By now many of you have become familiar with a new IT systems vulnerability nicknamed "Shellshock".

With the wave of systems breaches and vulnerability exploits making the headlines during the past 9 months, it is understandable that there is concern about what the Shellshock vulnerability might mean to your IT systems. We wanted to give you our update on this latest vulnerability and what we are seeing so far.

What is it?

Shellshock impacts a Linux-based program called Bash that is incorporated into many other technologies – from network routers to websites. That does not mean that all of them are vulnerable. Vulnerability depends on how the Bash code is accessed. In certain cases, the way the Bash code is accessed creates an opening for hackers to access your systems and steal information.

If you are looking for a good "Shellshock 101" primer, this article concisely explains the Shellshock vulnerability, why most end users are not impacted directly, and how to protect your systems.
