MITRE ATT&CK
T1059.005 Visual Basic T1204.002 Malicious File T1059 Command and Scripting Interpreter

The PowerPoint file contains VBA macros, specifically an Auto_Close subroutine that calls a Calculator_Click subroutine. This subroutine uses the Shell() function to execute a string that appears to be a reversed URL. The reconstructed URL is "https://sm.pm\:sptth\\7qraem63x01yxiw". This indicates the macro is designed to download and execute a second-stage payload.

Heuristics 5

  • 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
  • Macro capabilities present but unconfirmed info MACRO_CAPABILITY_UNCORROBORATED
    The document's VBA exposes execution capabilities (Shell/WScript/CreateObject/auto-exec) but nothing corroborates malicious intent — no obfuscation, memory-exec primitive, download+exec chain, encoded payload, LOLBin, DDE, AV hit, or suspicious URL. The verdict was capped at 'suspicious' so legitimate macro-heavy business documents are not flagged malicious on capability presence alone.
