The presence of a high-severity OLE_VBA_AUTOCLOSE heuristic indicates the use of an Auto_Close macro, which is a common technique for executing malicious code upon document closure. The OLE_VBA_PCODE_AUTOEXEC_EXEC heuristic further confirms that a VBA p-code auto-execution is used with the 'Shell' function, suggesting the macro attempts to run an external command. This is likely intended to download and execute a second-stage payload. No specific family could be identified.

Heuristics 3

Auto_Close macro
VBA p-code auto-exec with execution tokens high OLE_VBA_PCODE_AUTOEXEC_EXEC

Compiled VBA/cache stream contains an auto-execution token together with shell/download/object-execution tokens. This catches p-code-only or source-extraction-failure macro documents where visible source is unavailable.
VBA macros detected medium OLE_VBA_MACROS
