Cyberkrig mot Irans kärnkraftverk!

Iran bekräftar nu att kärnkraftverket i Bushehr har drabbats av superviruset Stuxnet.
– Ett elektroniskt krig mot Iran har inletts, säger en regeringstalesman.
Aftonbladet rapporterade i går om det mystiska datorviruset Stuxnet, som tycks vara en cyberattack riktad mot Irans kärnkraftverk.

Unlike most viruses, the worm targets systems that are traditionally not connected to the internet for security reasons.

Instead it infects Windows machines via USB keys - commonly used to move files around - infected with malware.

Once it has infected a machine on a firm's internal network, it seeks out a specific configuration of industrial control software made by Siemens.

Once hijacked, the code can reprogram so-called PLC (programmable logic control) software to give attached industrial machinery new instructions.

"[PLCs] turn on and off motors, monitor temperature, turn on coolers if a gauge goes over a certain temperature," said Mr O'Murchu.

"Those have never been attacked before that we have seen."

If it does not find the specific configuration, the virus remains relatively benign.
