Lately, we have seen some really bad vulnerabilities in regards to SSL (Heartbleed) and Bash (later dubbed “Shellshock”), along with some slightly “lighter” linux/open source ones.

In September of this year, Google first discovered a fallback attack for SSL v3.0, and they wrote published a paper on it:
Today, it was officially confirmed that SSL version 3.0 is no longer secure, and thus, it is no longer recommended in client software (ex: web browsers, mail clients, etc…) or server software (ex: apache, postfix, etc…).
This was dubbed the “POODLE” vulnerability, and given CVE-2014-3566

A “POODLE attack” can be used against any website or browser that still supports SSLv3.
Browsers and websites need to turn off SSLv3 as soon as possible in order to avoid compromising sensitive/private information. Even though a really small percent of servers/browsers are vulnerable (mozilla estimates 0.3% of the internet), that is quite large in the total number of users.

How can I check if my browser is Vulnerable?
The guys at dshield setup this nice browser check: For checking your browser, use:
