Computer security researchers are warning that a new version of the sophisticated cyberweapon that sabotaged Iran’s nuclear program could be the precursor to a new wave of cyberattacks.

A computer virus has infected the cockpits of America’s Predator and Reaper drones, logging pilots’ every keystroke as they remotely fly missions over Afghanistan and other warzones.

A recent cyber attack on Iran's nuclear program could have triggered a disaster comparable to the one in Chernobyl 25 years ago, Russia's envoy to NATO said.

Sanctions and possible sabotage may be slowing Iran's nuclear drive, reducing the risk that Israel might resort to military strikes against the Islamic Republic's atomic sites any time soon. Technical glitches and other hurdles for Iran's uranium enrichment programme could also provide more time for diplomatic efforts by major powers to persuade it to curb work the West fears is aimed at making bombs, a charge Tehran denies.

Experts dissecting the computer worm suspected of being aimed at Iran’s nuclear program have determined that it was precisely calibrated in a way that could send nuclear centrifuges wildly out of control, lending credence to the theory that the worm was designed as an offensive counter-proliferation effort.

Stuxnet is the first worm of its type capable of attacking critical infrastructure like power stations and electricity grids: those in the know have been expecting it for years.

The Stuxnet worm is mutating and wreaking further havoc on computerised industrial equipment in Iran where about 30,000 IP addresses have already been infected.

A virus designed to swipe passwords from online gamers has inexplicably popped up in some laptop computers aboard the International Space Station.

Botnets are secretly installing themselves on thousands or even millions of personal computers, banding these computers together into an unwitting army of zombies, and using the collective power of the dragooned network for spam and committing Internet crimes.

A computer worm that spreads via AOL instant messaging is being used to build an extensive "botnet" of remote-controlled PCs. The goal appears to be to create a huge network of remote-controlled machines, known as a "botnet." Botnets may be used to send out huge quantities of junk e-mail or attack business websites, or create click fraud on Internet ads.
