Rules of engagement between different countries should be established before a major Web-based attack takes place according to BT Group’s US chief security technology officer, Bruce Schneier.

What is Duqu?

The team behind Stuxnet, the complex malware used to attack Iran's nuclear program earlier this year, has produced another worm, dubbed "Duqu" by McAfee Labs.

Due to the complexity and sophistication of the code contained within the Stuxnet worm, the possibility of it being used to take control of a nuclear warhead is high, according to a security expert.

Security analysts have been predicting the emergence of mobile malware for many years. In 2011, the criminals have finally come through by attacking Google's popular Android OS. Meanwhile, the sophistication of Stuxnet — anasty piece of code that infected a nuclear power facility — has alarmed researchers who believegovernments are stockpiling tools for cyberwar. Looking ahead, it seems a cataclysmic Cloud failure is just around the corner.
