MITRE ATT&CK
T1059.005 Visual Basic T1566.001 Spearphishing Attachment T1204.002 Malicious File

The sample contains VBA macros, including an AutoOpen macro that executes a script. This script writes obfuscated content from the document body to a file named '.HTA' and then executes it using 'scriptrunner -appvscript .HTA'. This indicates a downloader or dropper functionality, likely to fetch and execute a second-stage payload.

Heuristics 6

  • ClamAV: Doc.Downloader.BlueOffice08210-9889818-0 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Doc.Downloader.BlueOffice08210-9889818-0
  • AutoOpen macro high OLE_VBA_AUTOOPEN
    AutoOpen macro
  • VBA p-code auto-exec with execution tokens high OLE_VBA_PCODE_AUTOEXEC_EXEC
    Compiled VBA/cache stream contains an auto-execution token together with shell/download/object-execution tokens. This catches p-code-only or source-extraction-failure macro documents where visible source is unavailable.
  • VBA macros detected medium OLE_VBA_MACROS
    Document contains VBA macro code
  • Macro/content-enable lure medium SE_ENABLE_LURE
    Document instructs the user to enable macros or editing — a common technique used by malware droppers to bypass Office macro security settings
  • Embedded URL info EMBEDDED_URL
    One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
