MITRE ATT&CK
T1059.005 Visual Basic

The sample is identified as malicious by ClamAV with the signature Win.Trojan.Epidemic-2. A legacy WordBasic AUTOOPEN macro was detected, indicating that malicious code is likely executed automatically when the document is opened. The presence of the AUTOOPEN marker and the file path 'C:\My Documents\Epidemic.doc' are the primary indicators.

Heuristics 2

  • ClamAV: Win.Trojan.Epidemic-2 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Win.Trojan.Epidemic-2
  • 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.
