MITRE ATT&CK
T1566.001 Spearphishing Attachment T1203 Exploitation for Client Execution

The sample exhibits high-confidence indicators of remote template injection and the presence of an embedded OLE object. These techniques are commonly used to download and execute secondary payloads. The embedded URL, https://provit.uk/RV9M6k?&cellar=barbarous&prize=garrulous&spotlight=lethal&brother=festive&shoe-horn=weak&pocket, is highly suspicious and likely serves as the source for this payload. The overall confidence is high due to the combination of these indicators.

Heuristics 4

  • Remote template injection high OOXML_REMOTE_TEMPLATE
    Document references a remote template URL (https://provit.uk/RV9M6k?&cellar=barbarous&prize=garrulous&spotlight=lethal&brother=festive&shoe-horn=weak&pocket) — 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://provit.uk/RV9M6k?&cellar=barbarous&prize=garrulous&spotlight=lethal&brother=festive&shoe-horn=weak&pocket
  • 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.
