MITRE ATT&CK
T1059.005 Visual Basic

The sample exhibits characteristics of a legacy WordBasic macro virus, specifically identified by the 'ToolsMacro' marker and ClamAV detection as Win.Trojan.Kilok-2. The document body contains text referencing a virus named 'KraKAtAudk' and includes a URL, suggesting a social engineering or distribution attempt. The presence of legacy macro virus markers points to the use of Visual Basic for macro execution.

Heuristics 3

  • ClamAV: Win.Trojan.Kilok-2 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Win.Trojan.Kilok-2
  • 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.
  • Embedded URL info EMBEDDED_URL
    One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
