MITRE ATT&CK
T1059.005 Visual Basic

The sample contains a legacy WordBasic auto-exec macro marker (AutoOpen), indicating an attempt to execute malicious code upon opening. ClamAV detection as 'Doc.Trojan.MVDK-1' further confirms its malicious nature. The document body appears to be a timesheet template, likely a lure to disguise the macro execution.

Heuristics 2

  • ClamAV: Doc.Trojan.MVDK-1 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Doc.Trojan.MVDK-1
  • Legacy WordBasic auto-exec macro marker medium OLE_LEGACY_WORDBASIC_AUTOEXEC
    OLE Word document contains a legacy WordBasic auto-execution marker such as AutoOpen, but no modern VBA project was recovered and no stronger macro-virus family marker was present. This is analyst-facing evidence for old Word macro execution surface, not a downloader or parser-CVE attribution by itself.
