Symantec has issued a dossier on Stuxnet depicting ins-outs of the malware, who were the targets & what was the objective.

The malware intercepts commands sent to the drives from the Siemens SCADA software, and replaces them with malicious commands to control the speed of a device, varying it wildly, but intermittently.
