MITRE ATT&CK
T1204.002 Malicious File: User Execution

The sample is a malicious OLE document that leverages the CVE-2017-0199 vulnerability. This vulnerability allows the document to act as a remote loader, fetching and executing a payload from the embedded URL: https://www.xmlformats.com/office/word/2022/wordprocessingDrawing/RDF842l.html. The document body contains obfuscated data and references to VBA, indicating potential for further malicious scripting.

Heuristics 2

  • OLE2Link / URL Moniker → remote loader — CVE-2017-0199 critical CVE likely CVE_2017_0199
    Document contains an embedded OLE link object whose URL Moniker points to a remote URL. When the host file is opened, Office follows the link, downloads the URL, and processes the response based on its Content-Type (HTA -> mshta.exe, RTF → Word, etc.) — the documented CVE-2017-0199 primitive. The URL extension is not a reliable filter; servers can return different payloads to Office's user agent.
  • 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.
