This rule monitors for suspicious process execution (e.g., cmd, powershell) spawned from PaperCut service processes (pc-app.exe, tomcat.exe) followed by a Domain Admin group membership change on the same device within a 30-minute window. This behavior is indicative of privilege escalation attempts following the exploitation of PaperCut vulnerabilities (CVE-2026-81578/CVE-2026-82078).
This rule detects a multi-stage attack pattern consistent with a Bring Your Own Vulnerable Driver (BYOVD) chain. It identifies the installation of specific known vulnerable drivers (e.g., Alinubx.sys, nvfsflt64.sys) and the registration of a corresponding service (NvFsFilter), followed by the mass termination of various security software and EDR processes within a short timeframe. This behavior is indicative of an adversary using kernel-mode privileges to disable security controls.
Detects unexpected crashes or restarts of the Windows Defender service (MsMpEng.exe) occurring in temporal proximity to activities associated with the ShieldCrash PoC or tampering within the Windows Defender object manager namespace. This rule aims to identify potential exploitation attempts targeting Windows Defender, specifically correlating security service instability with known malicious indicators.
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 anomalous process execution where a non-privileged process spawns a child process with root/SYSTEM (uid 0) privileges without passing through recognized elevation binaries (e.g., sudo, su, pkexec). This behavior is consistent with post-exploitation privilege escalation techniques, such as exploiting hijacked file descriptors or callback structures to gain root authority.
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.

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.
This rule monitors for indicators of compromise (IOCs) associated with the Rapuncel/Cruciferra 'Bring Your Own Vulnerable Driver' (BYOVD) malware-as-a-service (MaaS) campaign. It detects malicious file hashes (associated with dropped binaries or drivers), connections to known malicious command-and-control (C2) IP addresses, and network requests to domains used by the infrastructure.
This rule monitors for indicators of compromise (IOCs) associated with the Rapuncel/Cruciferra 'Bring Your Own Vulnerable Driver' (BYOVD) malware-as-a-service (MaaS) campaign. It detects malicious file hashes (associated with dropped binaries or drivers), connections to known malicious command-and-control (C2) IP addresses, and network requests to domains used by the infrastructure.
Detects the installation or service creation of 'gdrv.sys', a known vulnerable GIGABYTE driver often abused in Bring Your Own Vulnerable Driver (BYOVD) attacks to escalate privileges.
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 loading of the kernel driver 'Alinubx.sys', identified as a renamed instance of the 'CcProtect.sys' driver. This driver is known to be abused in Bring Your Own Vulnerable Driver (BYOVD) attacks to terminate security software processes from kernel mode, specifically observed in the context of Rapuncel infostealer campaigns.
This rule monitors for the loading or interaction with specific device drivers named 'truesight.sys' or 'rentdrv2.sys'. These drivers are often associated with malicious activity, including potentially vulnerable kernel drivers used in BYOVD (Bring Your Own Vulnerable Driver) attacks or rootkit-like persistence mechanisms. The rule tracks driver loading, registry updates, process activity, and device I/O control calls related to these files.
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 anomalous process execution where a non-privileged process spawns a child process with root/SYSTEM (uid 0) privileges without passing through recognized elevation binaries (e.g., sudo, su, pkexec). This behavior is consistent with post-exploitation privilege escalation techniques, such as exploiting hijacked file descriptors or callback structures to gain root authority.
Detects the execution of the Linux 'unshare' utility to create new namespaces (user or network). This command is often used as a primitive for container escapes or privilege escalation by allowing an unprivileged user to create isolated environments. The rule excludes common container management and virtualization tools to reduce noise.
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 the loading of the Alinubx.sys kernel driver or the creation of an NvFsFilter service, which are associated with a BYOVD (Bring Your Own Vulnerable Driver) attack leveraging a renamed CcProtect driver to bypass security protections such as PPL.
Detects Microsoft Defender (MsMpEng) performing scan or remediation actions against non-standard filesystem paths, specifically NT object-manager namespace paths or CLFS-driver-prefixed paths. This behavior is indicative of an exploitation attempt (e.g., CVE-2026-69414) where an attacker uses symbolic links and CLFS driver namespaces to redirect the Defender scanning engine to arbitrary files on the system, potentially allowing file reads as SYSTEM.
Detects a suspicious scenario where a non-root process associated with Acronis backup plugins (typically used on cPanel, WHM, or Plesk servers) spawns a child process that executes with root privileges. This behavior is indicative of potential privilege escalation exploiting CVE-2026-87886.
This rule monitors for indicators of compromise (IOCs) associated with the Rapuncel/Cruciferra 'Bring Your Own Vulnerable Driver' (BYOVD) malware-as-a-service (MaaS) campaign. It detects malicious file hashes (associated with dropped binaries or drivers), connections to known malicious command-and-control (C2) IP addresses, and network requests to domains used by the infrastructure.
