MITRE ATT&CK
T1204.002 Malicious File

The file exhibits critical heuristic firings for remote template injection and external relationship, indicating a malicious document. The ClamAV detection explicitly names the 'Gamaredon' family. The embedded URL is likely used to fetch and execute a secondary payload, a common tactic for this malware family. No scripts were extracted, but the heuristics strongly suggest a downloader functionality.

Heuristics 4

  • ClamAV: Doc.Downloader.Gamaredon-9966166-1 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Doc.Downloader.Gamaredon-9966166-1
  • Remote template injection high OOXML_REMOTE_TEMPLATE
    Document references a remote template URL (https://wellmaintainedthingswithgreatgfeaturestogivenbestpeoplesaroundtheworldforbestfeeiv.dOTX=@link.emcdn.ru/QiRe6L) — 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://wellmaintainedthingswithgreatgfeaturestogivenbestpeoplesaroundtheworldforbestfeeiv.dOTX=@link.emcdn.ru/QiRe6L
  • 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.
