MITRE ATT&CK

T1204.002 Malicious File: User Execution: Malicious File

The sample exhibits characteristics of a malicious OOXML document, specifically remote template injection and external relationships pointing to 'https://obdr.it/PenEm'. It also contains embedded OLE objects, suggesting an attempt to deliver a secondary payload or exploit. The presence of these indicators strongly implies an attack pattern focused on exploiting document vulnerabilities to execute malicious code.

Heuristics 5

Remote template injection high OOXML_REMOTE_TEMPLATE

Document references a remote template URL (https://obdr.it/PenEm) — 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://obdr.it/PenEm
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.
