Worm Alert

The bad guys are not just interested in playing with Mom's desktop.

Computer hackers have begun targeting power plants and other critical operations around the world in bold new efforts to seize control of them

These worms are attacking SCADA software, which controls oil/gas transmission pipelines and some other utility operations.

AND they are using company networks to migrate from Windows-based systems into manufacturing-control systems such as those made by Siemens, a competitor to Rockwell/Allen-Bradley. You can safely bet that AB control systems are on the target list, as well.
