Modern servers prefer ECDHE for forward secrecy, but many still accept RSA key exchange when an attacker manipulates the handshake. These domains are downgrade-attackable: a MITM forces RSA, harvested traffic from that session is decryptable with one stolen cert key. This finding is independent of quantum risk — it's a present-day exposure too.
