Experts: Israel’s Cyber-Defense Can Stop Stuxnet Worm

There are tens of thousands of attempted virus attacks on Israeli systems each week – but Israel is “well-equipped” to fend off an onslaught of computer viruses, such as the one that has plagued Iran in recent months, experts say.
Iran has been struggling to control a virulently destructive, surprisingly agile computer virus known as Stuxnet, which has invaded – and hijacked – over 30,000 computers in Iran. Unlike standard viruses, Stuxnet is especially destructive, as it attempts to take control of a computer’s programmable logic controller (PLC), which runs supervisory control and data acquisition software (SCADA) of machinery and industrial systems, like the ones that control manufacturing, energy production, and other critical infrastructure.
Stuxnet is seen as especially sophisticated, as well, because the PLCs it attacks – it seems to favor systems made by Germany’s Siemens, which, by coincidence, are heavily used in Iran – are based on obtuse programming language, not on Windows or Linux, like most viruses. And, according to security experts, Stuxnet has the ability to hide its tracks – erasing traces of its activity recorded in computer logging systems – making detection all the more difficult.
