Siemens Statement on Malware Attack

I have received this statement from Siemens regarding the situation:

"Siemens was notified about the virus that is affecting its Simatic WinCC SCADA (Supervisory Control and Data Acquisition) systems on July 14.  The company immediately assembled a team of experts to evaluate the situation.  Siemens is taking all precautions to alert its customers to the potential risks of this virus.

"Siemens is reaching out to its sales team and will also speak directly to its customers to explain the circumstances. We are urging customers to carry out an active check of their computer systems with WinCC installations and use updated versions of antivirus software in addition to remaining vigilant about IT security in their production environments."
