MITRE ATT&CK
T1203 Exploitation for Client Execution T1566.001 Spearphishing Attachment

The RTF file contains a critical heuristic indicating remote template injection, targeting the URL http://domhub.live/arm/template.php. This suggests the document is designed to exploit a vulnerability to download and execute a secondary payload from this external resource. The presence of this malicious indicator strongly points towards an attack vector commonly used for malware delivery.

Heuristics 2

  • Remote template injection (\*\template → remote URL) critical CVE related RTF_REMOTE_TEMPLATE
    The RTF's \*\template destination is a remote URL/UNC path. When Word opens the document it fetches and loads that template, which can carry macros or an exploit, deliver a scriptlet/HTA, or leak NTLM credentials over UNC. Benign documents attach only a local template, so a remote \*\template target is template-injection delivery (MITRE T1221). remote \*\template target (Word fetches it on open); destination obfuscated with \uN/\'xx escapes; dynamic-DNS / abuse-prone host; target is active/script content, not a .dot template.
  • 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.
