OpenSSL Heartbeat (Heartbleed) Vulnerability (CVE-2014-0160) and its High-Level Mechanics

There was a devastating security flaw in the OpenSSL implementation of the SSL / TLS protocol (CVE-2014-0160).

The vulnerability occurs in what is known as the heartbeat extension to this protocol, and it specifically impacts version 1.0.1 and beta versions of 1.0.2 of OpenSSL. Even though OpenSSL is just one implementation of the SSL / TLS protocol, it is the most widely deployed implementation.

In this SOC Talk, Elastica’s CTO Dr. Zulfikar Ramzan walks through the mechanics of the Heartbeat (Heartbleed) flaw (at a high level), how an attacker can exploit it, and its underlying ramifications.

It is important to stress that the flaw is not inherent to the SSL / TLS protocol itself, but rather to the specific OpenSSL implementation.

Valentine’s Day Visualized

Valentine’s Day is on the calendar, which means romantic obligations and heightened expectations are in the air. So in the name of love — or lust, like, or whatever is enough for you — we decided to explore the truth behind all those symbols, from red roses and candy hearts, to romantic home-cooked or fancy prix-fixe dinners.

How we did it? We surveyed ourselves. That is, every number you see in the Valentine’s day charts is made up. For once, our purpose was not to visualize and inform, but rather to make you smile. Happy Valentine’s Day!
