MITRE ATT&CK

T1559.001 Component Object Model Hijacking

The document contains an embedded PE executable, identified by an MZ header. This executable is likely the primary payload. The heuristic 'OLE_EMBEDDED_EXE' strongly indicates the presence of a malicious executable embedded within the OLE structure. The document body's instruction to 'Apri l'immagine sotto con un doppio-click' (Open the image below with a double-click) is a social engineering lure to trick the user into executing the embedded file.

Heuristics 4

OLE with Ole10Native — possible CVE-2026-21514 exploitation high CVE likely CVE_2026_21514

Document contains a Word OLE object with Ole10Native plus executable, PE, or risky remote-link indicators. CVE-2026-21514 exploits OLE metadata validation; this stronger structure is treated as likely exploitation.
Embedded PE executable critical OLE_EMBEDDED_EXE

MZ/PE header found inside document — possible embedded executable
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.
