MITRE ATT&CK
T1059.001 PowerShell T1566.001 Spearphishing Attachment

The critical ClamAV detection and high-severity heuristics for VBA macros, including auto-execution and CreateObject calls, strongly indicate malicious intent. The presence of a Document_Open macro suggests an attempt to automatically execute code upon opening the document. The extracted ClamAV signature 'Doc.Downloader.Logan-9781905-0' points to a downloader functionality, likely responsible for fetching and executing a secondary payload.

Heuristics 7

  • ClamAV: Doc.Downloader.Logan-9781905-0 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Doc.Downloader.Logan-9781905-0
  • Document_Open macro high OLE_VBA_DOCOPEN
    Document_Open macro
  • CreateObject call high OLE_VBA_CREATEOBJ
    CreateObject call
  • 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.
  • Suspicious extracted artifact high EXTRACTED_FILE_STATIC_TRIAGE
    One or more files extracted from inside this sample matched static suspicious-content checks such as script obfuscation, encoded payload blobs, packed data, or execution/download terms.
  • VBA macros detected medium OLE_VBA_MACROS
    Document contains VBA macro code
  • 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.
