The cyber actors use the VPS as well as small office and home office (SOHO) devices as operational nodes to evade detection.Ĭhinese state-sponsored cyber actors use a full array of tactics and techniques to exploit computer networks of interest worldwide and to acquire sensitive intellectual property, economic, political, and military information. Chinese state-sponsored cyber actors have been routinely observed using a VPS as an encrypted proxy. NSA CSA U/OO/179811-20: Chinese State-Sponsored Actors Exploit Publicly Known Vulnerabilities.Įncrypted Multi-Hop Proxies. For information on Common Vulnerabilities and Exposures (CVE) known to be exploited by malicious Chinese state-sponsored cyber actors, see:ĬISA-FBI Joint CSA AA20-133A: Top 10 Routinely Exploited Vulnerabilities,ĬISA Activity Alert: AA20-275A: Potential for China Cyber Response to Heightened U.S.-China Tensions, and In many cases, these cyber actors seek to exploit vulnerabilities in major applications, such as Pulse Secure, Apache, F5 Big-IP, and Microsoft products.
Chinese state-sponsored cyber actors consistently scan target networks for critical and high vulnerabilities within days of the vulnerability’s public disclosure.

These actors take effort to mask their activities by using a revolving series of virtual private servers (VPSs) and common open-source or commercial penetration tools.Įxploitation of Public Vulnerabilities. Chinese state-sponsored cyber actors remain agile and cognizant of the information security community’s practices. NSA, CISA, and FBI have identified the following trends in Chinese state-sponsored malicious cyber operations through proactive and retrospective analysis:Īcquisition of Infrastructure and Capabilities. political, economic, military, educational, and CI personnel and organizations.

Note: NSA, CISA, and FBI encourage organization leaders to review CISA Joint Insights: Chinese Malicious Cyber Activity: Threat Overview for Leaders for information on this threat to their organization.Ĭlick here for a PDF version of this report. To increase the defensive posture of their critical networks and reduce the risk of Chinese malicious cyber activity, NSA, CISA, and FBI urge government, CI, DIB, and private industry organizations to apply the recommendations listed in the Mitigations section of this advisory and in Appendix A: Chinese State-sponsored Cyber Actors' Observed Procedures. This advisory builds on previous NSA, CISA, and FBI reporting to inform federal, state, local, tribal, and territorial (SLTT) government, CI, DIB, and private industry organizations about notable trends and persistent TTPs through collaborative, proactive, and retrospective analysis. This Joint Cybersecurity Advisory (CSA) provides information on tactics, techniques, and procedures (TTPs) used by Chinese state-sponsored cyber actors. These cyber operations support China’s long-term economic and military development objectives. Some target sectors include managed service providers, semiconductor companies, the Defense Industrial Base (DIB), universities, and medical institutions. and allied political, economic, military, educational, and critical infrastructure (CI) personnel and organizations to steal sensitive data, critical and emerging key technologies, intellectual property, and personally identifiable information (PII). Chinese state-sponsored cyber actors aggressively target U.S. The National Security Agency, Cybersecurity and Infrastructure Security Agency (CISA), and Federal Bureau of Investigation (FBI) assess that People’s Republic of China state-sponsored malicious cyber activity is a major threat to U.S. See the ATT&CK for Enterprise for all referenced threat actor tactics and techniques and the D3FEND framework for referenced defensive tactics and techniques. This advisory uses the MITRE Adversarial Tactics, Techniques, and Common Knowledge (ATT&CK®) framework, Version 9, and MITRE D3FEND™ framework, version 0.9.2-BETA-3.
