This domain is deliberately trying to look like Apple's OCSP (Online Certificate Status Protocol) server, but it's actually a subdomain of tushuokeji.net, hosted in China on a broadcasting network. Legitimate Apple services don't use third-party domains like this, and the lack of any SSL certificate means any connection would be unencrypted. The domain has no history in the Wayback Machine, no contact information, and its ownership is hidden from WHOIS. For a site that pretends to be part of Apple's security infrastructure, these are all warning signs of a phishing or man-in-the-middle setup. If you see this domain anywhere, do not interact with it. It's not a real Apple service and offers no trust signals whatsoever.
