October Patch Tuesday Addresses Stuxnet Vulnerability

Although there was uncertainly, Microsoft's October Patch Tuesday did in fact address a vulnerability that Stuxnet "currently leverages," reports AFP.

Microsoft has already patched two of the four holes used by Stuxnet. This patch closes a third door to the malicious software.

The worm is designed to attack Siemens industrial control systems. The largest number of attacks has occurred in Iran, and is believed to have been built to specifically target Iran's Bushehr nuclear reactor. Iran admits that Stuxnet has infected at least 30,000 Windows PCs in the country, and blames Western countries for creating it.
