MITRE ATT&CK

T1059.005 Visual Basic T1059.001 PowerShell

The presence of an Auto_Open macro and a GetObject call strongly indicates malicious intent. The Auto_Open macro is automatically executed upon opening the presentation, and the GetObject call is often used to instantiate and execute objects, likely to download and run a second-stage payload. No specific family could be identified from the available heuristics.

Heuristics 4

Auto_Open macro high OLE_VBA_AUTO

Auto_Open macro
GetObject call high OLE_VBA_GETOBJ

GetObject call
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

Document contains VBA macro code
