MITRE ATT&CK
T1204 Malicious Link T1204.002 Malicious Link: Malicious File T1059 Command and Scripting Interpreter T1059.001 Command and Scripting Interpreter: PowerShell T1059.003 Command and Scripting Interpreter: Windows Command Shell

The file exhibits critical heuristic firings for CVE-2017-0199 and CVE-2022-30190, indicating it's designed to exploit these vulnerabilities. It embeds an OLE object that references the URL http://47.112.178.28:39119/index.html, which is likely used to download and execute a malicious payload. The ClamAV detection further confirms its malicious nature.

Heuristics 6

  • CVE-2022-30190 — Follina stage-1 external HTML oleObject critical CVE likely CVE_2022_30190
    External OLEObject relationship targets a remote .html with the Follina delivery shape (oleObject -> HTTP(S) HTML with trailing Moniker '!'). In live Follina samples the ms-msdt: trigger is served by the remote HTML, not the document itself.
  • OOXML OLE2Link remote loader — CVE-2017-0199 related high CVE related CVE_2017_0199_RELATED
    Document contains an o:OLEObject Type=Link whose external oleObject relationship points to a remote URL. This is the OOXML OLE2Link activation shape associated with CVE-2017-0199 delivery, but the local file does not expose URL Moniker bytes or a weaponized extension/content type, so the exact CVE cannot be proven statically.
  • ClamAV: Win.Exploit.CVE_2022_30190-9951234-1 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Win.Exploit.CVE_2022_30190-9951234-1
  • External relationship high OOXML_EXTERNAL_REL
    External target in word/_rels/settings.xml.rels: file:///C:\Users\oksec\Desktop\更新包\web仿真蜜罐_20210326_v1.4\反制文件\Normal.dot
  • External OLE object relationship high OOXML_EXTERNAL_OLE_OBJECT
    Document contains an oleObject relationship whose target is an external HTTP(S) URL. Office resolves this through OLE/object update paths rather than as a normal user-clicked hyperlink.
  • 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.
