A new programming flaw known as “Bash Bug” is reported to give a serious threat to the IT world effecting millions of computers and other devices such as home internet routers and even the systems that are used to run factory floors and power plants.
The Bash Bug also known as “Shellshock”, affects a system software called Bash, which is found on a variety of 
Unix-based systems, potentially allows hackers to take control of a victim’s computer and run almost any operation, from opening, altering and deleting files to shutting down networks and launching attacks on websites.
Bash is found on Unix-based devices that are running the Linux and Mac OS X operating systems. Devices that use Unix in some form include many servers, routers, Android phones, Mac computers, medical devices and even the computers that create bitcoins. Systems running power plants and municipal water systems could also be affected by the bug, though security experts already recommend that these systems remain disconnected from the internet to avoid opening them to such risks.
Bash is a command shell which “tells the computer to do of what you want do”. Thus, the bug in Bash allows the hackers to take control over a victim’s device.
Thus, Bash is believed to be worse than “Heartbleed, which expose passwords and other sensitive data to hackers”.
As we wait for the development of a fix to this bug, it will be always helpful to run up-to-date security software on your devices.
