MITRE ATT&CK
T1566.001 Spearphishing Attachment

The document contains external hyperlinks and a remote image beacon, suggesting it is designed to fetch content from external sources. The 'SE_PASSWORD_ARCHIVE_LURE' heuristic indicates the document instructs the user to open a password-protected archive, a common tactic to evade security scanning. The presence of external relationships and hyperlinks points towards a delivery mechanism for a secondary payload, likely malicious. No scripts were extracted from this sample.

Heuristics 5

  • Password-protected archive handoff high SE_PASSWORD_ARCHIVE_LURE
    Document gives password instructions for an archive or attachment — often used to keep payloads encrypted until after gateway scanning
  • Remote image (web beacon / tracking pixel) medium OOXML_IMAGE_BEACON
    Document references an external image URL — loads automatically on open, revealing IP address and timestamp to the server (used for phishing tracking and NTLM hash theft on corporate networks)
  • External relationship medium OOXML_EXTERNAL_REL
    External target in word/_rels/footer13.xml.rels: https://web.sunvn.net/facon_defense_ukrainienne_ru_2022.dotm
  • External hyperlinks (51) low OOXML_EXTERNAL_HYPERLINKS
    Document contains 51 external hyperlinks — clickable URLs are stored as external relationships. First target: http://nv.ua/opinion/melnyk/vozmozhen-li-v-ukraine-perehod-na-kontraktnuju-armiju-62503.html
  • 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.
