MITRE ATT&CK
T1204.002 Malicious File

The sample exhibits characteristics of a malicious OOXML document, specifically remote template injection and the presence of an external relationship pointing to a suspicious URL. The heuristic 'OOXML_REMOTE_TEMPLATE' firing with the URL 'https://wonderfullworkingskillgivenbestfeelingswithbestresturnsofthebestthingtthworking.dOcX=@link.emcdn.ru/QiRe6L' strongly suggests the document is designed to fetch and execute content from this external source. The embedded OLE object further supports the malicious nature of the file.

Heuristics 4

  • Remote template injection high OOXML_REMOTE_TEMPLATE
    Document references a remote template URL (https://wonderfullworkingskillgivenbestfeelingswithbestresturnsofthebestthingtthworking.dOcX=@link.emcdn.ru/QiRe6L) — 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://wonderfullworkingskillgivenbestfeelingswithbestresturnsofthebestthingtthworking.dOcX=@link.emcdn.ru/QiRe6L
  • 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.
