The information contained on this page is the result of analytic efforts of the Cybersecurity and Infrastructure Security Agency (CISA) to provide technical details on the tactics, techniques, and procedures used by People’s Republic of China (PRC) cyber threat actors.
PRC Targeting of COVID-19 Research Organizations
On May 13, 2020, CISA and the Federal Bureau of Investigation (FBI) issued a Public Service Announcement warning organizations researching COVID-19 of likely targeting and attempted network compromise by the People’s Republic of China (PRC). Healthcare, pharmaceutical, and research sectors working on the COVID-19 response should all be aware they are the prime targets of this activity and take the necessary steps to protect their systems.
China’s efforts to target these sectors pose a significant threat to our nation’s response to COVID-19. This announcement is intended to raise awareness for research institutions and the American public and provide resources and guidance for those who may be targeted.
The FBI requests organizations who suspect suspicious activity to contact their local FBI field office. CISA is asking for all organizations supporting the COVID-19 response to partner with the agency in order to help protect these critical response efforts. CISA requests organizations to report incidents via the CISA Incident Reporting System.
Information for IT Service Providers and their Customers
Chinese government cyber threat actors are actively exploiting trust relationships between information technology (IT) service providers—such as managed service providers and cloud service providers—and their customers. The intent of sharing this information is to enable network defenders to identify and reduce exposure to Chinese malicious cyber activity. However, mitigation for this activity can be complex and there is no single solution that will fully alleviate all aspects of the threat actor activity.
At this time, all known victims of this activity have been notified by CISA and/or the Federal Bureau of Investigation (FBI). However, because there may be additional victims not yet identified, CISA recommends all IT service providers and their customers follow the recommendations, tools, and actions described in this page and in Alerts TA17-117A and TA18-276A, referenced below. Organizations and individuals that determine their risk to be elevated—either because they are in one of the targeted sectors, or because unusual activity is detected—should conduct a dedicated investigation to identify if any of this malicious activity is in their networks.

Guidance for IT Service Provider Customers
- Organizations that rely on IT service providers should ensure their providers have conducted a review to determine if there is a security concern or compromise, and have implemented appropriate mitigation and detection tools for this cyber activity.
- IT service provider customers should also
- Review and verify all connections between customer systems, service provider systems, and other client enclaves;
- Verify service provider accounts in their environment are being used for appropriate purposes and are disabled when not actively being used;
- Ensure contractual relationships with all service providers implement
- Security controls as deemed appropriate by the client,
- Appropriate monitoring and logging of client systems provided by the service provider,
- Appropriate monitoring of service provider’s presence, activities, and connections to the customer network, and
- Notification of confirmed or suspected security events and incidents occurring on the provider’s infrastructure and administrative networks.
- Integrate system log files—and network monitoring data from IT service provider infrastructure and systems—into customer intrusion detection and security monitoring systems for independent correlation, aggregation and detection.
- IT service provider customers should consult the APTs Targeting IT Service Provider Customers site page that includes the following tools and alerts:
- Tools To Detect Network Intrusions and Identify Compromised Systems
- October 3, 2018: Alert (TA18-276B) - Advanced Persistent Threat Activity Exploiting Managed Service Providers
- October 3, 2018: Alert (TA18-276A) - Using Rigorous Credential Control to Mitigate Trusted Network Exploitation
Guidance for IT Service Providers
- Providers should fully implement the mitigation actions available on the APTs Targeting IT Service Provider Customers site page to protect against this malicious activity.
- Providers should implement the following specific actions:
- Apply the principle of least privilege to their environment, which means customer data sets are separated logically, and access to client networks is not shared;
- Implement robust network and host-based monitoring solutions that looks for known malicious activity and anomalous behavior on the infrastructure and systems providing client services;
- Ensure that log information is aggregated and correlated to enable maximum detection capabilities, with a focus on monitoring for account misuse; and
- Work with their customers to ensure hosted infrastructure is monitored and maintained, either by the service provider or the client.
- Providers may consult the following private industry report:
