MITRE ATT&CK

T1203 Exploitation for Client Execution

The sample leverages the CVE-2017-0199 vulnerability, which allows for remote code execution via OLE2Link and URL Moniker objects. This technique is used to download a secondary payload from the specified URL. Although VBA macros are present, they do not contain executable statements, suggesting the exploit is directly triggered by the OLE object rather than macro execution.

Heuristics 3

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.
VBA project contains no executable statements low OLE_VBA_MACROS

Document contains a VBA project, but extracted modules only contain attributes/options/comments and no executable statements.
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.

URL http://000000000015353773003/00000000000000000001.php
