MITRE ATT&CK
T1204.002 Malicious File T1559.001 Component Object Model Hijacking

The file exhibits characteristics of a malicious OOXML document, specifically remote template injection and the presence of an embedded OLE object. The URL 'https://zeep.ly/calnj' is associated with these findings and likely serves as a lure or download source for a secondary payload. The embedded OLE object, identified as 'ooxml_oleobject_00.bin', is a strong indicator of malicious intent, often used to host or execute further stages of an attack.

Heuristics 5

  • Remote template injection high OOXML_REMOTE_TEMPLATE
    Document references a remote template URL (https://zeep.ly/calnj) — 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://zeep.ly/calnj
  • 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.
