NSA Alert: Chinese State-Sponsored Actors Exploit Known Vulnerabilities
On October 20, 2020, the United States National Security Agency (NSA) released a cybersecurity advisory on Chinese state-sponsored malicious cyber activity. The NSA alert provided a list of 25 publicly known vulnerabilities that are known to be recently leveraged by cyber actors for various hacking operations.
“Since these techniques include exploitation of publicly known vulnerabilities, it is critical that network defenders prioritize patching and
mitigation efforts,” said the NSA advisory. It also recommended “critical system owners consider these actions a priority, in order to mitigate the loss of sensitive information that could impact U.S. policies, strategies, plans, and competitive advantage.”
Earlier this year, the NSA also announced Sandworm actors exploiting the Exim MTA Vulnerability. Similar alerts have been published by the Cybersecurity and Infrastructure Security Agency (CISA) over the last year. CISA also issued an advisory notifying about vulnerabilities that were exploited in the wild to retrieve sensitive data such as intellectual property, economic, political, and military information.
Here is a list of 25 publicly known vulnerabilities (CVEs) published by the NSA, along affected products and associated Qualys VMDR QID(s) for each vulnerability:

Detect 25 Publicly Known Vulnerabilities using VMDR
Qualys released several remote and authenticated QIDs for commonly exploited vulnerabilities. You can search for these QIDs in VMDR Dashboard by using the following QQL query:
Using Qualys VMDR, customers can effectively prioritize this vulnerability for “Active Attack” RTI:
Identify Vulnerable Assets using Qualys Threat Protection
In addition, Qualys customers can locate vulnerable host through Qualys Threat Protection by simply clicking on the impacted hosts. This helps in effectively identifying and tracking this vulnerability.
With VMDR Dashboard, you can track 25 publicly known exploited vulnerabilities, their impacted hosts, their status and overall management in real time. With trending enabled for dashboard widgets, you can keep track of these vulnerabilities trends in your environment using the “NSA’s Top 25 Vulnerabilities from China” dashboard.
As guided by CISA, to protect assets from exploiting, one must do the following:
- Minimize gaps in personnel availability and consistently consume relevant threat intelligence.
- Vigilance team of an organization should keep a close eye on indications of compromise (IOCs) as well as strict reporting processes.
- Regular incident response exercises at the organizational level are always recommended as a proactive approach.
Remediation and Mitigation
- Patch systems and equipment promptly and diligently.
- Implement rigorous configuration management programs.
- Disable unnecessary ports, protocols, and services.
- Enhance monitoring of network and email traffic.
- Use protection capabilities to stop malicious activity.
