Homeland Security issues warning of elevated security risk from an online worm “bash bug”. If you own a mac computer, you are waking up to the potential of massive damage from one your first worries that historically affect windows computers. This time the opposite holds true. Nearly every major system from Apple Mac OS, Android, Linux and Unix servers and major web servers like Apache are threatened – not windows-based computers. Apple has stated that a vast majority of Mac computer are not affected and it is limited to systems which have been altered for server and other outside access but is working on a patch.
What is the “bash bug” aka “shellshock”?
- attackers can potentially take over the device’s operating system, access confidential information and use it as if it were their own.
- the worse case scenarios show potential vulnerability in systems that run power plants, medical devices, municipal water systems. On the annoying end, mac computers and android devices could be taken over through public wifi such as those found at coffee shops and airports.
- serious enough that homeland security has issued venerability warning
What we know about “shellshock / bash bug:
- let’s attackers take over the devices operating system, access confidential information and use it as if it were their own.
- apple mac computers, android devices and big computer systems using unix, linux, apache
- most serious worse case risks to in systems that run power plants, medical devices, municipal water systems.
- you can be affected directly on mac computer attached to a public wifi hotspot such as a coffee shop or airport
- discovered by a stephane chazelas of alkamai technologies
- does not affect windows computers.
What you need to do right now:
