MITRE ATT&CK

T1204.002 Malicious File: User Execution T1059.005 PowerShell T1071.001 Web Protocols: HTTP

The critical heuristic firing indicates exploitation of CVE-2017-0199 via an OLE2Link object, which attempts to load a remote document from the URL 'https://greatsigngivenmebestthingswithgoodnewsgivenmebestwayfor.doc@grsh.link/oMwXSY'. Although the VBA macros themselves contain no executable statements, the presence of the OLE2Link exploit strongly suggests the file's purpose is to act as a downloader for a secondary malicious payload.

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
