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

The sample is identified as malicious by ClamAV with the signature Win.Trojan.Black-3. It contains legacy WordBasic macros, specifically an AutoOpen macro, which is a known technique for executing malicious code upon document opening. The presence of strings like 'BlackDeath' and 'C:\BlackDeath.doc' suggests a potential payload or infection path.

  • 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.
