MITRE ATT&CK
T1566.001 Spearphishing Attachment

The OOXML document was flagged for remote template injection and external relationship, indicating it attempts to load content from the URL http://apo.palenc.club:2095/dcs/sd8/sd8.dotm. This is a common technique for downloading and executing secondary payloads. No scripts were extracted, but the heuristics strongly suggest a malicious intent to compromise the user's system.

Heuristics 3

  • Remote template injection high OOXML_REMOTE_TEMPLATE
    Document references a remote template URL (http://apo.palenc.club:2095/dcs/sd8/sd8.dotm) — 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: http://apo.palenc.club:2095/dcs/sd8/sd8.dotm
  • 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.
