MITRE ATT&CK
T1059.005 Visual Basic

The sample exhibits characteristics of legacy macro viruses, including WordBasic markers and VBA macros. The 'SHOGUN' VBA macro contains a message box that displays a personal message and includes code to disable virus protection and prompt for saving. While the message content is personal, the disabling of security features and the presence of legacy macro virus markers suggest malicious intent.

Heuristics 5

  • ClamAV: Legacy.Trojan.Agent-34741 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Legacy.Trojan.Agent-34741
  • Legacy WordBasic macro-virus markers high OLE_LEGACY_WORDBASIC_MACRO_VIRUS
    OLE Word document contains legacy WordBasic auto-execution macro markers such as AutoOpen plus ToolsMacro/MacroFile/fileMacro/globMacro or named historical macro-virus strings. These old Word 6/95 macro forms are not exposed as a modern VBA project, so normal VBA source extraction can miss them.
  • VBA macros detected medium 2 related findings OLE_VBA_MACROS
    Document contains VBA macro code
  • AutoOpen macro high OLE_VBA_AUTOOPEN
    AutoOpen macro
  • Auto_Close macro high OLE_VBA_AUTOCLOSE
    Auto_Close macro
