Detects indicators of exploitation related to CVE-2026-20245 on Cisco Catalyst SD-WAN controllers, including malicious tenant CSV uploads, unauthorized account creation (troot), privilege escalation via su, anti-forensic backup of system configuration files, and configuration changes such as PermitRootLogin enabled.
Detects the post-exploitation pattern associated with the DirtyClone (CVE-2026-43503) vulnerability, where a non-root process executes '/usr/bin/su' with the '-c /bin/sh' argument, resulting in a spawned shell running with root privileges. This behavior is indicative of an in-memory patch to the su binary's page cache, allowing for unauthorized privilege escalation without modifying the on-disk binary or triggering standard PAM authentication events.
Detects behaviors associated with 'Bring Your Own Vulnerable Driver' (BYOVD) attacks, including the dropping of .sys driver files into non-canonical directories, the registration and execution of kernel services via sc.exe, the use of fltMC to load filter drivers, and the loading of driver modules from non-standard locations.
This rule detects potentially malicious activities related to Active Directory Certificate Services (AD CS). It identifies suspicious certificate export commands (certutil, PowerShell), non-privileged processes writing to system certificate stores, and dangerous AD CS enrollment patterns such as Subject Alternative Name (SAN) modifications, often associated with ESC1 privilege escalation techniques.
Detects instances where a non-SYSTEM parent process spawns a child process running as SYSTEM, characteristic of 'Potato' family exploits (e.g., JuicyPotato, PrintSpoofer) leveraging SeImpersonatePrivilege to elevate privileges. The rule specifically filters for known legitimate SYSTEM process spawners while highlighting suspicious parent-child process relationships.
Detects the execution of known Windows privilege escalation tools commonly referred to as 'potato' exploits (e.g., JuicyPotato, SweetPotato, PrintSpoofer). These tools typically exploit service account misconfigurations or Windows APIs to achieve local privilege escalation to SYSTEM.
Detects the creation of specific vulnerable driver files abused by Gentlemen RaaS EDR killers. Gentlemen operators rapidly deploy new BYOVD proofs-of-concept to evade and disable host defenses by dropping known vulnerable drivers to disk.
Detects potential local privilege escalation (LPE) attempts targeting the AnyDesk adprinterpipe named pipe. The rule monitors for the execution of known malicious indicators, unauthorized access to the adprinterpipe, AnyDesk spawning unexpected processes as SYSTEM, and the creation of services by AnyDesk child processes.
Detects the creation or loading of the vulnerable EnCase forensic driver 'OemHwUpd.sys'. This driver is being exploited in Bring Your Own Vulnerable Driver (BYOVD) attacks to terminate security products.
Detects attempts to exploit the PwnKit vulnerability (CVE-2021-4034) in Polkit's pkexec. The rule monitors for malicious command-line arguments involving GCONV_PATH environment manipulation, the execution of pkexec by non-root users, and the presence of associated PwnKit payload artifacts, such as base64-encoded strings or specific chunked files.
Detects suspicious activity involving the combination of user or network namespace creation using 'unshare' or 'ip' and subsequent manipulation of kernel networking queues using 'tc' (Traffic Control). This behavioral pattern is frequently observed in Linux kernel exploits designed to achieve local privilege escalation by creating namespaces and using the 'tc' subsystem to trigger vulnerabilities. The rule further refines matches by flagging commands or parent processes residing in directories associated with staging or temporary storage, such as /tmp or /dev/shm.
Detects the spawning of root shells from suid binaries (su) in conjunction with user namespace creation or suspicious parent process execution, potentially indicating exploitation of local privilege escalation vulnerabilities like the pedit COW page cache poisoning (CVE-2026-46331). The detection correlates non-root process activity in suspicious locations with subsequent elevated shell creation.
Detects execution patterns associated with the DirtyClone (CVE-2026-43503) exploit, which involves an unprivileged process utilizing user and network namespaces to configure IPsec XFRM Security Associations (SAs) to corrupt the kernel page cache of sensitive binaries such as /usr/bin/su.
Detects a sequence of events consistent with the DirtyClone/DirtyFrag kernel exploit: first, identifying precursor activities such as namespace manipulation (unshare), kernel module loading of networking components (esp4/6, rxrpc), or specific exploit binary execution; followed by an anomalous spawn of a root shell from an unprivileged parent process within a short 5-minute window.
Detects the exploit chain for CVE-2026-43503, an unprivileged kernel exploitation vulnerability. The rule identifies the creation of user and network namespaces by non-root users, followed by the manipulation of XFRM states or policies, and the subsequent loading of ESP kernel modules, which together facilitate privilege escalation.
This rule detects suspicious manipulation of Linux namespaces using the 'unshare' utility or manual modification of user ID mapping files ('uid_map', 'gid_map', 'setgroups') in '/proc/self/'. Such activities are characteristic of container escape attempts or privilege escalation, where an attacker seeks to gain root access on the host or map unprivileged users to privileged IDs within a new namespace.
This rule detects the usage of standard Windows system administration utilities (infinstall.exe, devcon.exe, pnputil.exe, sc.exe) when the command line arguments include keywords commonly associated with driver loading or kernel-level operations, which may indicate the installation of a rootkit or malicious driver.
Detects indicators of exploitation attempts for the libssh2 pre-auth heap RCE vulnerability (CVE-2026-55200). The rule monitors for the execution of known harness binaries, abnormal child processes spawned by sshd, unauthorized file creation in sensitive temporary directories, and the loading of libssh2 libraries from non-standard, writable locations.
Detects a potential privilege escalation attempt in MyBB where a user with limited Administrator Control Panel (ACP) permissions modifies a user account to join the 'Administrator' group (ID 4) by POSTing to the 'user-users' module.
This rule monitors Cisco Unified Communications Manager (UCM) environments for multiple stages of an attack chain, including potential Server-Side Request Forgery (SSRF) attempts against administrative interfaces, suspicious file modifications by service accounts, indicators of privilege escalation, and anomalous outbound network connections from core Cisco processes.
Detects unauthorized attempts by a non-super-administrator user within the MyBB Admin Control Panel to assign the administrator group (usergroup=4) to a new or existing user, exploiting a privilege boundary bypass.
