MITRE ATT&CK
T1059.005 Visual Basic

The sample exhibits characteristics of a legacy macro virus, specifically identified by 'RSN MACRO VIRUS' markers and the presence of WordBasic macro functions like AutoOpen and AutoExec. The document body contains obfuscated text and file paths, suggesting an attempt to hide malicious intent. While no specific payload delivery mechanism is evident, the macro functions indicate potential for arbitrary code execution.

  • ClamAV: Win.Trojan.Stall-1 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Win.Trojan.Stall-1
  • 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.
