2022: A Look Back On A Year Of Mass Exploitation
Summary: GreyNoise Intelligence added over 230 tags since January 1, 2022, covering detections for more than 160 CVEs, and its retrospective highlights four vulnerabilities including Log4j, Atlassian Confluence OGNL injection, Apache httpd path traversal and remote code execution, and the F5 BIG-IP iControl REST authentication bypass. During Log4j's initial exploitation period, every one of GreyNoise's more than 600 sensors fielded exploit traffic, handling nearly one million attempts in the first week, while Confluence exploitation peaked at nearly 1,000 unique IP addresses and Apache httpd traversal attempts rose to nearly three times their initial volume.
What you should know: GreyNoise reports its tag creation beat CISA's KEV catalog CVE updates 60% of the time and tied them 5% of the time across more than 100 KEV CVEs, meaning defenders relying solely on the federal list may be working from a lagging signal. Confluence remains a standing target, with a daily average of nearly 20 unique addresses still probing for unpatched instances.
