The FBI, along with cybersecurity agencies from the United States, the United Kingdom, Canada, Germany, Italy, Japan, and other allied nations, has publicly identified a Chinese government-backed hacking group known as Salt Typhoon. This cyber espionage campaign has targeted over 600 organizations across more than 80 countries, including at least 200 U.S. companies. The attacks have primarily focused on telecommunications networks but have also extended to transport, military, and government agencies. Salt Typhoon exploited vulnerabilities in products from Cisco, Ivanti, Palo Alto Networks, and Citrix NetScaler, with the latter's critical zero-day remote code execution flaw (CVE-2025-7775) remaining unpatched in over 28,000 instances worldwide. The group’s activities included infiltrating networks, stealing personal data of millions of Americans, surveilling private communications, and tracking individuals globally. An international coalition has formally called out three Chinese private technology companies for their alleged involvement in facilitating these cyberattacks. More than 20 government agencies have issued a joint cyber advisory urging companies and governments to actively hunt for and defend against Salt Typhoon threat actors. The FBI and partner agencies continue to share technical details to assist organizations in protecting their systems from this ongoing threat.
