MITRE ATT&CK
T1566.001 Spearphishing Attachment

The file is an OOXML document that uses a remote template injection heuristic, indicating it attempts to load external content from 'http://hidfes.bounceme.net/basic/register/baseball/precarious/kFEkds.dot'. This is a common technique for downloading and executing further malicious stages. No scripts were extracted, but the presence of the remote template strongly suggests a malicious intent, likely related to phishing or malware delivery.

Heuristics 3

  • Remote template injection high OOXML_REMOTE_TEMPLATE
    Document references a remote template URL (http://hidfes.bounceme.net/basic/register/baseball/precarious/kFEkds.dot) — 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://hidfes.bounceme.net/basic/register/baseball/precarious/kFEkds.dot
  • 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.
