MITRE ATT&CK
T1204.002 Malicious File

The file exhibits characteristics of a malicious document downloader. The presence of 'OOXML_REMOTE_TEMPLATE' and 'OOXML_EXTERNAL_REL' heuristics, along with the unknown reputation URL 'https://url.pm/VrpAB', strongly suggests an attempt to load external resources. ClamAV detection as 'Doc.Downloader.Redline-9972754-0' further supports this, indicating the file is designed to download and execute a secondary payload. No scripts were extracted, limiting the analysis of the specific execution mechanism.

Heuristics 4

  • ClamAV: Doc.Downloader.Redline-9972754-0 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Doc.Downloader.Redline-9972754-0
  • Remote template injection high OOXML_REMOTE_TEMPLATE
    Document references a remote template URL (https://url.pm/VrpAB) — 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/webSettings.xml.rels: https://url.pm/VrpAB
  • 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.
