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

The file is an OLE document containing legacy WordBasic macros, indicated by the 'autoclose' marker and the ClamAV detection of 'Win.Trojan.Dirty-2'. The document body is a fabricated job application, a common lure for social engineering. The presence of legacy macros suggests an attempt to execute code upon opening, likely to download and execute a secondary payload.

Heuristics 2

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