MITRE ATT&CK

T1566.001 Spearphishing Attachment T1203 Exploitation for Client Execution T1027 Obfuscated Files or Information

The file exhibits characteristics of a malicious document, including remote template injection and external relationships pointing to the URL https://ccurl.xyz/Jdbn. It also contains embedded OLE objects, suggesting an attempt to execute malicious code or exploit vulnerabilities. The primary attack vector appears to be a spearphishing attachment designed to lure the user into opening a document that then attempts to download and execute further payloads.

Heuristics 4

Remote template injection high OOXML_REMOTE_TEMPLATE

Document references a remote template URL (https://ccurl.xyz/Jdbn) — 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://ccurl.xyz/Jdbn
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.
