PowerShell Store File In Alternate Data Stream via Comspec
This rule detects PowerShell commands that attempt to store data in an Alternate Data Stream (ADS) by redirecting the output of a command executed via `cmd.exe` (comspec) into a file using the `>` operator. This technique is often used by malware, such as Astaroth, to hide malicious data within legitimate files, making it harder to detect.
