MITRE ATT&CK

T1566.001 Spearphishing Attachment T1203 Exploitation for Client Execution

The OOXML document contains heuristics indicating remote template injection and external relationships, pointing to the use of a malicious external resource. The embedded OLE object and extracted artifacts suggest the file is designed to deliver a secondary payload. The primary IOC is the suspicious URL referenced in multiple heuristics.

Heuristics 5

Remote template injection high OOXML_REMOTE_TEMPLATE

Document references a remote template URL (https://jktc.pro/WHtKBb?&friction=vague&vein=miscreant&craftsman=gleaming&bug=flippant&mantel=upbeat&pew) — 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://jktc.pro/WHtKBb?&friction=vague&vein=miscreant&craftsman=gleaming&bug=flippant&mantel=upbeat&pew
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.
