This HeartBleed bug has been in OpenSSL for almost 2+ years (OpenSSL versions 1.0.1 through 1.0.1f) before its publicly announced discovery 3 days back …. The bug was discovered by Neel Mehta who is from the Google’s security team.

The Heartbleed bug, affects any website and service running specific versions of OpenSSL (1.0.1 through 1.0.1f). Many sites must be using older versions of OpenSSL that are not vulnerable and many have likely updated their OpenSSL to the latest fixed version.

However, there are many tools available online where you can check or test whether the website is vulnerable to this Bug or not.

Also, Cnet have compiled a list of the top 100 sites across the Web, and checked to see if the Heartbleed bug was patched on them, You can check out the list by visiting this URL:

What Should You Do?

If you own any website which is using OpenSSL , it is advised to update it to the latest fixed version and reissue your security certificates.

For an Average User, there is nothing much you can do about this. Try avoiding the vulnerable websites for few days until you receive any official notification or notice regarding the fix.

Yes, you can change your passwords too,. but it won’t help until the website has fixed the issue. So watch out for their blog, newsletters, facebook page  for the related news.
