If you're wondering whether strm-m9-158.strm.yandex.net is a scam or safe to use, the short answer is that it's a legitimate subdomain belonging to Yandex, a major Russian internet company. This isn't a shady unknown entity trying to hide its identity. The domain resolves quickly, has a clean history on blacklists, and uses modern encryption.
However, there are a couple of technical red flags that keep it from being fully trusted. The server still accepts older, insecure versions of TLS, and the SSL certificate will expire in about 20 days. It also lacks some common security headers that would help protect against certain web attacks. For a streaming or content delivery server, these aren't dealbreakers, but they suggest the system isn't being maintained with the highest security standards.
If you're asking "is strm-m9-158.strm.yandex.net fake?" - no, it's real and part of a well-known network. But treat it as a backend server, not a consumer website. There's no public contact info or legal pages because there's no need for them here. If you're connecting to it through a Yandex service, you're safe. If you stumbled across it on its own, there's nothing to buy or sign up for - it's just infrastructure.
