MITRE ATT&CK
T1204.002 Malicious File: User Execution

The OOXML document contains heuristics indicating remote template injection and an external relationship, both pointing to the URL https://kryx.ru/Sdk1EB?&processing=subdued. This suggests the document is designed to fetch and execute a secondary payload from this external source. An embedded OLE object was also detected, which could contain further malicious content or exploit code.

Heuristics 4

  • Remote template injection high OOXML_REMOTE_TEMPLATE
    Document references a remote template URL (https://kryx.ru/Sdk1EB?&processing=subdued) — 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://kryx.ru/Sdk1EB?&processing=subdued
  • Embedded OLE object medium OOXML_OLE_OBJECT
    Document contains an embedded OLE object
  • 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.
