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

The critical heuristic firing indicates the exploitation of CVE-2017-0199, which is a known vulnerability used to download and execute remote code. The embedded URL is the primary indicator of the remote payload's source. The file is an OLE2Link object, commonly used in such exploits.

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.
