Detecting Exploitation of CVE-2021-44228 (Log4j2) with Elastic Security
Elastic Security released detection rules and hunting queries to identify active exploitation of CVE-2021-44228 (Log4Shell), a critical remote code execution vulnerability in the Log4j2 logging framework affecting versions 2.0-beta9 through 2.14.1. The detections focus on identifying suspicious sequences of Java processes making outbound connections to LDAP, RMI, or DNS ports followed by shell command execution, as well as indicators of post-exploitation activity such as cryptocurrency mining and file downloads.
Why it matters: Organizations running Java applications with vulnerable Log4j2 versions need to deploy these detection rules immediately to identify active compromise in their environment before attackers establish persistence or exfiltrate data.
