PQC-Scanner

The PQC Network Scanner is a purpose‑built assessment tool designed to help organisations understand their cryptographic exposure as they transition toward a post‑quantum security posture. Unlike traditional TLS scanners that focus solely on certificate validity or classical cryptographic strengt...

CVE-2026-118778

The Forge (also known as node-forge ) JavaScript TLS implementation is vulnerable to a crash in versions prior to 1.4.1 . The flaw exists in the TLS client when using forge.tls.createConnection(), c.session.serverCertificate, and RSA key exchange . Specifically, the client checks the incorrect pr...

DHEater

DHEater DHEater is the proof-of-concept implementation of the DHEat attack CVE-2002-20001. It saturates a server's CPU by enforcing Diffie-Hellman ephemeral DHE or elliptic-curve Diffie-Hellman ephemeral ECDHE key exchange over both TLS and SSH. For further information about the attack visit the...

rustls: An unauthenticated ServerHello poisons the per-name key-exchange record, so later ClientHellos carry only a classical X25519 share

Summary The client records the server-selected key-exchange group per server name when it processes the ServerHello, before the server is authenticated. A network attacker can answer one connection attempt for a target name with a ServerHello that selects X25519 and close the connection. Later...
