The OOXML document contains high-severity heuristics indicating remote template injection and external relationship exploitation. These point to the document's primary function of downloading and executing a second-stage payload from the embedded URL. The presence of a visible LOLBin command execution instruction further supports this malicious intent.

Heuristics 4

  • Remote template injection high OOXML_REMOTE_TEMPLATE
    Document references a remote template URL (https://www.mail-sender.online/it-it?t=eyJhbGciOiJIUzI1NiJ9.eyJ0cmFja2luZ190b2tlbiI6IjhkZjI3NmYwLWU5NzQtNDM1OC1hNzMzLTcxNWY0YWJmNTNjMyIsImNl) — 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.
  • Visible LOLBin command execution instruction high SE_LOLBIN_RUN_COMMAND
    Document contains instructions or visible command text involving Windows script/execution tools such as PowerShell, mshta, cmd, rundll32, or regsvr32
  • External relationship medium OOXML_EXTERNAL_REL
    External target in word/_rels/settings.xml.rels: https://www.mail-sender.online/it-it?t=eyJhbGciOiJIUzI1NiJ9.eyJ0cmFja2luZ190b2tlbiI6IjhkZjI3NmYwLWU5NzQtNDM1OC1hNzMzLTcx
  • 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.
