MITRE ATT&CK
T1566.001 Spearphishing Attachment T1203 Exploitation for Client Execution T1105 Ingress Tool Transfer

The file is identified as a malicious dropper by ClamAV, specifically Win.Dropper.HawkEye-8996760-0. It contains an embedded OLE object that likely exploits CVE-2026-21514 to drop an executable payload. The embedded URLs, while benign in this context, are associated with the OLE object, suggesting a potential download mechanism for the payload.

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.
  • ClamAV: Win.Dropper.HawkEye-8996760-0 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Win.Dropper.HawkEye-8996760-0
  • 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.
  • Embedded OLE object medium OOXML_OLE_OBJECT
    Document contains an embedded OLE object
  • Suspicious extracted artifact medium 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.
  • Payload URL recovered from embedded OLE object (8 URLs) info OOXML_EMBEDDED_OBJECT_URL
    An embedded OLE object (xl/word/ppt embeddings) carries a next-stage download URL in its Ole10Native/Package stream — stored literally (incl. UTF-16) or base64-encoded — which the package-level URL sweep does not see. Surfaced as an IOC; self-validating (only real payload hosts).
  • 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.
