  This rule detects execution of a PowerShell code through the sqltoolsps.exe utility, which is included in the standard set of utilities supplied with the Microsoft SQL Server Management studio.
  Script blocks are not logged in this case, so this utility helps to bypass protection mechanisms based on the analysis of these logs.

description: |
    Detects potential network sniffing via use of network tools such as "tshark", "windump".
    Network sniffing refers to using the network interface on a system to monitor or capture information sent over a wired or wireless connection.
    An adversary may place a network interface into promiscuous mode to passively access data in transit over the network, or use span ports to capture a larger amount of data.
