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

The critical heuristic firing indicates exploitation of CVE-2017-0199 via an OLE2Link object, which is designed to load remote content. The embedded URL, https://ir.cx/iVUhW, is highly suspicious and likely serves as a loader for a secondary stage payload. This indicates a classic remote code execution and download-and-execute attack pattern.

Heuristics 1

  • 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.
