Are you ShellShocked?
A Security Advisory Note issued on 26.09.14 highlighted a potential threat to certain types of systems called ‘BASH’ or ‘ShellShock’. This is a newly discovered software bug that affects equipment built using the Linux platform and could allow hackers to control a user’s computer and devices attached to it.
Bash (Bourne Again Shell) is a piece of software in many Unix-based operating systems, including Linux. It’s a type of program that lets users command their computers. Shellshock is a hole in Bash that, when carefully accessed, lets an outsider’s code be processed and executed on a user’s computer.
Some of the equipment used in security systems may use Linux and therefore may be vulnerable to the BASH / ShellShock bug. The consequences of this can be very serious.
What do I need to do?
Contact your security systems installer. They should be able to advise what equipment is affected and what is being done about it.
