Since our post about the Bash Bug (aka Shellshock), new information has come to light. And while some software providers are yet to release statements or system patches, we now know more about how you can protect your devices from the serious security vulnerability.

What is the Bash bug?

Bash bug is the biggest IT system vulnerability in recent history and affects Bash, a Unix shell used by many different IT platforms.

Hackers are able to use the vulnerability to take control of devices – potentially hundreds of millions of computers globally.

Are my digital devices at risk?

There has been a lot of hype about the Bash bug. So at this stage, there’s no reason to panic. However, it’s important to know which systems are under threat – and how to safeguard your confidential business information.

Some Mac OS X systems are affected. Firewalls, routers, switches, WiFi, network attached storage, security systems, printers and phone systems are under threat. Basically, if a device uses Bash, it is probably affected. Both big and small brand TVs and entertainment equipment could also be in trouble.

Apple releases OS X bash update

On September 29, Apple released the OS X bash update for OS X Mavericks, to patch a vulnerability in the Unix shell.

If that sentence sounds like gobbledygook, you don’t need to worry. Your software provider will install patches as they come available. You only need to take urgent action if you use advanced Unix settings on a Mac device.

How can I safeguard my digital devices?

Like Apple, Fortinet – which we highly recommend – released an update within 24 hours of the Bash bug discovery.

Many other companies are still in PR mode, so the full extent is yet to be understood. The reason they haven’t released statements is to avoid exposing their customers until a working patch or fix is available.

In the meantime, there are some steps you can take:

1. Check with your firewall vendor. Some firewalls have already released intrusion prevention services to prevent the exploit entering your network or hosting.
2. Collate a list of all your devices that are connected to a network or the Internet.
3. Ask the vendor if you are affected. Check their blogs and social pages for updates.
