Detects the use of PowerShell to modify Microsoft Defender antivirus preferences by adding exclusion paths or processes. This behavior is indicative of an attacker attempting to bypass security software detection by excluding their malicious tools or staging areas from scanning.
Detects exploitation attempts by the CARBONATO botnet targeting exposed Docker daemons. The rule monitors for container escape techniques using 'nsenter' to access host namespaces, the execution of specific malicious entrypoint scripts, the use of known malicious container image references, and the creation of privileged containers with host bind mounts, which are indicative of host filesystem and network compromise.
Detects various persistence mechanisms used by the CARBONATO botnet on Linux systems, including registration of cron jobs, systemd services/timers, and the usage of 'chattr +i' to make persistence files immutable.
Detects a multi-stage installation of the Level RMM agent. This rule monitors for a correlation of events including the execution of 'LevelInstaller.exe' with specific installation arguments, file drops in potentially spoofed vendor paths (Dell or Level), the creation of a 'Level' service, and the addition of a 'Level Watchdog' scheduled task on the same device within a 24-hour window.
Detects non-interactive 'sudo -n' used to test for or invoke a passwordless sudo rule
(e.g. 'sudo -n true', 'sudo -n -l', 'sudo -n bash'). Directly follows the sudoers write in
the OVSwrap (CVE-2026-64531) chain and is a common post-exploit validation step.
Detection logic adapted from Elastic Security Labs - Linux LPE detection framework.

Detects instances where the Internet Information Services (IIS) worker process (w3wp.exe) initiates a child process of sqlcmd.exe. This behavior is highly suspicious and often indicates a post-exploitation activity where an attacker, having established a webshell or similar foothold on a web server, is using harvested credentials to query backend SQL databases directly.
Detects instances where an IIS worker process (w3wp.exe) spawns a command shell (cmd.exe) that executes a conditional file copy operation. This pattern is characteristic of an adversary creating a webshell by copying a payload to a filename that masquerades as a legitimate web application asset, such as a CSS bundle or validation script.
This rule monitors for suspicious command-line activity involving the Fortis payment processor's webhook log files. It detects when attackers use tools like 'findstr', 'cmd', or 'dir' to navigate directories containing webhook data and specifically searches for payment card fields such as CVV, primary account numbers, and expiration dates, which is a common indicator of post-compromise data exfiltration.
Detects anomalous execution of the Microsoft Support Diagnostic Tool (msdt.exe) or its host process (sdiagnhost.exe) when spawned by Microsoft Office applications or when invoked with specific command-line arguments indicative of the CVE-2022-30190 (Follina) exploit.
Detects known file hashes associated with SideCopy/ReverseRAT.
Detects known file hashes associated with SideCopy/ReverseRAT.
Detects unauthorized or suspicious use of USSD codes by the corporate MDM agent to modify call-forwarding settings. This activity is indicative of a compromise where an attacker uses an MDM-controlled device to intercept calls or divert communications.
Detects the execution of the sckit Go implant, linked to the MemTensor supply chain compromise, during its host-profiling stage. The rule monitors for the 'sckit' binary being executed with 'stage0' and '--config64' command-line arguments, or being spawned by legitimate runtime interpreters like Node.js or Python, indicating an attempt to profile host information (timezone, language, privileges) and subsequent self-deletion.
Detects potential staging and execution chains involving remote MSI file fetching via msiexec.exe, or the execution of .wsf scripts or registry imports originating from or residing in AppData directories. This behavior is indicative of multistage malware delivery or persistence mechanisms where components are downloaded and executed using LOLBins.
Detects suspicious execution patterns characteristic of post-exploitation activity, such as invoking 'go run' or 'node' from non-standard directories like AppData or Temp, as well as the use of command-line routines to delete files after execution (often associated with self-deleting secondary payloads or persistence cleanup).
Detects the execution of known credential harvesting tools such as Mimikatz, LaZagne, and pypykatz, or the use of their specific command-line arguments. The rule includes exclusions for common security software processes and authorized testing paths.
Detects the spawning of common administrative or script-execution tools as child processes from SharePoint-related processes (w3wp.exe or OWSTIMER.EXE). This behavior is often indicative of exploitation attempts targeting SharePoint application pools to execute arbitrary code.
Detects suspicious command execution patterns on macOS frequently associated with the 'ClickFix' technique utilized by AMOS (Atomic macOS Stealer). This includes piping base64-encoded curl downloads directly to a shell, utilizing osascript to execute shell commands, and modifications to LaunchAgents for potential persistence.
Detects potential manual paste-and-run execution patterns where a shell or interpreter is launched directly from Windows Explorer (e.g., via the Run dialog or manual clipboard paste), correlated with either command-line references to or outbound network connections towards Cloudflare Tunnel services (trycloudflare.com, workers.dev). The rule specifically identifies one-off execution events by excluding cases where explorer.exe spawns multiple child processes simultaneously, indicating non-routine shell behavior.
This rule detects a specific persistence technique used by AvisLoader malware. It monitors for the creation of a .lnk.backup file alongside a corresponding .lnk shortcut modification in common shell locations (Desktop, Taskbar, etc.), coupled with the execution of wscript.exe or cscript.exe referencing the 'VLCAssistant' VBScript within a short time window. This sequence indicates an attempt to persist malicious activity by backing up existing shortcuts and replacing them with a launcher for the AvisLoader payload.
