Update: 04/10/2014 – The list below are the websites that were vulnerable as of April 8, 2014 at 16:00 UTC. However, OpenSSL (1.0.1 to 1.0.1f) that uses the TLS heartbeat extension is used by almost every major website including Google, Twitter, Amazon, Yahoo, Microsoft as well as the major Web Hosting Providers. In the last 24-48 hours, the companies are now acknowledging they have implemented the fixes (upgraded to OpenSSL 1.0.1g or recompliled with the -DOPENSSL_NO_HEARTBEATS flag). So I would imagine that most IT Security Professionals will be recommending that all passwords be changed several times in the upcoming weeks and never reusing an old password.
Here’s the list of servers that were vulnerable to the Heartbleed Bug as of April 8, 2014 16:00 UTC as reported on a Heartbleed-Masstest.
