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

The file contains a legacy WordBasic AutoOpen macro, indicated by the OLE_LEGACY_WORDBASIC_AUTOEXEC heuristic. This macro is designed to execute automatically when the document is opened. The presence of 'Terror...' in the document body and the ClamAV detection as 'Win.Trojan.Terror-7' strongly suggest malicious intent. The macro likely attempts to download or execute a secondary payload, potentially using the C:\terror.dot path as a dropped file or configuration.

Heuristics 2

  • ClamAV: Win.Trojan.Terror-7 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Win.Trojan.Terror-7
  • 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.
