Recommended Practices
CISA recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities. CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
Recommended Practices
CISA also provides a section for control systems security recommended practices on the ICS webpage on cisa.gov/ics. Several CISA products detailing cyber defense best practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.
Recommended Practices
CISA encourages organizations to implement recommended cybersecurity strategies for proactive defense of ICS assets.
Recommended Practices
Additional mitigation guidance and recommended practices are publicly available on the ICS webpage at cisa.gov/ics in the technical information paper, ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation Strategies.
Recommended Practices
Organizations observing suspected malicious activity should follow established internal procedures and report findings to CISA for tracking and correlation against other incidents.
Recommended Practices
No known public exploitation specifically targeting these vulnerabilities has been reported to CISA at this time. These vulnerabilities are exploitable remotely. These vulnerabilities have low attack complexity.

"notes": [
{
"category": "summary",
"text": "A vulnerability named \"non-responsive delegation attack\" (NRDelegation attack) has been discovered in various DNS resolving software. The NRDelegation attack works by having a malicious delegation with a considerable number of non-responsive nameservers. The attack starts by querying a resolver for a record that relies on those unresponsive nameservers. The attack could cause a resolver to spend time/resources resolving records under a malicious delegation point where a considerable number of unresponsive NS records reside. It could trigger high CPU usage in some resolver implementations that continually look in the cache for resolved NS records in that delegation, which could lead to degraded performance and eventually denial of service in orchestrated attacks. Unbound does not suffer from high CPU usage, but still requires resources to resolve the malicious delegation. Unbound will continue to try to resolve the record until it reaches hard limits. Based on the nature of the attack and the replies, Unbound could reach different limits. From version 1.16.3 on, Unbound introduces fixes for better performance when under load by cutting opportunistic queries for nameserver discovery and DNSKEY prefetching and limiting the number of times a delegation point can issue a cache lookup for missing records.",
