MITRE ATT&CK
T1059.005 Visual Basic

The sample exhibits characteristics of a legacy macro virus, specifically identified by 'RSN MACRO VIRUS' markers within its document body and heuristic firings. The embedded text, including file paths and function names like 'AutoOpen', suggests an attempt to execute malicious code upon opening. While the specific family is not identifiable, the presence of these markers strongly indicates a macro-based threat.

  • 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.
