Detects SQL Server executing OS commands via xp_cmdshell, a known privilege escalation vector. This rule specifically looks for 'sqlservr.exe' as the initiating process and 'xp_cmdshell' in the process command line.
Detects multiple instances of a non-SYSTEM or non-LOCAL SERVICE account using 'RunAs' to execute processes as highly privileged accounts (admin, system, root) within a short timeframe. This could indicate an attempt at privilege escalation or token impersonation.
Detects command-line activity associated with the Print Spooler service (`printspooler` or `spoolsv.exe`) that also contains keywords indicative of exploitation or privilege escalation (e.g., `exploit`, `privilege`, `admin`). This rule aims to identify attempts to leverage Print Spooler vulnerabilities for privilege escalation.
Detects loading of GameDriverx64.sys, which has been identified as a vulnerable driver (CVE-2025-61155) that can be exploited for kernel-level privilege escalation.
Detects execution of tools known to manipulate Windows access tokens
Detects execution of tools known to manipulate Windows access tokens
This rule detects the creation of new processes (EventID 4688) where the command line contains keywords commonly associated with User Account Control (UAC) bypass techniques, such as 'uac', 'UAC', or 'bypassuac'. This could indicate an attempt to elevate privileges without user consent.
Detects privilege escalation attempts utilizing PowerShell's Start-Process cmdlet with the 'RunAs' verb. This technique can be used by malware like Lucid Stealer's UAC module to elevate privileges.
This rule detects suspicious command-line activity indicative of direct kernel object manipulation, often associated with kernel-mode rootkits. It looks for processes executing commands containing keywords related to direct kernel access (e.g., 'directl', 'kernel call', 'ntoskrnl', 'hal.dll') in conjunction with keywords suggesting privilege escalation or driver loading (e.g., 'setprivileges', 'loaddriver', 'createremotethread'). Such combinations can signify attempts to install or interact with malicious kernel drivers or rootkits.
This rule detects the spawning of a root shell from specific SUID binaries (su, sudo, doas, passwd, chsh) when the initiating process was run by an unprivileged user. This behavior is indicative of a privilege escalation exploit, potentially related to CVE-2026-45257 (BUMSRAKETE).
This rule detects potential User Account Control (UAC) bypass attempts by monitoring the creation of processes for 'fodhelper.exe', 'computerdefaults.exe', or 'slui.exe' when their parent process is not 'explorer.exe' or 'svchost.exe'. These executables are known to be used in UAC bypass techniques to elevate privileges without user interaction.
Detects the creation of Kubernetes pods with dangerous security settings that could lead to privilege escalation or container escape. This includes configurations such as enabling hostNetwork, allowing privilege escalation within containers, or running containers as the root user (UID 0).
Detects privilege escalation attempts utilizing PowerShell's Start-Process cmdlet with the 'RunAs' verb. This technique can be used by malware like Lucid Stealer's UAC module to elevate privileges.
Detects use of CreateProcessWithTokenW for spawning elevated processes
This rule detects the execution of processes where the command line contains keywords commonly associated with privilege escalation or gaining administrative privileges, such as 'getadmin' or 'privesc'. It monitors Windows Security Event ID 4688, which logs process creation.
This rule detects repeated attempts to use privileges for access checks (EventID 4673) by a single user within a one-hour window, excluding the 'SeTrustedCredentialManagerAccessPrivilege'. A high count of such events (5 or more) could indicate an attempt at privilege escalation or unusual system access behavior.
This rule detects when a user account repeatedly (3 or more times within an hour) requests either 'SeDebugPrivilege' or 'SeImpersonatePrivilege' (Event ID 4672). This behavior can be indicative of an attacker attempting to escalate privileges or manipulate access tokens, often seen in techniques like token impersonation or debugging processes for malicious purposes.
This rule detects attempts to manipulate the sudo timestamp cache by looking for repeated 'sudo -n' commands within a short timeframe. The 'sudo -n' command allows sudo to run a command without prompting for a password, which can be abused by an attacker to maintain sudo privileges or bypass re-authentication if they have already compromised a user's session. The thresholding mechanism (10 times in 30 seconds from the same source IP) aims to reduce false positives from legitimate, infrequent uses of 'sudo -n' and focus on potential automated or rapid attempts to interact with sudo without password prompts, possibly to keep the timestamp alive or to quickly execute multiple commands.
This rule detects potential privilege escalation attempts on UniFi OS systems where the 'ucs-update' service account uses 'sudo' to execute sensitive commands like 'dpkg', 'chmod', or 'systemctl'. This behavior is indicative of the vulnerability described in the Bishop Fox research, where an unauthenticated RCE chain can lead to root escalation.
Detects command-line activity associated with the Print Spooler service (`printspooler` or `spoolsv.exe`) that also contains keywords indicative of exploitation or privilege escalation (e.g., `exploit`, `privilege`, `admin`). This rule aims to identify attempts to leverage Print Spooler vulnerabilities for privilege escalation.
Detects DLL side-loading attacks where consent.exe loads known malicious DLLs (version.dll, rtworkq.dll, wmsgapi.dll, and the older msimg32.dll) from non-standard locations. This technique is used by Shanya-packed malware including EDR Killer and CastleRAT to load malicious payloads while appearing as a legitimate Windows UAC process.
