched by the time the federal government shutdown took effect on October 1.
On Thursday, Beaumont said that the firewall is now offline.
The CBO’s spokesperson declined to comment when asked about Beaumont’s findings. Spokespeople for Cisco did not immediately respond to a request for comment.
