MITRE ATT&CK
T1059.005 Visual Basic

The sample exhibits legacy WordBasic macro virus markers, specifically 'RSN MACRO VIRUS', and includes embedded text that appears to be part of a game or prank macro. The presence of these markers and the game-like content strongly suggest a malicious intent, likely to execute further malicious code via the macro when enabled. No specific family could be identified, but the technique points to older macro-based threats.

  • 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.
