Signals, not verdicts. A domain appears here because heuristics matched its name, its infrastructure or the page it served on its first day. Where a model has looked at it, that is shown as an opinion with a confidence, not as a finding. Nothing on this page says a site is malicious. Read the evidence and decide for yourself.

Model opinions

Second opinionsuspiciousconfidence 55%· claude-opus-5

Site is unreachable (Cloudflare 525, no origin content), so nothing on-page to judge; the 'itau' brand match is a substring artefact of '21bit-au', which reads far more like a geo-targeted ('-au') mirror domain for the 21Bit crypto casino — a shape often used for unlicensed-gambling access mirrors, but unproven without content.

First passlooks benignconfidence 95%· claude-haiku-4-5

The page is a standard Cloudflare SSL/TLS error (525) message displayed when a domain's origin server is misconfigured. This is a hosting-provider error placeholder, not an impersonation attempt. The domain name contains 'itau' (a Brazilian bank) and 'bit', but the error page itself makes no attempt to impersonate anyone—it is transparently showing a Cloudflare infrastructure error with standard remediation guidance.

A model looked at the screenshot and page text and wrote what it thought. It can be wrong, and it is not a finding.
