MITRE ATT&CK
T1566.001 Spearphishing Attachment

The OOXML document contains heuristics indicating remote template injection and external relationship usage, pointing to a malicious URL. This suggests the document is designed to lure the user into downloading and executing a secondary payload from the specified URL. The primary attack vector is likely spearphishing attachment.

Heuristics 3

  • Remote template injection high OOXML_REMOTE_TEMPLATE
    Document references a remote template URL (http://apidevops.org/FaGx/I/shNkj2c2p6GK8TgcJrVhwJDkAAAB6H6SCmNp21cqG/RLnXiB24cRS0jkrR3OU6mNBg7jbMEfD7nthTx05HvUnpntv7qX4g7MCQWVvE8c=) — 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://apidevops.org/FaGx/I/shNkj2c2p6GK8TgcJrVhwJDkAAAB6H6SCmNp21cqG/RLnXiB24cRS0jkrR3OU6mNBg7jbMEfD7nthTx05HvUnpntv7qX
  • 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.
