MITRE ATT&CK

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

The presence of VBA macros, specifically an Auto_Close macro that calls the Shell() function, indicates that this PowerPoint file is designed to execute arbitrary code upon opening or closing. This is a common technique for downloading and executing further malicious payloads. The critical heuristic firing for Shell() call in VBA and the high heuristic firing for p-code auto-execution with execution tokens strongly support this conclusion. No specific IOCs were extracted, but the attack pattern is clear.

Heuristics 4

Shell() call in VBA critical OLE_VBA_SHELL

Shell() call in VBA
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
