secure-app-kaiyun[.]com

secure-app-kaiyun.com is an active credential phishing site observed since its registration on May 19, 2026. The page title returned by the server – “开云体育入口页 - 热门赛事资讯与直播导航 - 即时更新” – indicates an attempt to masquerade as a sports portal, likely targeting users of the Kaiyun Sports service. The site responds with HTTP 200, confirming that the front‑end is reachable.

The domain resolves to the IPv4 address 177.210.187.75, which geolocates to Hong Kong. It is hosted behind the nameservers a12.share-dns.com and b12.share-dns.net, both of which are commonly associated with shared DNS services. The TLS certificate is issued by TrustAsia Technologies, Inc. under the LiteSSL RSA CA 2025 hierarchy, providing a valid HTTPS endpoint but offering no indication of legitimate ownership. Registration was performed through Gname.com Pte. Ltd., a registrar known for rapid bulk registrations.

Reputation data shows the domain is listed on three public blocklists and has been flagged by two of ninety‑five VirusTotal scanners, reflecting limited but concrete detection. Gridinsoft assigns a trust score of 0 out of 100, effectively classifying the site as fully untrusted. The URL has been added to block lists maintained by PhishDestroy, MetaMask, and SEAL, and appears in a single AlienVault OTX pulse, reinforcing the consensus that it is used for credential harvesting.

Defenders should immediately block network resolution of secure-app-kaiyun.com and its associated IP address at perimeter firewalls and DNS filtering layers. Continuous monitoring of outbound traffic for authentication attempts to the domain is advised, as the site may be employed to capture user credentials. Given the active SSL certificate, TLS inspection may be required to uncover any hidden data exfiltration. Incident response teams should also correlate any recent login failures or unusual account activity with this domain to identify potentially compromised accounts.
