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

The sample contains legacy WordBasic macros, specifically an AutoOpen macro, which is a strong indicator of malicious intent. The document body displays a fake error message to lure the user, and the macro is configured to execute a file named '1.com' from the Windows directory, likely a second-stage payload. The ClamAV detection name 'Win.Trojan.StupidVir-1' further supports the malicious classification.

Heuristics 2

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