MITRE ATT&CK
T1566.001 Spearphishing Attachment

The OOXML document contains an external relationship pointing to 'http://51.11.240.201/word.html'. This heuristic firing, combined with the MSHTML-style external object, strongly suggests the document is designed to fetch and potentially execute content from this remote URL. The document's purpose is likely to act as a downloader for a secondary stage payload.

Heuristics 3
