MITRE ATT&CK
T1059.005 Visual Basic T1059.001 PowerShell

The file is a PowerPoint presentation containing VBA macros. A critical heuristic firing indicates the use of the Shell() function, which is commonly used to execute arbitrary commands. The Auto_Close macro is also present, suggesting that the malicious code may execute when the presentation is closed. No specific malware family could be identified, but the techniques used are consistent with macro-based malware delivery. The embedded URL was confirmed as benign and is not included as an IOC.

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
  • Embedded URL info EMBEDDED_URL
    One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
