MITRE ATT&CK

T1204.002 Malicious File

The sample exhibits characteristics of a malicious OOXML document, specifically triggering heuristics for remote template injection and external relationships pointing to the URL 'https://provit.uk/Ib9yLe?&shoelace=strong&skyscraper=discreet&roll=thoughtful&mimosa=wacky&vulture'. Additionally, an embedded OLE object was detected, which likely serves as the mechanism to execute the payload from the remote template. The combination of these findings strongly suggests an attempt to download and run a secondary malicious file.

Heuristics 5

Remote template injection high OOXML_REMOTE_TEMPLATE

Document references a remote template URL (https://provit.uk/Ib9yLe?&shoelace=strong&skyscraper=discreet&roll=thoughtful&mimosa=wacky&vulture) — 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/Ib9yLe?&shoelace=strong&skyscraper=discreet&roll=thoughtful&mimosa=wacky&vulture
Embedded OLE object medium OOXML_OLE_OBJECT

Document contains an embedded OLE object
Suspicious extracted artifact info EXTRACTED_FILE_STATIC_TRIAGE

One or more files extracted from inside this sample matched static suspicious-content checks such as script obfuscation, encoded payload blobs, packed data, or execution/download terms.
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.
