MITRE ATT&CK
T1059.005 Visual Basic

The sample exhibits characteristics of a legacy WordBasic macro virus, specifically the presence of 'fileMacro$' and autoOpen routines. These elements suggest an attempt to execute malicious code upon opening the document, likely to download or execute a secondary payload. The ClamAV detection as Win.Trojan.Wazzu-30 further supports its malicious nature.

Heuristics 2

  • ClamAV: Win.Trojan.Wazzu-30 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Win.Trojan.Wazzu-30
  • 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.
