This rule detects the creation of files named release_agent or notify_on_release, which are
|
|
commonly associated with the abuse of Linux cgroup release mechanisms. In Docker or containerized
|
|
environments, this behavior may indicate an attempt to exploit privilege escalation vulnerabilities
|
|
such as CVE-2022-0492, where attackers use the release_agent feature to execute code on the host
|

from within a container.
