TLS: encrypted traffic can still reach a scam website
Transport security protects a connection; it does not validate the business at the other end.
Research articles and reference entries are published in English. Navigation is available in seven languages.
What the connection protects
TLS provides cryptographic protection for communication between endpoints. In ordinary HTTPS browsing, certificate validation helps the browser authenticate the hostname it requested. Encryption and integrity protection limit interception and alteration in transit.
The important word is requested. A deceptive domain can operate its own valid HTTPS service. Securely delivering a fraudulent page does not make its contents honest, its owner trustworthy or its requested wallet action appropriate.
Separate the checks
Inspect the destination name, the page's claim and the requested action separately. If a supposed account notice sends you to an unfamiliar domain, a valid certificate does not resolve the mismatch. If the browser reports a certificate failure, do not treat clicking through it as routine troubleshooting for a financial session.
A research report should distinguish an expired certificate, an impersonating domain and malicious page content. They involve different evidence and different remedies. Reissuing a certificate would not fix a deceptive signing request. See domain resolution and the boundary between a page and a signature.
