T1059.005 Visual Basic T1059.001 PowerShell T1204.002 Malicious File

The sample is a PowerPoint file with a high-confidence detection for VBA macros, specifically an Auto_Close macro that utilizes CreateObject. This indicates the macro is designed to execute code automatically when the presentation is closed. The presence of VBA p-code auto-execution further supports this. No specific IOCs like URLs or hashes were extracted, but the technique strongly suggests a downloader or initial execution stage.

Heuristics 4

Auto_Close macro high OLE_VBA_AUTOCLOSE

Auto_Close macro
CreateObject call high OLE_VBA_CREATEOBJ

CreateObject 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
