MITRE ATT&CK

T1204 Malicious Link

The OOXML document contains heuristics indicating remote template injection and an external relationship pointing to https://come.to/fixitdatatransfer. This suggests the document is designed to lure the user into downloading and executing a malicious payload from the specified URL, likely leading to further compromise.

Heuristics 4

Remote template injection high OOXML_REMOTE_TEMPLATE

Document references a remote template URL (https://come.to/fixitdatatransfer) — a common remote-template-injection vector used by Hancitor, Emotet and many phishing campaigns. Word can fetch and apply the remote template; macros in that template may execute depending on Office policy and trust state.
External relationship medium OOXML_EXTERNAL_REL

External target in word/_rels/settings.xml.rels: https://come.to/fixitdatatransfer
Embedded OLE object medium OOXML_OLE_OBJECT

Document contains an embedded OLE object
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.
