MITRE ATT&CK
T1566.001 Spearphishing Attachment

The document's heuristics indicate it is designed as a fake invoice or payment lure. While the document body is heavily obfuscated and unreadable, the presence of these heuristics strongly suggests a social engineering attempt to trick the user into performing an action, likely related to payment or a financial transaction. No scripts or further IOCs were extracted to confirm the exact payload or delivery mechanism.

Heuristics 2

  • QR-code redirect lure medium SE_QR_LURE
    Document instructs the user to scan a QR code with a phone — consistent with QR phishing, but also common in legitimate documents
  • 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.
