Gamaredon VBScript-to-PowerShell multi-stage payload chain via OUTLOOK
Detects execution chains where Outlook launches a VBScript file that subsequently invokes PowerShell with encoded commands, characteristic of Gamaredon (ACTINIUM) threat activity. Additionally, it identifies the creation of VBScript/VBE files in temporary directories, which is consistent with the deployment of PteroVDoor or PteroPSDoor loaders.
