The sample leverages the CVE-2022-30190 (Follina) vulnerability, indicated by multiple critical heuristic firings. This exploit is designed to download and execute a second-stage payload from the external URL https://www.sputnikradio.net/radio/news/1134.html. The document body, while truncated, discusses staff reductions due to geopolitical events and a pandemic, potentially serving as a lure to encourage opening the malicious document.

Heuristics 5

  • 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 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.
