The U.S. Cybersecurity and Infrastructure Security Agency (CISA), in collaboration with the NSA, FBI, and a wide array of international partners, has published a detailed cybersecurity advisory that exposes a significant espionage campaign orchestrated by state-sponsored actors from the People’s Republic of China (PRC). The 37-page report, titled “Countering Chinese State-Sponsored Actors Compromise of Networks Worldwide to Feed Global Espionage System,” delineates the tactics, techniques, and procedures (TTPs) employed by these advanced persistent threat (APT) groups to infiltrate and sustain long-term access to critical infrastructures, including telecommunications, government, transportation, and military networks. Key recommendations from the advisory include utilising the MITRE ATT&CK/D3FEND framework to counter these threats, enforcing management isolation, disabling risky features, and mandating strong authentication practices.
The advisory highlights that these cyber actors, identified by industry groups under monikers such as “Salt Typhoon” and “GhostEmperor,” have been active since at least 2021, with the objective of pilfering data that enables Chinese intelligence services to monitor the communications and movements of their targets globally. The report explicitly associates these activities with several Chinese technology firms, notably Sichuan Juxinhe Network Technology Co. Ltd., which is alleged to provide services to China’s military and intelligence sectors. A critical finding of the investigation reveals that these actors are not relying on zero-day exploits; rather, they are achieving significant success by exploiting publicly known and frequently unpatched common vulnerabilities and exposures (CVEs). The report urges network defenders to prioritise patching specific vulnerabilities affecting Cisco, Palo Alto Networks, and Ivanti devices to mitigate these threats effectively.
