Symantec Continues to Undercover the Secrets of Stuxnet

Symantec has released version 1.3 of their document entitled "W32.Stuxnet Dossier" available by clicking here, which provides additional details on how it not only targets specific controllers within the Siemens PCS7 control system (S7-315 or S7-417 CPUs with CP-342 Profibus modules), but also two specific variable frequency drives manufactured by Fararo Paya (Tehran, Iran) and Vacon (Finland).  The more that is discovered about Stuxnet, the more it demonstrates the sophistication of its developers and the targeted nature of the attack.
