Triple Handshake TLS Attacks Target Resumption, Renegotiation

A team of researchers has published a paper that explains a number of attacks against websites and Web-based applications running TLS. The researchers’ techniques do not exploit implementation errors, the most common attack vector against encryption securing online communication, instead focus on...

Internet Bug Bounty: TLS Triple Handshake Attack

More details are at https://secure-resumption.com 2 Scenario ====== Consider a client C that normally authenticates to a server S using a client certificate. If C uses the same certificate to authenticate to a malicious server M, then we show that M can use C's certificate to authenticate its own...

OpenSSL SSL_OP_NETSCAPE_REUSE_CIPHER_CHANGE_BUG Session Resume Ciphersuite Downgrade Issue

The version of OpenSSL on the remote host has been shown to allow resuming session with a weaker cipher than was used when the session was initiated. This means that an attacker that sees i.e., by sniffing the start of an SSL connection can manipulate the OpenSSL session cache to cause subsequent...
