Malware Threatens Manufacturing Software Systems Worldwide.
Managing Automation (7/19, Chiappinelli) reported, "Manufacturers worldwide have been put on notice that an insidious virus targeting supervisory control and data acquisition (SCADA) systems is on the loose." The targets of the virus "are Siemens' SIMATIC WinCC and PCS7 software, integral components of the distributed control and SCADA systems that facilitate production operations in many process manufacturing companies."
The Wired (7/19, Zetter) "Threat Level" blog described the virus as "a sophisticated new piece of malware that targets command-and-control software installed in critical infrastructures" that "uses a known default password that the software maker hard-coded into its system. The password has been available online since at least 2008, when it was posted to product forums in Germany and Russia. The password protects the database used in Siemens' Simatic WinCC SCADA system, which runs on Windows operating systems."
