This PowerPoint file contains a VBA macro that is automatically executed upon opening, indicated by the Auto_Open heuristic. The GetObject call within the macro suggests it is designed to load and execute external code. While no specific URLs or hashes were extracted, the presence of a VBA macro with auto-execution capabilities strongly points to a downloader or initial execution stage for a malicious payload. The macro's complexity and obfuscation are not detailed, but its presence and execution method are clear indicators of malicious intent.

Heuristics 5

  • Auto_Open macro high OLE_VBA_AUTO
    Auto_Open macro
  • GetObject call high OLE_VBA_GETOBJ
    GetObject 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
  • Suspicious extracted artifact info EXTRACTED_FILE_STATIC_TRIAGE
    One or more files extracted from inside this sample matched static suspicious-content checks such as script obfuscation, encoded payload blobs, packed data, or execution/download terms.
