Detects execution of known Proof-of-Concept binaries (pedit_cow_demo or packet_edit_meme) followed by /bin/su spawning /bin/sh, which indicates successful exploitation of the pedit COW vulnerability resulting in shellcode execution with root privileges.
Detects svchost.exe (hosting InstallService) loading InstallServicePlugin.dll from a UNC path, which is indicative of the UnCanny Local Privilege Escalation (LPE) technique. This behavior is suspicious as legitimate svchost processes typically load DLLs from local system paths, not network shares.
Detects a multi-stage execution pattern involving cmd.exe spawning PowerShell to download files from storjshare.io using System.Net.WebClient, followed by a secondary PowerShell execution using 'Start-Process -Verb RunAs' to trigger a UAC bypass, characteristic of the REF8372 campaign and OXLOADER distribution.
Detects instances where known Windows binaries vulnerable to UAC bypass (eventvwr.exe, fodhelper.exe, or sdclt.exe) spawn a child powershell.exe process with the '-ExecutionPolicy Bypass' argument. This activity is indicative of an attacker attempting to elevate privileges without triggering a UAC prompt.
Detects the creation of suspicious named pipes by low-privilege processes, which is a technique used by local privilege escalation tools (like PrintSpoofer, RoguePotato, and GodPotato) to intercept and impersonate high-privilege (SYSTEM) tokens.
Detects potential Bring Your Own Vulnerable Driver (BYOVD) attacks by monitoring for known vulnerable driver files being created or loaded as kernel modules, as well as the registration of kernel-mode drivers from non-standard or user-writable locations like Temp, Tmp, AppData, or Public directories.
Detects the execution of known privilege escalation tools such as SweetPotato, JuicyPotato, RoguePotato, PrintSpoofer, and BadPotato. These tools are commonly used by attackers to escalate privileges on compromised Windows systems.
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 Havoc Demon payload executing post-exploitation token manipulation APIs (DuplicateTokenEx) to escalate privileges to SYSTEM, specifically when the initiating process originates from the Downloads folder.
Detects anomalous user-mode processes requesting the SeLoadDriverPrivilege token privilege, which is essential for loading the EnCase driver (EEDbg.sys) into the kernel. This activity is indicative of a Bring Your Own Vulnerable Driver (BYOVD) attack using the EnCase driver.
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.
Detects potential privilege escalation attempts by the Remcos RAT loader using token impersonation. The rule looks for process command lines containing keywords related to token manipulation ('impersonate', 'token', 'duplicate', 'SeImpersonate', 'logon') specifically when the initiating process is identified as 'Remcos'.
Detects potential privilege escalation attempts by the Remcos RAT loader using token impersonation. The rule looks for process command lines containing keywords related to token manipulation ('impersonate', 'token', 'duplicate', 'SeImpersonate', 'logon') specifically when the initiating process is identified as 'Remcos'.
This rule detects the execution of 'eventviewer.exe' by scripting engines such as 'wscript.exe', 'cscript.exe', or 'vbscript.exe'. This behavior is indicative of a User Account Control (UAC) bypass technique where 'eventviewer.exe' is abused to elevate privileges without user interaction.
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.
Maps the behavioral transition where the Bomgar process spawns a child process that immediately executes commands requesting or manipulating SYSTEM or root level privileges.
Detects SYSTEM privilege escalation attempts via ctfmon.exe or cloudfiles.exe processes.
Detects attempts to escalate privileges via sudo
Detects Windows token manipulation for privilege escalation
This rule looks for adding a passwordless sudo rule for a CI runner account on Linux. Attackers who gain runner access can then become root freely. Remove the rule and audit runner images. Ask the person who used the computer whether they installed new software or clicked a link, and involve your security team if the answer is unclear.
Detects the command line sequence used by Miasma to restore passwordless sudo for the 'runner' user in GitHub Actions by overwriting sudoers via a Docker container. This specific sequence involves echoing 'runner ALL=(ALL) NOPASSWD:ALL' into a file within the /mnt/runner directory and then changing its permissions to 0440, indicative of a privileged modification to the sudoers file within a containerized GitHub Actions runner environment.
