MITRE ATT&CK
T1204.002 Malicious File

The OOXML document contains heuristics indicating remote template injection and external relationship manipulation, pointing to a malicious intent. The embedded URL 'https://kryx.ru/8IJcFB?&bangladesh=abstracted&change' is likely used to download and execute a secondary payload. No VBA scripts were extracted, but the document structure itself suggests a delivery mechanism for malware.

Heuristics 3

  • Remote template injection high OOXML_REMOTE_TEMPLATE
    Document references a remote template URL (https://kryx.ru/8IJcFB?&bangladesh=abstracted&change) — 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/8IJcFB?&bangladesh=abstracted&change
  • 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.
