MITRE ATT&CK
T1204.002 Malicious File: User Execution

The sample exhibits characteristics of a malicious OOXML document, specifically triggering heuristics for remote template injection and external relationships pointing to a suspicious URL. The presence of an embedded OLE object further suggests an attempt to execute malicious code. The primary IOC is the URL used for remote template injection, which is a common technique for delivering secondary payloads.

Heuristics 5

  • Remote template injection high OOXML_REMOTE_TEMPLATE
    Document references a remote template URL (https://whenagirltrytobreakyourheartwithbestfeelingtheywillnotknowwhattheydoing.dOcX=@link.emcdn.ru/ICGrzC) — 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://whenagirltrytobreakyourheartwithbestfeelingtheywillnotknowwhattheydoing.dOcX=@link.emcdn.ru/ICGrzC
  • Embedded OLE object medium OOXML_OLE_OBJECT
    Document contains an embedded OLE object
  • Suspicious extracted artifact info EXTRACTED_FILE_STATIC_TRIAGE
    One or more files extracted from inside this sample matched static suspicious-content checks such as script obfuscation, encoded payload blobs, packed data, or execution/download terms.
  • 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.
