SloppyRAT PSInline CLR-based PowerShell Execution via COM
Detects the loading of .NET Common Language Runtime (clr.dll) and System.Management.Automation.dll into a process that is not a recognized PowerShell binary (e.g., powershell.exe, pwsh.exe). This behavior is associated with the 'PSInline' technique used by SloppyRAT, where PowerShell capabilities are invoked directly via COM objects to execute commands in memory. The rule further correlates this activity with the creation of files with a .png extension in temporary directories, which is consistent with the exfiltration staging behavior of the malware.
