MITRE ATT&CK
T1204.002 Malicious File T1566.001 Spearphishing Attachment

The file is identified as malicious by ClamAV with a detection name suggesting it's a downloader. Heuristics indicate remote template injection and external relationships, pointing to the use of a malicious URL. The primary IOC is the suspicious shortened URL found in the heuristics, which likely leads to the download of a secondary payload.

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://cutt.ly/KneKr2m) — 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.
    URL https://cutt.ly/KneKr2m
  • External relationship medium OOXML_EXTERNAL_REL
    External target in word/_rels/webSettings.xml.rels: https://cutt.ly/KneKr2m
    URL https://cutt.ly/KneKr2m
  • 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.
