Lion.secure.dyn.riotcdn.net is a subdomain of riotcdn.net, a domain associated with Riot Games (the company behind League of Legends). This type of hostname is typically used for delivering dynamic game content, not for a standalone website. The 404 error you're seeing means the specific path you requested doesn't exist — not that the whole domain is fake. There's no web archive history for this subdomain, which is normal for a backend endpoint that changes often. The site has a valid SSL certificate and sits on Cloudflare's network, both marks of legitimate infrastructure. So is lion.secure.dyn.riotcdn.net a scam? No evidence points that way. It's just a technical service that isn't meant to be browsed by people. If you were expecting a real website here, you may have the wrong URL. Otherwise, there's nothing to worry about.
Yes — lion.secure.dyn.riotcdn.net looks mostly safe
In plain English
This is a subdomain likely used for content delivery, but it's currently returning a 404 error. That doesn't mean it's a scam — it just means the page you're trying to reach doesn't exist. There's no information about who runs it, which is normal for a technical subdomain, but you won't find contact details or a business profile here.
Where the score comes from
Solid encryption with a valid certificate and modern TLS, no malware flags, but the site doesn't set common browser protections — that's more of a concern for interactive sites, less so for a CDN endpoint.
No WHOIS data for this subdomain, which is normal for a technical subdomain, but the parent domain (riotcdn.net) likely belongs to Riot Games. Without confirmation, the ownership remains a bit unclear.
Clean record on blacklists and Google Web Risk. No history in the Wayback Machine, but that's expected for a dynamic CDN subdomain — not a red flag.
No contact info, about page, or social links, but that's totally normal for a backend CDN hostname. This isn't a consumer-facing business, so transparency expectations don't apply.
No privacy policy or terms of service, which would be a problem for a commercial site, but for a technical subdomain that just serves content, legal pages are irrelevant.
Hosted on Cloudflare with fast load times and multiple IPs. Missing DNSSEC and a few security headers, but for a CDN subdomain those are often handled at the origin — nothing alarming.
