A Turkish grad student has devised a serious, real-world attack on Twitter that targeted a recently discovered vulnerability in the secure sockets layer protocol. The exploit by Anil Kurmus is significant because it successfully targeted the so-called SSL renegotiation bug to steal Twitter login credentials that passed through encrypted data streams. When the flaw surfaced last week, many research
Marsh Ray has published a new attack on the TLS renegotiation logic. The high level impact of the attack is that an attacker can arrange to inject traffic into a legitimate client-server exchange such that the TLS server will accept it as if it came from the client. This may allow the attacker to execute operations on the server using the client's credentials (e.g., order a pizza as the client). H

Intro If you know why you're here and what the "SSL Blacklist" extension does, you can install it from here, or from the pretty link in the right column. Otherwise, read on for a description and some tech details. Update 12/31/2008 SSL Blacklist now detects and warns about certificate chains that use the MD5 algorithm for RSA signatures. An attack has been demonstrated yesterday that highlights th
When your app lets the OS choose the TLS version: It automatically takes advantage of new TLS protocols added in the future. The OS blocks protocols that are discovered not to be secure (e.g. SSL3 and TLS 1.0). This article explains how to enable the strongest security available for the version of .NET Framework that your app targets and runs on. When an app explicitly sets a security protocol and
