MITRE ATT&CK
T1204.002 Malicious File

The RTF file contains a critical heuristic indicating remote template injection, pointing to a suspicious URL. This suggests the file is designed to download and execute a secondary payload from the specified address. The document body is heavily obfuscated and does not provide clear user-facing content, reinforcing the malicious intent.

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); 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.
