High confidence phishing identified. The domain polar.sh hosts a SPA that mirrors polar branding and uses numerous external JavaScript bundles, plus an iframe, which strongly indicates an impersonation site designed to collect credentials or other sensitive data under the Polar brand. The static HTML contains 0 forms, yet dynamic scripts render input fields, a common tactic for credential phishing. The SSL certificate is valid, issued by Let's Encrypt, and the domain appears freshly provisioned with a Jan 27 2026 issuance date, suggesting rapid deployment for abuse. The combination of brand impersonation, SPA-based credential capture, and suspicious monitoring POSTs warrants urgent takedown action.
