MITRE ATT&CK
T1204.002 Malicious File

The file is a malicious OOXML document that uses a remote template injection to download a payload from the URL http://0300.0003.0215.0244/ore/o.wbk. ClamAV identified this as Doc.Downloader.Redline-9972754-0, indicating a downloader functionality. No VBA scripts were explicitly extracted, but the heuristic firings strongly suggest macro-based execution leading to payload retrieval.

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 (http://0300.0003.0215.0244/ore/o.wbk) — 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.

  • Embedded URL info EMBEDDED_URL
    One or more URLs were extracted from the document. The URL itself is not a detection — context-specific rules above attribute URLs they actually evaluated; this rule lists URLs that were present in the bytes but were not otherwise tied to a specific finding.
