 Heartbleed bug

Heartbleed was the popular word of the internet last week, and it still is. What exactly is heartbleed though?

Heartbleed is a major bug within the authentication system for website which use OpenSSL to authenticate website logins. The problem is, a great majority of the internet uses OpenSSL as their authentication system.

The fix against this bug is to update the OpenSSL software on webservers. Major websites like Yahoo, Facebook, Google and plenty of others were affected, however they quickly patched the bug. After the fix is applied, users should change their passwords and make it complex.

Upon the discovery of this bug, the Canada Revenue Agency (CRA) temporarily suspended their online portion of the website. However, today it is reported that on average 900 Canadian social insurance numbers were stolen using the heartbleed bug.
