article imageShellshock bug attacks begin

By Tim Sandle     Sep 28, 2014 in Technology
Computer watchers have spotted several attacks on websites and servers using the serious Shellshock bug. This has resulted in several thousand infected servers being used to bombard web firms with data.
While the attacks have just started, millions of servers use software remaining vulnerable to the bug. As Digital Journal reported yesterday, Shellshock is the latest computer bug of concern. The virus potentially lets attackers run commands on that system. Systems at risk are those that run Linux as well as Apple Macs. Shellshock infects computer code called Bash, which is an acronym for “Bourne-again shell,” a Unix shell, developed for the GNU Project as a free piece of software.
According to the BBC, the number of attacks and compromises is set to grow following the code used to exploit the bug being widely shared according the hacker community.
Discussing the implications of the bug, security researcher Kasper Lindegaard from Secunia, is quoted by The Register as saying: "Bash enables hackers to execute commands to take over your servers and systems."
To add to this, Jaime Blasco writing on Alien Vault, said: "The vulnerability is critical since it can be exposed on web servers that use mod_cgi or code that calls the bash shell. Other systems that are probably affected are network services and daemons that use shell scripts with environmental variables."
The threat is so serious that several governments, including the U.S., have issued major alerts.
