MITRE ATT&CK

T1059.005 Visual Basic T1059.001 PowerShell

The file is a PowerPoint presentation containing VBA macros. High-severity heuristics indicate the presence of an Auto_Close macro that uses the Shell function for execution. This suggests the macro is designed to run an external command upon closing the presentation, likely to download and execute a secondary payload. No specific family could be identified, and no external IOCs were extracted.

Heuristics 3

Auto_Close macro high OLE_VBA_AUTOCLOSE

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

Document contains VBA macro code
