Detects instances of 'Synaptics.exe' initiating network connections to known suspicious domains or public IP addresses. Legitimate Synaptics driver files should not typically communicate with external C2-related infrastructure or arbitrary public internet sites, suggesting the process might be masqueraded or compromised.

This rule detects potentially malicious activity involving the modification of Excel macro security settings (specifically VBAWarnings or AccessVBOM) or the creation of autorun.inf files on removable drives. It identifies these behaviors when they coincide with the execution of Synaptics.exe within a 30-minute window, suggesting a potential correlation between local administrative tasks and malicious document-based payloads or portable drive staging.

Detects the use of the Windows Management Instrumentation Command-line (WMIC) utility to execute processes, particularly when a remote node target is specified or when using common WMI process creation arguments. This pattern is commonly used by adversaries for lateral movement and remote code execution while attempting to blend into administrative activity. Legitimate management tools have been excluded from the scope to reduce noise.

Detects the use of PowerShell cmdlets such as Invoke-WmiMethod, Invoke-CimMethod, Get-CimInstance, or Get-WmiObject to interact with the Win32_Process class for process creation on local or remote systems. This behavior is frequently associated with administrative activity but is also commonly used by adversaries for remote command execution and lateral movement.

Detects instances where the Windows Management Instrumentation service (wmiprvse.exe) launches suspicious command-line interfaces or interpreters (PowerShell, CMD, cscript, etc.), or executes scripts from sensitive/temporary directories. The rule includes exclusions for common management tools to reduce noise.

Detects remote administration activity via Windows Management Instrumentation (WMI) originating from a host that has no recorded history of performing such actions within the previous 30 days. This includes the use of wmic.exe for remote nodes, Invoke-WmiMethod, or WmiPrvSe.exe spawning common command-line interpreters or utilities.

Detects execution of rundll32.exe with command-line arguments involving 'DavWWWRoot' and external domains ('pf.ch' or 'verification.google'), which is characteristic of attempts to force remote WebDAV authentication or execute malicious code via network-hosted resources.

This rule detects potential lateral movement activity by identifying executable or script files being written to administrative shares (C$ or ADMIN$) followed by the execution of a file with the same name on the destination device within 15 minutes. It includes logic to filter out known deployment/patch management service accounts and file names to reduce noise.

Detects high-frequency, automated web scraping behavior targeting product catalog pages, indicative of content harvesting for site replication. The rule monitors IIS logs for non-browser user agents (e.g., Python, curl, Scrapy) performing rapid, multi-page requests within a short duration.

This rule detects potential execution of malicious files from removable media (e.g., USB drives). It monitors for a sequence of events where a removable drive is mounted, a file is subsequently created on that drive, and then that same file is executed within a short time window.
