Most Exploited Vulnerabilities during 2016- 2019 A concerted patching campaign would also bolster network security by focusing scarce defensive resources on the observed activities of nation state adversaries. A concerted campaign to patch these vulnerabilities would introduce friction into adversaries’ operational tradecraft and force them to develop or acquire exploits that are more costly and less widely effective. Health-ISAC member organizations could reduce the threats from some sophisticated nation state actors through an increased effort to patch systems and implement programs to keep system patching up to date. Exploitation of these vulnerabilities often requires fewer resources as compared with zero-day exploits for which no patches are available. Government issued an alert (AA20-133A) to advise IT security professionals at public and private sector organizations to place an increased priority on patching the most commonly known vulnerabilities exploited by sophisticated foreign cyber actors.įoreign cyber actors continue to exploit publicly known-and often dated-software vulnerabilities against broad target sets, including public and private sector organizations, including the healthcare sector. On May 13, 2020, the Cybersecurity and Infrastructure Security Agency (CISA), the Federal Bureau of Investigation (FBI), and the broader U.S. Organizations can greatly reduce the risk of these foreign threats by applying patches.

This alert provides details on vulnerabilities that are routinely being exploited by nation state cyber actors. Event: Top 10 Routinely Exploited Common Vulnerabilities & Exposures (CVEs)
