MITRE ATT&CK

T1566.001 Spearphishing Attachment T1203 Exploitation for Client Execution

The sample exhibits characteristics of a malicious OOXML document, specifically remote template injection and the presence of an embedded OLE object. The embedded OLE object and remote template injection are likely used to download and execute a secondary payload from the unknown URL. The document body was truncated and did not provide further context on the lure.

Heuristics 4

Remote template injection high OOXML_REMOTE_TEMPLATE

Document references a remote template URL (https://wrath.me/HXwkrG) — 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://wrath.me/HXwkrG
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.
