The findings are based on the Tenable Research team’s analysis of cybersecurity events, vulnerabilities and trends throughout 2022, including an analysis of 1,335 data breach incidents publicly disclosed between November 2021 and October 2022. The Tenable Threat Landscape Report categorizes important vulnerability data and analyzes attacker behavior to help organizations inform their security programs and prioritize security efforts to focus on areas of greatest risk and disrupt attack paths, ultimately reducing exposure to cyber incidents. Of the events analyzed, more than 2.29 billion records were exposed, which accounted for 257 Terabytes of data.

Threat actors continue to find success with known and proven exploitable vulnerabilities that organizations have failed to patch or remediate successfully. According to the Tenable report, the number one group of most-frequently exploited vulnerabilities represents a large pool of known vulnerabilities, some of which were originally disclosed as far back as 2017. Organizations that failed to apply vendor patches for these vulnerabilities were at increased risk of attacks throughout 2022. The top exploited vulnerabilities within this group include several high-severity flaws in Microsoft Exchange, Zoho ManageEngine products and virtual private network solutions from Fortinet, Citrix and Pulse Secure. For the other four most commonly exploited vulnerabilities – including Log4Shell; Follina; an Atlassian Confluence Server and Data Center flaw; and ProxyShell – patches and mitigations were highly publicized and readily available. In fact, four of the first five zero-day vulnerabilities exploited in the wild in 2022 were disclosed to the public on the same day the vendor released patches and actionable mitigation guidance. “The data hi...
