MITRE ATT&CK

T1204.002 Malicious File: User Execution T1059.001 PowerShell

The critical heuristic firing indicates the exploitation of CVE-2017-0199 via an OLE2Link object, which attempts to load a remote resource. The embedded URL, http://OASOSIDFOSWEROEROOWRWERWEREWWW0W83W338W83WOIE33RR333R3R3R3333RRR33UU3U3UR8E8E8E8E833RERERER3R3R3333RRR3333RR33RRR33R33@172.245.123.113/32.....................32...............doc, is the primary indicator of this malicious activity. This suggests the file acts as a downloader for a secondary 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.
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.
