By now, we all know what a huge deal Heartbleed is. The massive vulnerability in OpenSSL protocol impacted 66% of all sites on the Internet at the time of its discovery, and now companies are scrambling to fix the issue. Most big companies seem to have done a pretty good job of acting quickly, but this bug is several years old so users have been at risk for quite some time regardless of how quickly a site might have patched the flaw. As such, the cybersecurity experts at LWG Consulting have compiled a great list of all the huge sites that were impacted by Heartbleed.
