Virus Attacks a European Utility

A European utility reported that a virus attacked their Distribution SCADA system and this resulted in partial unavailability of the system functions. The utility reported they lost complete view of numerous distribution substations (for 3 days) by the operators in the control center. (#2)

It took approximately 40 person-weeks (over a 4 calendar-week period) to correct the problem. Since there was no electric power lost there was no requirement for the utility to report the incident. (#2)
