Detects potential local privilege escalation (LPE) to root via an unshare invocation, tracking the process lineage from an unprivileged unshare execution to the subsequent spawning of a root-privileged shell within a short time window. This pattern is characteristic of various Linux kernel vulnerability exploits such as DirtyAH6, TUNderflow, PPPoEject, and DiagSpill, where the unshare system call is abused to enter new user namespaces to bypass security restrictions.
Detects HTTP requests containing malicious JDBC strings targeting PaperCut NG/MF print management software, which are indicative of attempts to exploit authentication bypass and remote code execution vulnerabilities (CVE-2026-81578, CVE-2026-82078).
Detects the execution of Certipy, an open-source tool used for enumerating and exploiting Active Directory Certificate Services (AD CS). The rule monitors for common command-line arguments used during various stages of AD CS attack lifecycle, including finding misconfigurations, requesting certificates, relaying, and template exploitation.
Detects indicators of the 'ShieldCrash' proof-of-concept (CVE-2026-69414 exploit bypass) on Windows systems. The rule monitors for specific malicious file activity, module loading, and the presence of decoy archive files associated with the PoC, which are used to achieve arbitrary file read as SYSTEM.
Detects the loading of the Alinubx.sys (aka CcProtect.sys) kernel driver, often dropped as nvfsflt64.sys or registered as NvFsFilter, followed by a rapid, simultaneous termination of security product processes. This activity is indicative of a BYOVD (Bring Your Own Vulnerable Driver) attack chain where kernel-mode primitives are used to terminate EDR/AV processes.
Detects the presence of the known vulnerable GIGABYTE driver (gdrv.sys) used in Bring Your Own Vulnerable Driver (BYOVD) attacks to bypass security controls and facilitate kernel-mode execution, as associated with Settra ransomware campaigns.
Detects the loading of the 'gdrv.sys' driver, which is a known vulnerable driver often used in 'Bring Your Own Vulnerable Driver' (BYOVD) attacks to facilitate privilege escalation to kernel mode.
Detects the loading of the 'gdrv.sys' driver, which is a known vulnerable driver often used in 'Bring Your Own Vulnerable Driver' (BYOVD) attacks to facilitate privilege escalation to kernel mode.
This rule detects the presence, installation, or execution attempts of the known vulnerable GIGABYTE driver (gdrv.sys). Monitoring for this specific driver is a common practice to identify attempts to perform 'Bring Your Own Vulnerable Driver' (BYOVD) attacks, which can be used for kernel-mode code execution and privilege escalation.
Detects the loading or execution of pkexec.so, which is indicative of exploitation attempts targeting CVE-2021-4034 (PwnKit). This vulnerability allows for local privilege escalation on Linux systems, including within compromised containers.
Detects the loading or execution of pkexec.so, which is indicative of exploitation attempts targeting CVE-2021-4034 (PwnKit). This vulnerability allows for local privilege escalation on Linux systems, including within compromised containers.
Detects EDRKiller.exe or WarsawKiller.exe binaries and the associated wsftprm.sys BYOVD driver used by The Gentlemen threat actor to terminate security product processes

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 unauthorized or non-privileged processes attempting to communicate with the Parallels Desktop IPC Unix socket (prl_disp_service.socket). This behavior is indicative of exploitation attempts targeting the ParaShells vulnerability (CVE-2026-90894), where an unprivileged user can leverage the socket's lack of proper signature or identity verification to escalate privileges.
Detects KATARU IoT malware embedded exploit code for CVE-2026-31431 (Copy Fail) Linux privilege escalation, identified by shared exploit-chain strings and syscall sequences used to spawn su as root
Detects anomalous MS_T120 channel binding and MCS handshake patterns characteristic of the BlueKeep (CVE-2019-0708) remote code execution vulnerability in Microsoft RDP services.
Detects the use of vulnerable kernel drivers, specifically TrueSight.sys and rentdrv2.sys, as part of a Bring Your Own Vulnerable Driver (BYOVD) technique. This activity, associated with DragonForce ransomware, involves registering or accessing these drivers and sending specific IOCTL codes (0x22E044 or 0x22E010) to terminate security software processes.
Detects indicators of the 'ShieldCrash' proof-of-concept (CVE-2026-69414 exploit bypass) on Windows systems. The rule monitors for specific malicious file activity, module loading, and the presence of decoy archive files associated with the PoC, which are used to achieve arbitrary file read as SYSTEM.
Detects behavioral indicators consistent with local privilege escalation targeting Windows ALPC subsystem vulnerabilities (CVE-2026-85880). The rule correlates: 1) Unsigned or low-prevalence processes loading sensitive ALPC-related DLLs (rpcss.dll, ntdll.dll), 2) Subsequent crashes or restarts of critical ALPC-handling system components (lsass.exe, RPCSS, wuauserv), and 3) The generation of a new SYSTEM-level process by a parent that was not previously running as SYSTEM within a short temporal window.
Detects the execution of Certipy, an open-source tool used for enumerating and exploiting Active Directory Certificate Services (AD CS). The rule monitors for common command-line arguments used during various stages of AD CS attack lifecycle, including finding misconfigurations, requesting certificates, relaying, and template exploitation.
