Windows Cabinet File Extraction Via Expand
Detects usage of expand.exe to extract Microsoft Cabinet (CAB) archives, with emphasis on extractions into `C:\\ProgramData` or similar staging locations. In recent APT37 activity, a CAB payload (e.g., wonder.cab) was expanded into ProgramData prior to persistence and execution. This behavior is a strong signal for ingress tool transfer and staging of payloads.
