The presence of VBA macros, specifically an Auto_Close macro that calls the Shell() function, indicates malicious intent. The critical heuristic firing for OLE_VBA_SHELL confirms the execution of arbitrary commands. This suggests the macro is designed to download and execute a secondary payload, a common technique for initial access or further system compromise. No specific family could be identified from the available evidence.

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
