Kuna Systems Corporation presents itself as a login portal for the Kuna app, but the signals around this site raise serious concerns. A legitimate SaaS platform that handles user accounts typically has clear ownership records, a visible company behind it, and published legal policies. Server.kunasystems.com has none of those.
The domain registration is completely hidden, with no match in the public WHOIS database. The site has no contact information, no about page, and no social media presence. For a business asking for your sign-in credentials, that level of opacity is unusual and worrying. The copyright in the footer dates to 2014-2015, yet the domain has no history in the Wayback Machine, which is contradictory for a service supposedly operating that long.
If you are considering signing in here, think about what a real SaaS login looks like: you know the company name, they have a support email or phone number, and their legal policies are easy to find. This site has none of those basics. Until those gaps are addressed, treating server.kunasystems.com as unsafe is the only reasonable call.
