MITRE ATT&CK
T1204 Malicious Link T1566.001 Phishing: Spearphishing Attachment

The sample uses remote template injection and external relationships to point to a malicious document hosted at http://23.95.52.140/dhl/file2/receipt_download.doc. This indicates a likely phishing attempt, impersonating a DHL receipt to trick the user into downloading a secondary payload. The ClamAV detection as Doc.Downloader.Loda-7570590-0 further supports its role as a downloader.

Heuristics 4

  • ClamAV: Doc.Downloader.Loda-7570590-0 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Doc.Downloader.Loda-7570590-0
  • Remote template injection high OOXML_REMOTE_TEMPLATE
    Document references a remote template URL (http://23.95.52.140/dhl/file2/receipt_download.doc) — 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 high OOXML_EXTERNAL_REL
    External target in word/_rels/settings.xml.rels: http://23.95.52.140/dhl/file2/receipt_download.doc
  • 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.
