Detects modifications to the /etc/sudoers or /etc/sudoers.d configuration files by non-root users. This activity is often associated with privilege escalation attempts where an adversary attempts to modify sudo policies to grant themselves elevated permissions or bypass password requirements.
Detects unauthorized modifications, creations, or renames of Pluggable Authentication Module (PAM) configuration files or core shared libraries (such as pam_rootok.so or pam_permit.so) by non-root users. Attackers often modify these files to bypass authentication mechanisms and achieve privilege escalation. The rule excludes common package management tools to minimize false positives.

Detects a sequence of events where a process within a container namespace attempts to interact with the host filesystem (e.g., /proc/1/root, nsenter) followed shortly by an unexpected gain of root privileges or execution of setuid(0) that is not associated with legitimate su or sudo usage.

This rule detects kernel-level stability issues or crashes (ah6/ipsec related) occurring immediately after the execution of processes that create new user namespaces (unshare, clone with CLONE_NEWUSER). This pattern is often associated with exploitation of kernel vulnerabilities, where namespace manipulation is a prerequisite for triggering a crash or privilege escalation.

This rule detects a high volume of SCTP traffic targeted at internal systems, characterized by mass endpoint creation. This behavior is indicative of an exploit attempt against the 'sctp_diag' kernel component (CVE-2026-74469), which can lead to an out-of-bounds (OOB) write condition, potentially resulting in system instability or denial of service.
