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 content. The document body attempts to impersonate a virus protection system to deter user interaction or deletion, a common social engineering tactic. The primary technique observed is the use of Visual Basic for Applications (VBA) macros to execute malicious code.

  • ClamAV: Win.Trojan.MG-7 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Win.Trojan.MG-7
  • 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.
