Detects the attempt to create an ActiveScriptEventConsumer via WMIC.EXE.
An ActiveScriptEventConsumer is a built-in Windows Management Instrumentation (WMI) class that
automatically executes a predefined script (in VBScript or JScript) whenever a specific system event occurs.
Adversaries often abuse ActiveScriptEventConsumer to maintain persistence on a compromised host by executing a malicious script whenever a specific event occurs.

Detects the usage of wmic.exe to enumerate or read Windows registry via the WMI StdRegProv class read methods (EnumKey, EnumValues, GetStringValue, etc.).
While registry reads are common, attackers may use this technique to perform reconnaissance and discover sensitive configuration values, credentials, or installed software.
The use of WMI as an alternative to standard tools like reg.exe can indicate an attempt to evade detection focused on traditional registry query commands.

Detects Windows command lines that miss a space before or after the /c flag when running a command using the cmd.exe.
This could be a sign of obfuscation of a fat finger problem (typo by the developer).

Detects the execution of a renamed binary often used by attackers or malware leveraging new Sysmon OriginalFileName datapoint.
Detects access to clipboard content via osascript, which may be used for data collection but also occurs in legitimate clipboard utilities and automation scripts
Detects the use of curl with NTLM authentication and empty credentials (-u :), which can be abused to leak the currently logged-in user's NTLMv2 challenge-response to an
attacker-controlled server, enabling offline cracking or relay attacks.
When no credentials are provided, the Microsoft-shipped curl passes a NULL identity to Windows SSPI, which automatically falls back to the current user's logon session credentials
stored in LSASS — without requiring a plaintext password.
This behavior is exclusive to the curl binary shipped by Microsoft (available since Windows 10 / Windows Server 2019), which is built with SSPI support.

UFW Disable Attempt
Sigma
Detects attempts to disable the Uncomplicated Firewall (UFW) on Linux systems.
UFW is a popular firewall management tool that provides an easy-to-use interface for configuring firewall rules.
Disabling UFW can leave a system vulnerable to attacks, as it may allow unauthorized access to network services and resources.

Detects usage of the "dir" command part of Windows CMD with the "/S" command line flag in order to enumerate files in a specified directory and all subdirectories.
An adversary may compress or encrypt data that is collected prior to exfiltration using 3rd party utilities
Detects execution of AppleScript of the macOS scripting language AppleScript.
