PowerShell LOLBAS Execution with Public Network Connection
This rule detects PowerShell processes that are initiated by a LOLBAS binary and subsequently establish an outbound network connection to a public IP address. It leverages an external LOLBAS JSON data source to identify suspicious parent processes. This behavior could indicate an adversary using a Living Off The Land Binary or Script (LOLBAS) to execute PowerShell for malicious purposes, such as command and control or data exfiltration.
