Detect SharpHound Command-Line Arguments

The following analytic detects the execution of SharpHound command-line arguments, specifically `-collectionMethod` and `invoke-bloodhound`. It leverages data from Endpoint Detection and Response (EDR) agents, focusing on process names and command-line executions. This activity is significant as SharpHound is commonly used for Active Directory enumeration, which can be a precursor to lateral movement or privilege escalation. If confirmed malicious, this activity could allow an attacker to map out the network, identify high-value targets, and plan further attacks, potentially compromising sensitive information and critical systems.
