T1059.005 Visual Basic

The sample is identified as malicious by ClamAV with the signature Win.Trojan.Gier-1. Legacy WordBasic auto-execution markers (AutoClose) were detected, suggesting the execution of malicious code upon document interaction. The presence of these legacy macros indicates a potential for system compromise through automated execution.

Heuristics 2

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