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

The sample is a legacy Word document containing WordBasic macros, indicated by the 'OLE_LEGACY_WORDBASIC_AUTOEXEC' heuristic firing on the 'AutoOpen' marker. This macro is designed to execute automatically when the document is opened, a common technique for delivering malware. The presence of 'Win.Trojan.Tele-1' in the ClamAV detection further confirms its malicious nature. The document body contains strings like 'LUCIFER.DOC' and 'TELEFONICA' which may be related to the payload or its distribution.

Heuristics 2

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