MITRE ATT&CK
T1566.001 Spearphishing Attachment

The file is identified as malicious by ClamAV with a specific detection name associated with the Gamaredon group. Heuristics indicate remote template injection and external relationship, pointing to the URL http://semara.ru/ADMIN/necessarily/false/false.dot as a source for malicious content. The document body appears to be a lure, possibly related to vaccination certificates, to trick users into interacting with the malicious template.

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 (http://semara.ru/ADMIN/necessarily/false/false.dot) — 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: http://semara.ru/ADMIN/necessarily/false/false.dot
  • 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.
