Detects the execution of obfuscated PowerShell commands that attempt to install MSI packages via the Windows Installer COM object (WindowsInstaller.Installer). The technique involves manipulating strings to hide functionality, such as constructing class names using string insertion (e.g., 'indowsInstaller.Installer'.Insert(0,'W')) and correcting malformed URLs (e.g., converting 'htps://' to 'https://') at runtime. This behavior is commonly associated with malware loaders or droppers that aim to bypass static detection by hiding intent in runtime-generated strings and using legitimate tools for code execution. The use of InstallProduct and COM object creation, particularly combined with hidden window execution and suppressed UI, indicates an attempt to install software (likely malicious) without user interaction.

To detect suspicious use of msiexec.exe by Raspberry Robin or other threats, it’s essential to take a look at the command line and the URL. Detecting msiexec.exe making outbound network connections to download and install packages in the command-line interface will give you the opportunity to examine the activity and determine if it’s malicious or not.
