Infrastructure published by Volexity for UTA0560, one of the Chinese threat actors that chained Google Chrome (CVE-2026-85046, CVE-2026-87491) and Windows (CVE-2026-85880) zero-days in early September 2026. shinewrist[.]net and cloud.shinewrist[.]net hosted the exploit chain; opusaccel[.]top and its subdomains (ocr., www.) served as command-and-control for the GRIMWEDGE backdoor.
