MITRE ATT&CK
T1059.005 Visual Basic

The file is an OLE document containing legacy WordBasic macros, indicated by the 'AutoOpen' marker. ClamAV identifies it as Win.Trojan.Wannabe-1. The presence of an auto-executing macro suggests an attempt to run malicious code upon opening the document, likely for payload delivery.

Heuristics 2

  • ClamAV: Win.Trojan.Wannabe-1 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Win.Trojan.Wannabe-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.
