Detects a set of suspicious network related commands often used in recon stages
Detects various indicators of Microsoft Connection Manager Profile Installer execution
ServiceDll Hijack

Detects changes to the "ServiceDLL" value related to a service in the registry.
This is often used as a method of persistence.

Detects AppLocker policy enumeration attempts via PowerShell using the Get-AppLockerPolicy cmdlet and an policy scope of either Effective, LDAP, or Local.
Detects modification of autostart extensibility point (ASEP) in registry. Adversaries may modify these keys to execute malicious code when Office files are opened.
There are various legitimate add-ins that also use these keys and this filter list might not be exhaustive.
Thus, it is recommended to review and tune filters for your environment to reduce false positives before deploying to production.

Detects suspicious sub processes of web server processes
Detects PowerShell command line arguments containing ADSI (Active Directory Service Interfaces) patterns
trying to create a new user account via the WinNT or LDAP provider. This is an uncommon method to create
user accounts and may indicate an attempt to evade detection by avoiding more commonly monitored commands
such as "net user", "New-LocalUser" or "New-ADUser".

Detects the loading of unsigned .node files.
Adversaries may abuse a lack of .node integrity checking to execute arbitrary code inside of trusted applications such as Slack.
.node files are native add-ons for Electron-based applications, which are commonly used for desktop applications like Slack, Discord, and Visual Studio Code.
This technique has been observed in the DripLoader malware, which uses unsigned .node files to load malicious native code into Electron applications.
