MITRE ATT&CK
T1059.001 PowerShell

The file exhibits high-confidence heuristics for Windows Script Host usage and VBA auto-execution, indicating an attempt to run malicious code. Although VBA macros could not be fully extracted, the presence of these indicators, combined with multiple unknown reputation URLs, strongly suggests a downloader or droppper functionality. The ClamAV detection as 'Doc.Downloader.ChristmasGift' further supports this assessment.

Heuristics 5

  • ClamAV: Doc.Downloader.ChristmasGift-9845923-0 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Doc.Downloader.ChristmasGift-9845923-0
  • Reference to Windows Script Host high SC_STR_WSCRIPT
    Reference to Windows Script Host
  • 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.
  • Unsupported Office format for VBA extraction info OFFICE_FORMAT_UNSUPPORTED
    olevba could not extract VBA macros (AssertionError); format-agnostic byte-level scans still ran. Likely legacy, encrypted, or malformed OLE/OOXML — re-scanning the same bytes will yield the same outcome.
  • 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.
