WATCH: The Heartbleed Bug Explained Perfectly in This Succinct Video

Heartbleed, the bug that’s taken the internet by storm and forced the Canada Revenue Agency to halt online tax filing, is well-explained in a video made by Zulfikar Ramzan, MIT Ph.D. and CTO of cloud security firm Elastica.

The video is great because it doesn’t shy away from technical jargon but remains accessible to the layman, and at under 10 minutes, it’s neither too short nor too long to get the job done properly.
