What it detects

This rule detects PowerShell script content invoking the Get-ComputerInfo cmdlet to enumerate detailed system information. A threat actor abusing a free Elastic Cloud SIEM trial ran this command to profile compromised hosts before exfiltrating the results, so its appearance in encoded or automated PowerShell is an early indicator of system discovery ahead of data theft.
