MITRE ATT&CK

T1204.002 Malicious File: User Execution T1059.005 Service Execution: Visual Basic

The critical heuristic firing indicates the exploitation of CVE-2017-0199 via an OLE2Link object, which is designed to download and execute a remote loader from the provided URL. Although no VBA macros were found to be executable, the presence of the OLE vulnerability strongly suggests a malicious intent to compromise the user's system.

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.
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.
