Detects host-level configuration changes indicative of preparing a system for the CVE-2026-46331 pedit COW exploit. This includes enabling unprivileged user namespaces via sysctl and disabling security mitigations or removing the act_pedit kernel module.
Detects potential container breakout or privilege escalation attempts originating from Gitea act-runner processes. The rule monitors for the execution of containers with dangerous security configurations (e.g., host PID/IPC namespace, privileged capabilities, disabled security modules) or the use of nsenter to break out of a container into the host environment.
Detects AnyDesk spawning suspicious child processes (cmd, powershell, etc.) indicative of local privilege escalation via the AnyDesk printer COM object impersonation vulnerability. This technique involves an attacker-controlled process communicating with the AnyDesk service's named pipe (adprinterpipe) to trigger code execution in the context of the LocalSystem AnyDesk service.
Detects CldFlt.sys driver load activity coinciding with SyncRootManager registry modifications by non-standard processes, indicating potential RedSun exploitation of CVE-2026-41091 via the Cloud Files filter driver path. This correlation suggests an attempt to establish persistence or escalate privileges by manipulating system components related to cloud file synchronization.
Detects the usage of the 'SeLoadDriverPrivilege' privilege. This privilege is required to load or unload a device driver.
With this privilege, the user can dynamically load and unload device drivers or other code in to kernel mode.
This user right does not apply to Plug and Play device drivers.
If you exclude privileged users/admins and processes, which are allowed to do so, you are maybe left with bad programs trying to load malicious kernel drivers.
This will detect Ghost-In-The-Logs (https://github.com/bats3c/Ghost-In-The-Logs) and the usage of Sysinternals and various other tools. So you have to work with a whitelist to find the bad stuff.

Detects a sequence of events characteristic of a privilege escalation exploit (referenced as CVE-2026-46331). The chain involves an unprivileged user creating a user namespace, followed by the configuration of traffic-control (tc) filters, and finally accessing sensitive setuid binaries or memory files (/proc/self/mem), indicating an attempt to escalate privileges to root.
Detects a potential privilege escalation attempt targeting the DirtyClone (CVE-2026-43503) vulnerability, where an unprivileged process executes /usr/bin/su with specific command line arguments to spawn a shell without proper authentication, effectively gaining root access.
Detects the exploitation chain of the DirtyClone (CVE-2026-43503) vulnerability on Linux systems. The rule monitors for a sequence involving an unprivileged user (UID > 1000) creating a new user/network namespace, configuring an IPsec XFRM state with loopback source/destination addresses, modifying sensitive memory via /proc/self/mem or /proc/<pid>/mem to bypass Copy-on-Write (CoW) protections, and ultimately spawning a process with root privileges.
This rule detects two scenarios on Linux systems: 1. A non-root process interacting with a root process (e.g., cross-process communication where the source is non-root and the target is root). 2. Any process (excluding root) exhibiting indicators related to 'AF_ALG' or 'splice', or mentioning 'CVE-2026-31431' in its name or description. These indicators are often associated with privilege escalation attempts or kernel exploits.
Detects evidence of VILE ransomware behavior involving token and privilege manipulation, including the use of Windows API functions such as AdjustTokenPrivileges, OpenProcessToken, and DuplicateTokenEx, as well as potential EDR bypass indicators via NT syscalls like NtCreateWaitCompletionPacket.
This rule detects potential privilege escalation or backdoor creation by monitoring for two primary indicators: 1) The modification of Windows Image File Execution Options (IFEO) registry keys for accessibility binaries (sethc.exe, osk.exe, utilman.exe, magnify.exe, narrator.exe, atbroker.exe) to point to unauthorized debuggers, and 2) The execution of common command interpreters or suspicious binaries spawned directly by these accessibility processes, which are commonly used in lock-screen bypass attacks.
This rule detects the exploitation of CVE-2026-20245 on Cisco SD-WAN Manager (vManage). It monitors for two distinct phases: 1) The suspicious upload of a tenant-list CSV file via CLI using a malicious filename, and 2) A subsequent privilege escalation attempt where the 'admin' user executes 'su' to switch to a 'troot' user, which is indicative of a backdoor account creation following successful exploitation.
This rule detects potential local privilege escalation attempts targeting the AnyDesk service. An attacker can exploit the insecure permissions of the 'adprinterpipe' named pipe created by the AnyDesk service to impersonate a client and execute arbitrary commands with NT AUTHORITY\SYSTEM privileges. The rule monitors for suspicious process creation, COM registration changes, anomalous pipe connections, and suspicious DLL loads stemming from AnyDesk processes.
This rule detects the use of specific Linux utilities often associated with local privilege escalation or container escape techniques. It monitors for commands involving 'unshare' with flags that allow user or network namespace manipulation, network traffic control ('tc') commands specifically interacting with 'pedit' or 'qdisc' which can be abused for kernel-level manipulation, 'ip netns' commands to manage network namespaces, and execution of known exploit-related filenames like 'pedit_cow_demo' or 'packet_edit_meme'.
Detects non-root users utilizing the 'tc' or 'ip' utilities to interact with kernel traffic control structures (qdisc/filter/action) specifically involving 'pedit' actions. This activity is a documented prerequisite for exploiting CVE-2026-46331, a vulnerability enabling page cache poisoning and local privilege escalation.
Detects the KuinaExtractor UAC bypass technique, which exploits the auto-elevated 'SilentCleanup' scheduled task. The rule identifies suspicious activity via two patterns: the execution of 'cleanmgr.exe' from an unexpected parent process (bypassing normal task scheduler invocation) or the explicit execution of 'schtasks.exe' to trigger the 'SilentCleanup' task.
Detects the creation of user namespaces combined with network namespace flags using 'unshare' or 'ip netns' by non-root users. This activity is a necessary precursor for exploiting the CVE-2026-46331 vulnerability (pedit COW) to gain CAP_NET_ADMIN capabilities and subsequently corrupt the Linux page cache.
Detects suspicious execution of kernel-related networking commands ('unshare', 'ip', 'modprobe', 'insmod') by non-root users that are associated with the setup or exploitation phases of the 'DirtyClone' Linux kernel privilege escalation exploit. The rule specifically looks for IPsec tunnel/policy manipulation or the loading of ESP/RxRPC kernel modules by unprivileged accounts.
Detects instances where the Windows binary fodhelper.exe spawns various shell or utility processes. This behavior is a common indicator of a User Account Control (UAC) bypass attack, where the attacker leverages the auto-elevation property of fodhelper.exe to execute arbitrary commands with higher privileges.
Detects anomalous process execution patterns indicative of privilege escalation or persistence on Linux systems. Specifically monitors for unexpected root shell access from non-privileged service accounts (e.g., www-data, apache), abuse of sudo for modifying privileged system files via tee, and execution of binaries from world-writable directories such as /tmp or /dev/shm, which is a common behavior during exploit staging.
Detects instances where the Microsoft Defender service (MsMpEng.exe) spawns common system utilities like cmd.exe, powershell.exe, or wscript.exe running with SYSTEM integrity. This is highly anomalous as Defender should generally not be the parent process for these interactive or script execution shells.
