The file is identified as malicious by ClamAV as Win.Dropper.HawkEye-10021144-0. Static analysis revealed an embedded OLE object containing an executable payload, indicating an attempt to exploit CVE-2026-21514. The document body contains a prompt to 'Click to Download Tracking Reference', further suggesting a lure to download and execute the embedded malicious file.

Heuristics 7

  • OOXML Ole10Native with payload/link indicators — possible CVE-2026-21514 high CVE likely CVE_2026_21514
    Office document contains embedded OLE (word/embeddings/oleObject1.bin) with Ole10Native plus executable, PE, or risky remote-link indicators. This is a likely CVE-2026-21514 exploitation shape.
  • Ole10Native package drops an auto-executable payload critical OFFICE_PACKAGE_RISKY_FILE
    OLE Package displayName or fullPath ends in a directly auto-executable extension (a runnable binary or a script the default shell host runs on double-click). Embedding such a payload inside an Office document has no benign authoring use — it is a malware-delivery dropper.
  • ClamAV: Win.Dropper.HawkEye-10021144-0 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Win.Dropper.HawkEye-10021144-0
  • ClamAV detection on extracted artifact critical EXTRACTED_FILE_CLAMAV
    ClamAV flagged at least one file extracted from inside this sample. Even when the wrapping document carries no AV detection of its own, a hit on the carved artifact is a strong indicator the sample is a delivery vehicle.
  • Embedded OLE object medium OOXML_OLE_OBJECT
    Document contains an embedded OLE object
  • Suspicious extracted artifact info 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.
  • 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.
