# F5 的股價在黑客攻擊被歸因於中國後暴跌

> F5 的股價因一起與中國黑客有關的網絡攻擊而下跌 11%，該攻擊針對其 BIG-IP 產品的開發環境。敏感文件被竊取，儘管 F5 聲稱沒有新的漏洞被利用。美國網絡安全和基礎設施安全局（CISA）發佈了緊急指令，要求聯邦機構更新安全措施，強調了對這些漏洞採取緊急行動的必要性。這一事件突顯了美國與中國之間持續的技術緊張關係，以及國家支持的網絡威脅對關鍵基礎設施構成的風險

Shares in the US cybersecurity group F5 fell 11% on Thursday after the revelation of a sophisticated cyberattack, which Bloomberg says was carried out by hackers linked to the Chinese state. The company confirmed that the attack targeted the development environment of its flagship product, BIG-IP, which is used in many critical systems. Files containing source code and information on undisclosed vulnerabilities were reportedly exfiltrated. F5, which says it discovered the intrusion in August, claims it has not identified any new malicious activity or critical vulnerabilities being exploited.

However, according Bloomberg and Mandiant, the hackers maintained a presence on the network for over a year using malware called Brickstorm, attributed to the UNC5221 group. This software is designed to ensure prolonged and discreet persistence in systems, with an estimated average infection duration of 393 days. Given the seriousness of the situation, the US agency CISA issued an emergency directive requiring all federal agencies using F5 products to immediately apply the latest security updates.

Madhu Gottumukkala, acting director of CISA, called for a rapid response, saying that "the alarming ease of exploiting these vulnerabilities requires immediate and decisive action." The UK's National Cyber Security Centre issued a similar alert. This incident, the most serious for F5 since 2022, comes amid heightened technological tensions between Washington and Beijing and highlights the vulnerability of critical infrastructure to cyberattacks by state entities.
