MITRE ATT&CK
T1059.005 Visual Basic T1566.001 Spearphishing Attachment

The sample is an OLE document from 1995, flagged by ClamAV as Win.Trojan.Atom-8. A legacy WordBasic auto-exec macro marker, FileSaveAs, was detected, indicating the potential for automatic execution of malicious code upon opening. This suggests a macro-based downloader attack vector.

Heuristics 2

  • ClamAV: Win.Trojan.Atom-8 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Win.Trojan.Atom-8
  • 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.
