MITRE ATT&CK
T1566.001 Spearphishing Attachment

The file is identified as malicious by ClamAV, specifically as a Doc.Downloader.IcedID variant. Heuristics indicate the use of remote template injection and external relationships pointing to 'https://donattelli.com/test/ssi/content.dotm', suggesting an attempt to download and execute a secondary payload. This aligns with the typical behavior of IcedID, which often uses social engineering to trick users into enabling macros or downloading further stages.

Heuristics 4

  • ClamAV: Doc.Downloader.IcedID-8f0bf81ff0df2060-9955147-0 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Doc.Downloader.IcedID-8f0bf81ff0df2060-9955147-0
  • Remote template injection high OOXML_REMOTE_TEMPLATE
    Document references a remote template URL (https://donattelli.com/test/ssi/content.dotm) — 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://donattelli.com/test/ssi/content.dotm
  • 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.
