MITRE ATT&CK

T1566.001 Spearphishing Attachment T1203 Exploitation for Client Execution

The OOXML document exhibits characteristics of malicious intent, specifically remote template injection and external relationships pointing to the URL https://urlty.co/gZTJU. The presence of embedded OLE objects further suggests the potential for executing embedded code. These indicators collectively point towards an attack pattern designed to download and execute a secondary payload, likely via a spearphishing attachment.

Heuristics 4

Remote template injection high OOXML_REMOTE_TEMPLATE

Document references a remote template URL (https://urlty.co/gZTJU) — 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://urlty.co/gZTJU
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.
