Detects a sequence of events on Linux hosts involving a remote interactive or network logon from an external IP, followed within 5 minutes by root-level process execution, and subsequently within 2 hours by an outbound SSH connection to a private or known attacker IP. Also includes a separate branch for direct logons from known malicious IPs.
Detects a sequence of events on a Linux device where a sudo command execution is followed within 15 minutes by a Perl process executing base64 decoding commands within the same SSH session.
Detects potential Linux privilege escalation and persistence activities by monitoring for the creation of persistence scripts in post_boot.d, modifications to the sudoers.template file appending NOPASSWD, or system configuration rebuilds shortly after sudoers template changes.

Detects creation or modification of files under /etc/sudoers or /etc/sudoers.d/ by a
process outside sanctioned package- and configuration-management tooling. Writing a
passwordless sudo rule is the finishing move in CIFSwitch (CVE-2026-46243) and OVSwrap
(CVE-2026-64531) and a common root-persistence step generally. Enriched with writer
context (non-root, writable-path, shell one-liner, NOPASSWD) and a heuristic RiskScore /
TriagePriority, plus DeviceInfo host context (MachineGroup, OS, logged-on users).
Detection logic adapted from Elastic Security Labs - Linux LPE detection framework.

This rule monitors Linux system logs for attempts to modify the /etc/sudoers file, utilize sudoers.d configurations, or execute commands with NOPASSWD privileges. These activities are common precursors to privilege escalation or persistence through elevated command execution.
Detects the execution of Python 3.12 commands via 'sudo' to elevate privileges to 'root'. The rule monitors for instances where a non-root account invokes 'sudo python3.12' and subsequently spawns a process or logs activity confirming a root-level execution session within a short time window.
Detects non-interactive 'sudo -n' used to test for or invoke a passwordless sudo rule
(e.g. 'sudo -n true', 'sudo -n -l', 'sudo -n bash'). Directly follows the sudoers write in
the OVSwrap (CVE-2026-64531) chain and is a common post-exploit validation step.

This rule monitors for potential privilege escalation activity occurring shortly after an initial authentication event. It includes two primary vectors: 1) Azure AD users assigned to highly privileged roles shortly after a successful sign-in; 2) Users performing interactive or remote logons to Linux/Unix systems followed quickly by sudo or su commands to obtain root privileges.
Detects interactive root shell requests via 'sudo -i' that occur shortly after a failed Parallels appliance installation or tar extraction event containing specific error codes or configuration markers (UCP_UID=0). This pattern aligns with the exploitation chain for CVE-2026-90894, where an attacker leverages an extraction failure to escalate privileges.
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.

Attackers often modify these files to bypass authentication mechanisms and achieve privilege escalation. The rule excludes common package management tools to minimize false positives.
This rule detects potentially malicious activity involving Linux backup software (Acronis) or attempts to modify file permissions (chmod setuid) to elevate privileges. It triggers when backup-related processes are executed by root or when commands indicative of privilege escalation or tampering occur in conjunction with backup-related paths or binaries.
This rule detects potentially unauthorized root account activity by monitoring for 'root' logon events and privileged process execution (such as 'su' or 'sudo'). It flags sessions or commands that occur outside of defined business hours, originate from unapproved IP addresses, use unapproved accounts, or are executed via suspicious parent processes, providing a high-confidence indicator of anomalous administrative behavior.
